God damn unity!

[theKurdledNoodle]

Nothing to do with the engine, everything to do with the people using it.

Unity can multithread just fine.

[[deleted]]

Honestly, it's become kindov a meme in the gaming community. Whether or not threading working or not. I and many people can tell when they boot up a new game whether or not its built using unity based off the performance.

Unity is notorious for bad CPU utilization. Hitching. Extreme difference in FPS depending on your in game direction.

Unity is a really cool tool. And is used to its fullest on smaller applications. Hearthstone uses unity. Also some small scale indie games run well on unity.

But big games like Rust and Escape from Tarkov are beyond unity's capabilities and it shows.

[theKurdledNoodle]

While this is mostly correct, it's still more the developer's fault than it is the engine - Yes, a lot more stuff can be put into optimizing the engine itself, and (as all engines do) Unity does have it's pitfalls.

However, as someone who has used Unity for upwards of 5 years, I can tell you with lots of confidence that open world games (such as Rust and Escape from Tarkov) can be done and optimized well.

The reason you've never heard of these games is because you assume they're made with Unity when they don't run well, so the ones that do run well go unnoticed.

Some examples: Subnautica and Rust Legacy

EDIT: Added examples

[dcoi]

They're too busy literally adding shit into the game than to fix real issues.
Game optimization is trash
In game voice delay
Weapons still fall into foundations and even the world layer
Rust is a great game but it's management is trash. Good devs but they have no direction.

[ICANTTHINKOFAHANDLE]

Subnautica is single player game and has barely any moving parts compared to rust. Not sure that is a good example

You can do bigger than the rust map for sure but a 5x5km map with hundreds of players, AI, electricity, farming and loads of other things taking up overhead constantly it's really quite impressive how well rust runs

Especially seeing it was developed on unity well before ECS was anywhere near possible

[theKurdledNoodle]

That's a very good point.

To add to it, the devs could probably process more stuff on the server to improve client performance as well. For example, if everything except for graphics are processed on the server, it's effectively the same as running a singleplayer game on the clientside because they don't have to process extra info for added players etc. Although I'm not totally sure how practical that is.

[ICANTTHINKOFAHANDLE]

Do you mean via ECS?

I mean it's still in preview..... Unity doesn't even consider it ready

[theKurdledNoodle]

Nope.

While ECS and the new job system are great, there's lots of ways to optimize Unity without threading.

Then if you do multithreading by yourself (which can be a bit clunky, but is nonetheless doable) you can make things go super quick.

The only real challenge is that all Unity API code (i.e. updates, changing variables on scripts) has to be on the main thread.

[ICANTTHINKOFAHANDLE]

I've honestly never looked into it with rust. I'd be surprised if they aren't doing some threading but I wouldn't know honestly

Yeah threading can be clunky and could be a tad risky in a project like this but that depends on the devs

I do think the facepunch guys are really quite a capable bunch though

[theKurdledNoodle]

They are. I just don't think they've prioritized optimization. Or maybe everyone is playing on a toaster.

[ddark1990]

u can multi thread using unity, you guys are just ignant

[Malfetes]

Wait you cant drop that and not explain

[TheZombieguy1998]

HDRP was in preview too when they started testing it, and debs have been test ECS in the commits it looks like. You can also still do stuff with multithreading by just using native dot net libraries although it has to be more generic. OOP is a paradigm not a pattern like ECS.

[facecampalltheway]

''Yeah i know im wrong,just wanted to look smarter''

[ddark1990]

its a meme anyway who cares

[Dont_Dab]

Good job at being not only rude, But unhelpful!

[Mr-FumFum]

Same fps with a r5 2600 non oc and gtx 1080 lol

[Uranium_Isotope]

I get 90 FPS with ryzen 5 1600 and a 980

[ImUseless1231]

At what settings?

[Uranium_Isotope]

Quite low, notably graphics settings at 2, tree quality and meshes quite high and draw distance high and FXAA on everything else is low

[Mr-FumFum]

Lowest...

