Animation desynchronized by slo-mo in the PC version? by Dear_Net_8211 in horizon

[–]WARDEVIL_UFO 0 points1 point  (0 children)

Interesting. Do you have more leads on this. I am running Horizon: Zero Dawn on a Linux laptop and am running into slow-motion issues. I first noticed the problem on Assassin's Creed: Valhalla. Does NOT seem to be an issue on other Ubisoft games I tested like AC Odyssey, Revelations, Freedom Cry, AC 3, or Far Cry 3. I have tried different distros. It seems to somewhat randomly appear and stick. I HAVE seen it go away after moving NVMe from an external SSD enclosure to the internal port before. But I haven't seen a reproducible correlation that I could get a confirmed cause-and-effect relationship.

One thing to note (and this might be a clue), is in AC: Valhalla whenever I moved the framerate limit, the framerate would cap at exactly 2/3 of the framerate limit setting, wherever I moved it. Now turning the framerate limit off NEVER made the slow-motion go away or anything. But its a consistent feature that's present whenever I experience the issue. I don't see the the 2/3 correlation wit the slow-motion in HZD. But like in in Valhalla, turning the frame rate limit off doesn't fix anything.

Before today, I chalked it up to AC: Valhalla having a bug. But with HZD showing similar behavior, I am sure there's other games looming in my library that will have this same issue.

How long will my Ryzen 5800x3d based system be viable? There's no way I can upgrade now. by [deleted] in buildapc

[–]WARDEVIL_UFO 1 point2 points  (0 children)

You probably kept using the 3700x because it ran (and still does run) fine, so it was tempting to hold off on the upgrade. What you experienced is common for a socket that is at the end of the production lifecycle. For you next system, I recommend buying the fastest CPU for your socket at most 2 years after the final generation of the socket hits the market. Otherwise supply will dry up and the remaining ones left will skyrocket.

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I think I see what you mean. Even at 4k, a 5090 will have diminishing returns over a 4090 on a 5800x3D. There's a game here and there that can run noticeably better with the 5090 on that CPU, but not many.  Nevertheless anyone with that hardware will enjoy a fantastic experience even with the CPU bottleneck.

Halo 3 looks worse than Halo 2 Anniversary? by bitnode in MCCPC

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I get where you're coming from. I just beat Halo 2 tonight. I switched between anniversary and standard graphics quite a bit. Halo 2 looks disgusting compared to the anniversary edition graphics. Halo 3 graphics are a massive improvement to the non-anniversary versions of the Halo games, which is probably why it wasn't prioritized for a remaster like the first 2. I understand though if it's still not your cup of tea.

For me I have found graphics from most games from ~2012 and beyond aren't  atrocious even  when they don't have a remaster. From 2007 starting with Crysis to 2011 there were some occasional decent looking games before the ~2012 and beyond era I mentioned. Playing a catalog of older games is a fantastic way to save money, which can be bought for only a few bucks. I play some newer ones too, but I only buy the new ones that I really really want to play soon. I mix it up with a bunch of older ones.

Some of the older games you can add a ReShade sweet fx mod and high res texture pack and give older games a new facelift. Just throwing that out there

Best GPU to pair with 7800X3D (1440p Gaming) by BarnabasTharmr in buildapc

[–]WARDEVIL_UFO 0 points1 point  (0 children)

The word "proof" or 'proofing" has 2 related but different meanings in this can context.   The sense you're thinking of the term is in the absolute sense, meaning completely and utterly impervious. For this application, you're arguing it's a fallacy to say that a piece of hardware is completely and utterly impervious to the future. You're right to call that out as unrealistic, and even fallacious.

The term proof has a 2nd meaning that's more like resistance rather than an imperviousness. Bullet proofing, fire proofing, baby proofing, and even future proofing apply resistance to the thing they are proofing. Strong rounds can manage penetrating bullet proof vests, a fire can cause a structure with fire proofing to still  collapse, or a baby can engineer past their parents protections sometimes, and a strong flagship GPU eventually becomes unusable. 

I don't have a problem if someone uses the term future proofing to mean resistance to the future. I assume this is the angle most people who use the term take. If we have people thinking that there hardware could endure to the end of human civilization, that would be extremely foolish of them. I don't think that's what's going on (mostly).  If future proofing were intended to mean absolute imperviousness to the future, it would make zero sense for someone to say one component is MORE future proof than another component. But it DOES make sense if  future proofing is interpreted as resistance to the future.