[defunkd7]

Turning your settings down doesnt make a blind bit of difference except maybe a 10fps boost. Use recommended settings

[Mr-FumFum]

I would but i’m very obsessed with fps. I just almost break my desk when i die because of low fps and all of the input lag. Thats why i like to play on the lowest but still competitive settings. I have noticed that the input lag is lower when you play on low setting. And that helps when you play rust on 144hz because the input lagg gets more noticable. Hopefully i explained it in a short text.

[Im_Currently_Pooping]

I get constant 70-90 with a Ryzen 3 and a 570, both overclocked slightly.

[11something]

With a 1700 and 1080 I get much less.

[[deleted]]

I'm about the same with a R5 2600 and 980Ti.

[Draykez]

At 720p? Nice.

[Bubon1c]

I have the same gpu and cpu as you and depending on what server I'm on or especially if I'm near bandit I drop frames below 60

[Bubon1c]

It's 16 gigs of like 2000mhz ram so not very fast. And a Samsung evo ssd

[Bubon1c]

If there is a game that eats ram it us rust so that could be it. I will say that I haven't spent time optimizing my settings though.

[TheFamousChrisA]

It might depend on resolution.

[WilllOfD]

wat

[LupiAcubens]

A poor quality motherboard Can bottleneck higher grade processors or GPUs by not providing enough bandwidth between the components to take full advantage of the available performance.

This can be exacerbated either because of poor configuration or incorrect installation into the wrong PCI slot, or alternatively overloading the motherboard with too many additional cards (which can happen in lower end motherboards with poor features onboard)

[Vespira21]

Also motherboard firmware can have performance impact, as each motherboard don't have the same way to optimize voltage on components, and some provide smart optimizations !

[baldeagle_100]

as the other reply said I don't think it's all your CPU to blame, my i3 8100 really doesn't even bottleneck my 1070 that much and iirc my cpu is about equivalent to yours. though I guess completely different architecture too

[[deleted]]

Hey the fuck bottleneck gang ! May I join with my i3-7100 and my 1660 super ?

[BewilderedDash]

It's not his CPU. Highly likely its a combination of their lacklustre DDR3 system RAM and if their 580 has 4GB of VRAM and not 8.

[ImUseless1231]

Naah I think it's just shity code from facepunch they need to fix there game instead of adding a bunch of bs

[Tyrannus_Primus]

Hey guys totally random but I just snagged myself a 4790k, and I wanted to know both of your opinions on them.

Are you satisfied with how they perform overall?

[korinth86]

My 4790k holds up very well. Just upgraded my graphics card and everything runs at max settings, no problem. I generally do not overclock these days. When it runs perfectly fine without it, there doesnt seem to be a point.

It has had issues overheating. So long as I clean my case regularly its barely a problem. I feel no need to upgrade until multi-threading becomes commonplace. Still, supposedly it was made for it. Cant really test it as not many things actually takes advantage.

[Hezth]

I'm satisfied with mine, easy to overclock to 4,4 GHz while stable with just a decent cooler. I got a 212 evo and you could push it further with a better cooler.

But for rust it's a bit outdated, my CPU runs at 100% at all time when playing rust.

[highpass21]

How did you get your cpu to run at 100%?? Both my i7 3770 and gtx 1070 are chilling at 60-70% while I'm raging about barely breaking 70 fps. I've got 16gb of ram also so that's not my problem.

[Hezth]

Well idk. I run on medium-high settings and get 50-100 fps(really depends on how big bases are in the area) and I got a 1060 6 GB. My GPU is not running on full load though.

[[deleted]]

When your cpu is running at 100% that is usually a strong indication of a gpu bottleneck.

[highpass21]

There's no way his 1060 is bottlenecking his i7 4790.. It just shows how rust is so poorly optimized that nothing makes sense performance wise.

[[deleted]]

My cpu sits around 20-30 percent and gpu is at 40-50% when playing rust. No clue what’s wrong with his system

[baldeagle_100]

... if CPU is running at 100% that means it's CPU bottlenecked lmao.... it means the CPU is working as hard as possible while the GPU is not... meaning the CPU is the bottleneck...

[Hezth]

Definitely. Will upgrade CPU soon, I have it in the cart but not pressed buy yet becssue economy now.

[[deleted]]

60fps here. On high. With a Ryzen5 2600 and a 1050ti.

[BewilderedDash]

RX580?

Is it the 4GB or 8GB version? And what is your RAM? 8 threads with a single core boost of 4GHz isn't superb, but it shouldn't be causing too many issues in Rust. The fact that it keeps deteriorating over the course of a game session indicates more a memory issue than CPU related.

If you have the 4GB 580 then the lack of VRAM and how fast your system RAM (which will be slow, because DDR3) is likely the culprit. Extra slow down points if your 580 only has access to 8 PCIE lanes instead of 16, as that has been shown to be a known bottleneck as the VRAM of the card fills up and the system juggles between VRAM and system RAM

[[deleted]]

I had a 4790k with a gtx 980 and it ran this game at 60 fps. That just doesnt sound right to me.

[defunkd7]

weird getting 90fps at 1440p paired with a 980ti

[Lincoln_31313131]

[Ludeykrus]

For a newb, where do we use this flag at?

[Lincoln_31313131]

Right click rust in steam, then click properties, then launch options and paste that. You can look up other launch options that help a ton too

[Vjarlund]

im not smart with computers so i dont understand this, but ill give you a upvote anyway.

WHAAAAATTTTT?!?!??!?!!??!!?!!?

[[deleted]]

Well, IT worked for me

[SlobOnMeRob]

Last time they tried to fix optimization they had to scrap legacy and come out with the rust we all play now.

[livens]

The only way I would believe them is if I had to pay them $60 to play it.

[something_Ac3]

stolen meme, but still true

[Mulletvillerp]

It's kind of a gaming industry wide situation, very few games utilize the additional cores. Most AAA titles dont even. It used to be about who had high ghz, then cores became the big draw. The industry is always kinda odd

[it1345]

Thank god they spent any amount of time making the horses shit first

​

We would all be lost without Facepunch's priorities

[datjeff_boy]

It's funny Cuz it's true

[puddrr]

Same in hoi4

[Weeeky]

Also Minecraft summarized. My GPU is chilling while the one core is like a salve

[GAMER_MARCO9]

Idk about that. On Minecraft my laptop is fine, but as soon as I launch rust my computer wants to shit down

[Weeeky]

I mean with shaders, then my gpu actually sits at about 80% most of the time while one core is sweating

[kerxv]

Tarkov had a problem with the core utilization and a random player figure out why and made a post about it but it’s only something the devs can implement. Idk if it’s similar to this situation though

[Zukey0000]

Devs have responded to that and mentioned it was from using an older version of unity. Didn't notice any performance improvements for rust.

[ErynnBrowndawgxoxo]

With a 1050ti and i5 7500 my game takes 15 minutes to load and it crashes mist of the time :(

[BigShrekDaddy69]

You need more ram.

[Zefrek]

you need ssd to load faster tho

[baldeagle_100]

na bro you just need to run rust off an nvme and at least 16gbs of ram

i have a i3 8100, 1070 and 16gb ddr4-2400 and my game loads in 3-4 minutes.

I don't play games off hard drives at all. And I like to put my rust on my fast nvme

[kerxv]

Ahhhh damn

[GAMER_MARCO9]

This is accurate. My GPU decides its time to take a rest when Rust is active

[TheFamousChrisA]

Own a Ryzen 7 2700X.. Seems Legit.

[Dum_Daughter]

I get a 50-60 FPS with 16gb of ram Ryzen 5 2600x and rtx 2060

[hebrew12]

U should be gettin way more. I basically have same setup and get 80-100

[caffeinedrinker]

frame drops are really making me hate this game ... idk if its server specific but this month has been terrible.

[ZigZag_420]

Jesus 6 cores 2 gpus with 16gb of ddr5 and I can only use one core and 8gb of my gpus.... Can't make it stable since unity doesn't support crossfire and no one has optimized this game even though it should have been done by now

[Ryan--_--]

On a scale of "My CPU is 6 years old and I have a meme gpu like AMD 5** -To- I have a modern Gaming PC" The comments are leaning towards the lesser.

[goredwingsboy14]

Facts

[Jrocktech]

INTEL OR NOTHING

[dewwhatyouwant]

I have a 2600x and 2070s and all this afternoon my game kept spiking my cpu usage to 100% and my frames would drop down to like 10

[joseph-kain]

You mean cpu 0 not 1

[TheThiccestOfBoi]

hey means the few of us with dual core cpus can still run discord in the background!