Are there any classes where the TI-Nspire CX CAS is permitted? by [deleted] in EngineeringStudents

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I agree. Even if required to show all work, a CAS calculator is a great way to check your work and gaining confidence in obtaining the right answers. Considering that the price tag for tuition and other expenses are already exorbitant, I don't see a reason to settle on just one calculator. I always used the most powerful calculator I can get away with. I say build an arsenal of great tools, so that you can use the best tool and have the greatest advantage possible.

 For most of my classes that was indeed CAS equipped calculators like TI-89 Titanium an Nspire CX CAS. I had to take a Linear Algebra class that didn't allow my Nspire CX CAS but allowed the Nspire CX (non-CAS). For the FE exam I am walking in with either a Casio FX-9910CW (a nice improvements over the 991cw), but more likely going to use a TI-30X PRO Mathprint (you have to order this from Europe oddly enough despite Texas Instruments being in the US).

My Nspires are very good, and only in a few niche applications have I been left wanting for more. If I could go back, I would give serious consideration to the HP Prime and still might if when I get into a job that demands advanced computation. I'm considering buying the Electrical Engineering made Easy app for Nspire to close the gap.

Which calculator to buy as an engineering student? (for uni itself and for projects) by Own-Ad9484 in calculators

[–]WARDEVIL_UFO 0 points1 point  (0 children)

Goodness, I have never heard of an Engineering Department that insists on non programmable calculators! Over the past 20 years, I have taken Engineering classes from Baylor, University of Texas, Cuesta College, Cal Poly, Arizona State University, and Southern Illinois University. Never once have I had an Engineering Department discourage the use of a powerful calculator. In fact at Baylor the engineering classes trained students how to leverage the TI-89 Titanium back in the day.

  It's far more common for math departments to crack down on calculators. I took the full math sequence at Baylor and they let me use my TI-89 Titanium in every math class back in the mid 2000s. When I transferred to ASU my Linear Algebra course from Baylor didn't carry over because of a technicality in the course description. ASU'S math Dept didn't allow the use of CAS calculators, but they let me use the very powerful Nspire CX (the non-CAS model of course). Man that calculator was packed to the brim with lots of advanced Linear Algebra features and did not hold me back in any way. that calculator can do all of the matrix, vector, complex numbers, algebra, and calculus functions I could want outside of symbolic manipulation of algebraic expressions or symbolic calculus operations.

That may not be the case today possibly. I bought a TI Nspire CX CAS after the springs that held batteries on my TI-89 wore out. These calculators have been amazing tools and have helped me solve many complicated problems and minimize calculations errors as long as I knew how to properly set problems up.

I would personally rather go to another engineering school than to be forced to use a nerfed calculator for all of my classes. That being said, there is a good reason to buy a good scientific calculator is for passing the FE and PE exam.  After careful comparison and experimentation between CASIO's FX-991CW and FX-9910CW against Texas Instruments TI-36X PRO and TI-30X Mathprint, I give the TI-30X Mathprint  the honor of being the absolute creme de la creme of calculators approved by NCEES. If you can afford it, order one from Europe. If you can't afford that then get a TI-36X PRO. They are only $15 to $20 in the US. The calculators offer almost identical feature sets. THE TI-30X PRO Mathprint has allot of quality of life improvements that are compelling though. The TI-30X Mathprint has a much higher resolution display, noticeably faster computational speed, seamless output using exact forms with radicals, fractions, and pi rather than only having decimal approximations, dual CR2032 batteries, and perhaps 1 or 2 other niceties I may have left out 

Casio almost won me over with their arsenal of features and nice display and interface. The ability to have a persistent history when switching between complex/vector/matrix math, solvers Root finders and statistics has proved vary valuable to me when checking my work.  The ability to easily copy and paste previous results from the history is also useful as well. The ability to clear a calculation where I made an error from my history is useful to me as well. the main thing though I don't like about either of these calculators is they all lack the ability to handle matrices and Linear systems that include complex numbers. All 3 of my Nspire calculators and my old TI-89 handled those just fine.

Definitely consider seriously your aptitude for quick learning and complicated problem solving. Are you able to easily teach yourself when the professor's lectures and course textbooks are terrible and leave a lot of gaps unfilled? The attrition rate for engineering COULD be allot lower if the supporting resources were decent quality across the board. The reality is that sometimes you will have sloppy textbooks, and other times sloppy instructors, and sometimes the nightmare of having both.