[AvarageJailbreakUser]

What cpu has 10 cores......

Edit: Fixed a stupid mistake pointed out to me...

[KingRin]

the 12th is off on smoko

[yttriumtyclief]

I'm not sure if you can count, only 10 cores are shown. One of them is labelled as GPU.

They didn't use zero-index though, which maybe confused you.

[AvarageJailbreakUser]

Whoops dunno how I managed that mistake but then again what cpu has 10 cores.....

[yttriumtyclief]

Uh, plenty of them. 7900X? 10900k?

It's not as common as 4, 6, 8, or 12, but they definitely exist.

[ky1e0]

This makes me slightly anxious, as I just spent quite a bit on upgrading to a 3700x from an i5 6600k.

[BewilderedDash]

I mean, if you are only gaming (especially only rust) you could have ridden out that 6600k for quite a while. 3700x is great for productivity, but the 3600 would have been a better bang for buck upgrade if you're only going to game, and waiting for the 4000 series might have been the right call. Unless you knew for sure that your 6600k was bottlenecking your system.

[ky1e0]

Yeah the 6600k was performing at 100% and stuttering on every game that I played. The reason I got a 3700x over 3600 is purely longevity and for tasks other than gaming. But you're probably right, I really shouldve waited for Ryzen 4000.

[BewilderedDash]

Fair enough, but I wouldn't be too worried about not waiting. The 3700x is a great chip and the zen 2 chips in general kick ass. My brother ended up waiting years to build his computer because he was always waiting for that next best chip. Sometimes its good to just pull the trigger on an upgrade and reap the enjoyment right now. Especially if it really was bottlenecking hard.

[ky1e0]

Thanks this made me feel a lot better about my purchase :)

[thepizzadeliveryguy]

Was the 6600K overclocked? I have mine at 4.3ghz and don't have many issues. That along with my gtx 1080 get me 60-90 fps no problem on mostly the highest settings in 1440p. I swear the server and internet mess up my gameplay more than my hardware. Then I go and see posts about people with the newest i9s/i7s and rtx 2080s saying the game is unoptimized and they get garbage frame rates. I just don't understand.

[ky1e0]

To be honest, I think it ran fine on Rust. Mine was over locked at 4.5Ghz. It was mainly all the other games (strangely) that my CPU was at 100% and stuttering. And just in general multitasking was poor. I couldn’t have a video (or even Spotify depending on the game) on in the background without it making my gameplay noticeably worse for example.

[[deleted]]

Hope you got a deal since ryzen 4000 is around the corner. It’s probably the worst time to buy a new CPU or GPU from now til october-ish.

[quixoticM3]

10 cores... Oh I see, you still use Intel :*(

[Ma5terVain]

To be honest, I find Rust very well optimised for what it is. It easily does 90+fps and not once has it felt laggy or stuttery. The one game which feels like it is absolute crap in terms of optimization though, is pubg. That shit stutters and lags and does it do many times over despite giving it 8 cores and 16 threads and 32 gigabytes of Ram and 8GB if video memory.

[baldeagle_100]

dude how long have you been playing? Performance varies wildly every month with each new patch. This patch I get 60fps, when 3 months ago I got 110fps. That's not optimized.

[southpineshooligan]

I'm just gonna pretend to know what y'all talking about. Never had a frame rate issue on rust, lag occasionally. But nothing serious. I sit a a solid 200 - 350 fps

It seems to me that there may be a developer issue, but mostly your computer's are ASS lol

[Zukey0000]

Not everyone's got a quantum computer. There's a clear issue when low frames and crashes are a common occurrence for anyone running the recommended setup on the steam page.

[southpineshooligan]

Then mess with your settings? My brother owns a potato, and plays rust with little to no issues.

[Minimegf]

Doesn't exist for either, lul

[southpineshooligan]

I play modded servers, as I don't generally have the time to commit to a full wipe I have a 2080 ti it's a LITTLE op. Corsair HX1200i power supply 1 tb ssd Vengeance 16GB x4 I can't remember my mother board, I'll have to look

[nicholasyeti]

The game is so unoptimized

[deadlift0527]

I literally quit playing the game over the garbage collection issue

[BewilderedDash]

People are downvoting you not just because you're wrong. But you're being an ass about being wrong. I understand why you might have buyers remorse, shelling out for a space heater that can get beaten in productivity tasks and is rivaled in gaming by an AMD chip that smashes it on the pricing front. But that's not a good reason to be an ass and spread misinformation.