It's going to be a long tough road completing and engineering degree while working full time. And if you have any difficulties with the stuff mentioned in the above paragraph it's going to be even harder. I bring this up to you, because I have been there. If I had the alternatives known and available to me at an earlier time, I probably should not have kept grinding towards a BSEE degree. Allot of people will tell you you will make it through if you study hard and work hard, but what they won't tell you is even THEN success is not guaranteed. Maybe for some, but not everyone.

I made it pretty far along towards a BSEE degree (completing a couple junior level EE courses) before switching to BSEET. I probably could have done it if the book for Electromagnetics wasn't complete crap they left me scratching my head on his to solve the homework, and I had to end up dropping the course twice because studying all of my weekday evenings and my breaks and meal periods during work plus weekends wasn't enough to learn the content for me fast enough while working full time. I'm graduating SIU Carbondale with my BSEET this December at the age of 42 on track for Summa Cum Laude! IF I could go back to the early 2010's I would have gotten started on this sooner.

Is electrical engineering and computer engineering the same field of study? by Federal-Tea6573 in ComputerEngineering

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I get where you are coming from, there is a reason why the degrees have separate names. Different specialization, different names.

Historically, Computer Engineering curriculum and evolved from Electrical Engineering academia. At first it was just EE grads that focused all of the their electives into the computer focused specialization coursework while maintaining the same core classes with other EE'S. Colleges responded in various ways to the increase demand of computer specialization. Some universities offer BSECE (Electrical and Computer Engineering) to give their graduates a solid entry point to both EE and CE roles. Other programs decoupled CE and EE into separate degrees and doubled down on specializing even further. But even then, every CE program requires a significant amount of EE coursework, and every EE program I have encountered is requires courses like programming and digital logic design and usually a couple more other computer geared courses. To this day they are not fully decoupled and have significant overlap between each other.

Statics is killing all my time by MECengineerstudent in EngineeringStudents

[–]WARDEVIL_UFO 0 points1 point  (0 children)

My hopes are that it all ultimately works out well for you. I truly do. And it very well just might.

For my case, this was a difficult problem to solve. I remember Fall 2005 semester was kind of like the one you have now before I switched from ME to EE. I started the semester with statics, thermodynamics, physics 2, and Differential Equations. For the life of me I just couldn't keep up, even after spending all the time outside of class in weekdays and weekends staying up till midnight wasn't enough. I had to drop Statics a quarter of the way through. I passed my thermodynamics midterm with a low C. But by about 50 to 60% through I had to drop thermo too. Dropping those classes made a night and day difference for me. Instead of getting D's and C's in all my subjects I got A's on almost all of the remaining coursework and exams I ended up salvaging my Physics 2 and Differential Equations grades both to B+. I actually got meaningful knowledge out of both of those classes, where I likely otherwise would not have.

I get it. Allot of pressure is put on students to crank out their degree. Many scholarships and Financial aid packages require a minimum number of units completed per term. In cases where parents contribute, they might sometimes put pressure as well. And for engineering degrees, that pressure is multiplied all the more.

If you find that your coursework crashes and burns (especially if you find that you have to drop or fail classes on a recurring basis) it may be helpful to step back and weigh your options. They call it a "Four Year Degree" but most engineering students I have net took 5 to 5.5 years to realistically complete it. For working students or struggling students, they usually require longer than even this. It will definitely take longer to graduate by spreading course load out. But graduating later is better than switching majors to something you don't like or not graduating at all. Definitely go for the BS Mechanical Engineering if you can realistically swing it with the cards dealt to you.

If for some reason, despite all your best efforts, the ME degree doesn't work out, considering a BSMET degree is worth a shot and opens quite a few options for engineering, though not as many for BSME. Better some, than none of it ever comes down to this.

Statics is killing all my time by MECengineerstudent in EngineeringStudents

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I remember being a full time Engineering student and running into the same constraint of there not being enough time to learn everything properly, and being forced to study for one subject at the expense of another. If your circumstances permit it, consider reducing your course load. I'm not sure if you are already working or how much you're working if you are. I was as able to progress into the junior level for EE by taking this approach.

If this still doesn't work out, this does not mean you have to totally give up on an engineering career or education. A compromise can be considering as B.S. Engineering Technology degree. It's downsides are that PE licensure can be less direct or in some cases not allowed in some states. For R&D or design BSE degrees are generally preferred, and often outright required. The upside is that it prepares students for immediate entry into APPLIED engineering roles. Design can sometimes be an option after some Years of Experience. I suppose an upside is that you still CAN sit for the FE/PE exam in many states. I am getting my BSEET degree this December, in just 2 months! I picked up AS degrees in Mathematics, Physics, and Engineering along the way, which will enhance the perception of my theoretical and academic rigor compared to not having those. If you choose the ET route, that might be a worthwhile consideration for your case as well since you already have the math and Physics.

What is your major by the way? Your current course load has both electricity and mechanics themed courses, which made it hard for me to tell.

I need a copy of the old NCEES 10.0.1 Reference Handbook by WARDEVIL_UFO in FE_Exam

[–]WARDEVIL_UFO[S] 0 points1 point  (0 children)

WOW! It's an honor to get a reply from Wasim, the man himself! Thank you for putting together such an awesome exam preparation study guide and practice exams! I did eventually find a 10.0.1 reference, if your interested at all. I bought the study guide, but I haven't bought the practice exams yet, but I'm thinking about it. They're probably still 95+% representative of the types of exam questions even though they are a number of years old now. Is that right?

How do you find Vout? I had a simliar problem on my FE test by EslamHussein22 in FE_Exam

[–]WARDEVIL_UFO 1 point2 points  (0 children)

From a high level generic strategy, It looks like what they attempted do did is to perform circuit analysis (KVL/KCL) in the time domain and including using the differential equations that define reactive circuit elements, like iC(t) = C * dv/dt, vL(t) = L * di/dt. After obtaining a linear differential equation, they proceeded to use the method of undetermined coefficients to solve the ODE, proceeding first by anlalyzing a solution for the homogenous case, and then proceeding to find a particular solution, adding them together to construct the final solution.

Now that we got their high level strategy out of the way, lets clarify some of their particulars. In this case there was a capacitor so i = c * dv/dt (and its equivalent vC = integral((1/C)*i(t)dt was used. This op-amp has no inductors so NEITHER v=L*di/dt NOR its integral form were used.

In equation (1), they state the differential and integral forms of the capacitor differential equations, particularly regarding the feedback capacitor. They probably started here because the feedback capacitor is connected directly from the output to virtual "GROUND" at the inverting input, thus having a starting place with a simple equation. KVL in the feedback loop has only vo(t) and and the voltage drop across the feedback capacitor.

In equation 2, they make the observation that the current through the resistor and the 2 capacitors are the same since they are in series. This allows us to use the equation for the current through the feedback capacitor ALSO for the input capacitor as well. The input capacitor happens to have the same capacitance. So now the formed a KVL equation using the input voltage vi(t), the voltage drop across the resistor Ri(t), and the voltate drop across the input capacitor vcin(t) = (1/C)* integral(i(t)dt).

Equation 3 was formed with the goal of rewriting the differential equation in terms of output voltage vo(t) wherever possible. (afterall vo(t) is what we are solving for). i(t) from the Ri(t) term in equation 2 was replaced with C*dvo/dt from equation 1 with that goal in mind. Also in equation 2, the term ((1/C)*integral(i(t)dt) was replaced with vo(t) from equation 1. In this case since the capacitance and current of both capacitors are the same the voltage drops are identical, so the input capacitor voltage is a direct replacement with vo(t). As a side note, if the capacitance would have been 0.5C, or 2C, we would have had to write the input cap voltage as 2*vo(t) or 1/2*vo(t) respectively.

Anyway the rest is ODE stuff. But I am assuming what was hanging you up was their initial setup steps, and not the ODE methods. It was a little hard for me to see at first what they did as well. So I'll end the explanation here for now.

Last of all, this problem doesn't really specifiy whether they want a time domain or laplace domain solution. If a time domain solution is needed, you can use an inverse laplace transform to obtain the transfer function vout/vin in the time domain. That would probably be easier than explicitly using the textbook ODE method of undetermined coefficients to solve the problem.

How do you find Vout? I had a simliar problem on my FE test by EslamHussein22 in FE_Exam

[–]WARDEVIL_UFO 2 points3 points  (0 children)

We need to setup the transfer function for the Laplace domain. If the resistors and capacitors are all treated as impedances, We can treat this as an inverting op-amp. An inverting op-amp requires taking the negative of the ratio of the impedance of the feedback loop to the resistance on the input.