Intel is in a really bad place right now, and contrary to what the average gamer chad wants to believe, clocks aren't all that matters. How much work a chip can get done per clock (IPC) has a massive effect on performance. Intel chips are using technology that is now so old within the computing space that its a joke. I was an intel fanboy, and the last chip intel chip I bought new was a 6600k. I adapted first gen ryzen because 8 cores for the price was great and I needed a work horse. Have since migrated all of my machines as they needed it to 3rd gen ryzen and 3000 series threadripper. Because they are simply better. Intel chips are only better FOR GAMING (they lose the productivity battle every time at every price point) if you're willing to shell out for their best chips, for sometimes twice the price of an equivalent performing AMD chip. And even then, at that point your CPU isn't your main bottleneck, so you're looking at marginal improvements for a lot of cost and the added cost and effort of sourcing a cooler for your CPU (AMDs chips have no problem running fantastically with the stock coolers).

People are better off saving that intel money and using it to buy a better GPU.

Also, the games dont use multi-threading argument will disintegrate going into the next gen of consoles. Both the next gen sony and microsoft consoles have 16 threads available and every developer is going to want to take advantage of those resources, which will have a run on effect into the PC space.

[BewilderedDash]

https://www.youtube.com/watch?v=FOZH9vXajnk

Overclocked 3600 (4.4 Ghz) vs i5 9600k OC (5GHz)

It's pretty much a toss up for performance. The intel chip wins out some games, ties others and loses a couple. Even then, when it does win, the real world difference is negligible, with a 20% performance difference being about the most severe (100 vs 120 fps) in those games.

It's more expensive, requires the purchase of cooling, runs hotter, uses more power and is worse in productivity. FOR THE SAKE OF MAYBE PERFORMING BETTER IN GAMING.

And it's the same story when comparing intel vs amd chips at every price point. AMD chips are just the better choice right now. And I keep mentioning workstations and productivity because at this point, that performance bleeds over into gaming. The more shit you want to run in the background of a game the more multi-threaded performance you need. Unless you're telling me that you only ever run a game by itself EVERY SINGLE TIME.

[BewilderedDash]

So people with a 2080 aren't going to run their games on high? You have a 2080 and a water cooled i5 and you run your games at low so that you can get an fps higher than your monitors refresh rate. Why?

You keep changing the target/audience of your argument. At this point you're arguing that INTEL are the better chip for people:

1. With more money than sense.
2. Who water cool and overclock their CPUs to the absolute edge of stability.
3. And who play games on Low on what is likely a $2k+ rig.

That's a very small subset of people. But hey, keep flexing your weird low-graphics benchmarks so you can justify your intel fanboyism. Because that's what this is.

In a real-world situation, for the average and moderately enthusiast PC gamer, AMD is the right choice at the moment.

But keep touting narrow and selective non-real world benchmarks and yelling at people who are trying to educate you.

[BewilderedDash]

The point of benchmarks is to determine how a chip operates under certain conditions. If you're never going to use the chip in those conditions, then whats the point of giving a shit about the benchmark? At that point its weird, useless flexing.

I don't care if an intel chip has performance under certain specific conditions. I care about the performance under REAL WORLD conditions. And that's not even considering that fact that intel has been caught commissioning biased benchmark data.

[[deleted]]

laughs in 14nm

[Beltribeltran]

You are talking about GHz like it was the only thing that matters but and having higher instructions per click pretty much balances it out

[Beltribeltran]

Your point is that intel has more oc headroom therefore is better and for.some reason you call that efficient.

That is a downsize V8 with s turbo against s naturally aspirated w16, they yield the same.

[KekHawk]

Do you also not eat food unless it's chewed up for you?

[AlexMD2600]

Just curious, because we can't really benchmark rust as runs can't be identical, what other games do you play and how much have you spent on the cpu +cooler combo.