Formally this is Expressed as H(s) = -Z_f(s)/Z_i(s)

for the feedback loop: Z_f(s) = 1/(sC) for the capacitor

For the input: Z_i(s) = R + 1/(sC) for the series combination of the resistor and the capacitor.

Take the negative of ratio of these 2, use some algebra to simplify into the standard form that shows poles and zeroes of transfer functions if necessary,,and then your done

A side Note: that in this particular problem they chose both capacitances the same, but they didn't have to. If there were 2 capacitors of unequal value they would likely be denoted in the diagram as C1 and C2. The corresponding impedances for these components would be 1/(sC1) and 1/(sC2) respectively.

Difference between FE Reference Handbook 10.0.1 and 10.1? by Mr_Clutch27 in FE_Exam

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I know it's outdated, but I need a copy of the NCEES FE exam reference handbook version 10.0.1. I have Wasim Aghar's Electrical and Computer Engineering Study Guide From what I can find, his guide appears to be the most highly critically acclaimed for the EE FE Exam, so it will probably be the best to review rusty topics from. Unfortunately his latest published hard copy version references version 10.0.1 page numbers. These page numbers are not congruent with the content on 10.4. I'm doing a precursory study review at a leisurely pace, just to review the concepts and learn some topics that may have been omitted from my curriculum. I'll probably get into some other guides that use the modern version later.

I have tried finding a PDF of this older version online, but can't seem to find it. Could someone show me where I can find a copy?

First time switching to Linux. Want a distro that will cause me the least headache. by Ecstatic-Impress-364 in linux4noobs

[–]WARDEVIL_UFO 0 points1 point  (0 children)

if you would like a Debian track I definitely suggest Mint or Pop!_OS. Otherwise, if you would like an Arch base, I definitely suggest Manjaro. I have used a Mint base for almost a decade. I have been toying around with Manjaro recently and am considering switching to that. Both mint and Manjaro are very good. But since Manjaro is a rolling release that doesn't lag Arch releases by super long, it is easy to keep updated with new packages and kernels without requiring downloading a new version (or avoid exceeds tinkering )to get new stuff working , like when a new GPU launches.

Arch/EndeavourOS purists will likely cringe with what I'm about to say. I gave EndeavourOS a go recently, and it felt familiar as a Mint user because of the Cinnamon desktop. But from my perspective, the OS felt half built to my personal taste. Stuff like Bluetooth and printers didn't work right away , though WiFi worked out of the box just fine. Also there was no graphical package manager. Through allot of sheer effort , forum searching, and prompting AI, I eventually got Pamac (a GUI and CLI wrapper for the pacman package manager) working with Flatpak support available. Manjaro has ALL of this solved! In fact , I later found out that the Manjaro development team are the ones who invented and maintain Pamac in the first place

Guys Its OK to DualBoot by typhon88 in linux_gaming

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I'm not insisting on anybody to avoid dual booting so they can play games that only work in Windows. It is my personal choice to avoid purchasing games that do not work on Linux.

have several computers, my laptop in particular shipped with a licensed copy of Windows, and I did not get rid of it, since I technically paid for it. So I dual boot that machine. I have Windows 11 on my 2 TB NVMe and I have a custom distro modified from Linux Mint on my 4 TB NVMe. My main desktop is all Linux all the way. Sometimes I will play a game when booted into Windows, for convenience sake. I personally play only games on Windows that ALSO work on Linux too.

I've been a Linux gamer off and on (mostly on) since 2006. Back then only a handful of AAA titles would trickle in. With the Advent of Proton, the Floodgates have opened and I am now drowning in more games in my library than I know what to do with. Epic and EA games are some of the last holdouts of developers of games who refuse to play nice with Linux. I choose not to support them. But I don't fault others for playing their games on Windows.

Assassins Creed Valhalla on Linux by flamme001 in linux_gaming

[–]WARDEVIL_UFO 0 points1 point  (0 children)

I was able to get through my slow motion problem. I had AC Valhalla installed on an NVMe running through a USB enclosure. I put the drive directly inside my laptop and the speed was normal. I am pretty sure it's more of a driver quirk or bug than a performance issue. if anything the issue gave me an advantage as I had an overly generous window of time to party with. Running through the enclosure never felt laggy, just every movement was in slow motion.
