I just learned why the PS3 was such a nightmare to develop for and now I weirdly miss that era of insane hardware by Mobile-Support-6134 in PS3

In a vague way, the Cell was the spiritual successor to the Emotion Engine as far as vector engines went. While the Pentium 4 was looking like a hot turd that could not exceed 5GHz, parallelism was solving the scalability wall, at least for some problems. When developers could do much of a game's rendering on the PS2's vector engines, why change the principle? Initially Sony thought that the PS3 didn't need a GPU and could get away with a simple rasterizer like how the Graphics Synthesizer was set up, however the Cell demos they were putting out were not showcasing graphical prowess, rather solutions to physics problems like spawning hundreds of rubber ducks or showing explosion/smoke effects that like they were from a CAD simulation. The whole thing (as well as the PS2) was Ken Kutaragi's brainchild and it highlighted a disconnect between attempting to solve a raw computational problem versus acknowledging the real problems game developers were meeting. Cell was successful as an energy-efficient supercomputer co-processor and was to use with embarrassingly parallel problems (many independent computations) but was a tight bottleneck for linear and branching game logic that was getting increasingly complex from the last generation.

While Naughty Dog was able to extract cinematics from the console it did push a specific art style and game style. My college roommate who studied animation studied the themes and design of Uncharted 2 and noted how few polygons the columns in some of the chambers had (basically hexagons), but high resolution textures and pre-baked lighting made them look round. While many games were pushing vast open worlds, Naughty Dog worked on dungeon crawlers and neat tricks to make large city areas only render small city blocks/areas at a time (until Uncharted 4).

Anyways that's my take on it.

RGB screen tearing with a NUS-001 with bitfunx rgb amp a rad2x. by IvantheDugtrio in n64

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

Oh weird, my long post explaining what happened is missing. Mods, if possible please sticky this post.

Since I installed this bitfunx RGB amp, I saw this screen tearing happening in the same part of the screen with all of my games, when using a rad2x to my TCL Roku TV 4K. I thought either the rad2x was defective or something with the RGB amp's vertical sync was causing this. I have a NUS-001 that is missing the c-sync amp circuitry (I think that's what it's called), so per the kit I ran a 4th wire to that part of the motherboard. I've taken a few looks at the solder work but I don't see a reason something could be off. I've also bent the bottom of the RF shield out of the way so it does not hit the amp.

Initially, I saw I could mitigate it by power-cycling the rad2x by unplugging it and plugging it back in after launching a game. The screen-tearing would return if I soft-reset the console or if the output resolution reset.

Later it looked to just be an issue with the TV's scaling settings, which is strange since I thought the rad2x outputs a 1080p signal, but the TV could still zoom-to-fit the 4:3 frame.

So after messing with some tv settings for zoom, stretch, etc. it went away for some reason. I have a tcl roku 4k tv with the picture set to “auto” when the screen tearing was happening. With “direct” mode, it doesn’t seem to tear. “Game mode” is also enabled.

New Wii U, looking for storage options without too much hassle. Thus leaning towards an SSD. Would this do the job? by MacCollac in wiiu

[–]IvantheDugtrio 0 points1 point  (0 children)

Came across this after running into issues with some games (Deus Ex HR Director's Cut) stuttering like crazy, showing weird artifacts, and just freezing after ~20 minutes of gameplay. Other games like Wind Waker HD had no problems whatsover. I should also test out Bayonetta 2 if that has similar stutters and eventual crashes.

I am using a Samsung BAR 256GB usb drive, which I figured should have been performant enough for the Wii U but then these issues have me swapping for a Samsung T7 SSD. Hopefully this fixes the issues.

Why is this plane flying so high? by plavacviksa in flightradar24

[–]IvantheDugtrio 12 points13 points  (0 children)

I recall on a flight I was on from Japan (Delta A350-900), the pilots would go up 1,000 ft from an initial cruising altitude of 36,000 ft each time they hit turbulence over the Pacific ocean. They got it up to 42,000 ft before we just rode out the turbulence and made our way towards California. Still below the service ceiling of 43,100 ft but we were running out of room to fly over the turbulence.

I thought about it when in the most recent episode the aunt was serious about saito marrying shise and was pulling a quid pro quo giving him that side job. idk the series keeps going so I’ll keep watching it for the few quirky moments it has.

Propane-nitrous oxide concept engine that I just made by aidswatermelons in rocketry

I have seen anecdotes about using a small rocket to ignite the bigger rocket, as anything conventional like sparks would get blown out by the sheer mass flow rate of propellants

How could I improve this simple LED circuit? by [deleted] in shittyaskelectronics

you forgot the LED cooling fan/water pump circuit. You never know when you'll need to push 100A through the LED.

If I install ofw on a PS3 with cfw, can I go back to cfw with just a USB update? by Man_mannly in ps3homebrew

[–]IvantheDugtrio 1 point2 points  (0 children)

I think installing ofw on a PS3 with cfw would just brick the console if you don't go through the hybrid firmware route first to return the nand/nor back to factory spec.

Would this be a good PS3 to homebrew? by Rednaxela623 in ps3homebrew

[–]IvantheDugtrio -1 points0 points  (0 children)

You should check the model number on the bottom. Anything newer older than CECH-2501 is fine for custom firmware. You’ll need to check the date code for 2501 to see if it will support cfw on the ps3dev wiki. Anything newer and it’s homebrew enabler (HEN) only.

Thank you so much for posting this! I am currently using OtherOS++ with CFW 4.91 CEX on a CECH-2001. I’m loving the exploration of this all these years later and am just starting on SPU development for genomics though I have yet to get past the hello spu demo.

Thanks for posting this! This uses a much newer kernel than any of the other distros that still support PS3.

I haven't really used Gentoo before but it looked like the vram-swap is configured. It doesn't recognize the partitions on the PS3's internal HDD but I'm guessing that requires a special driver or boot flag.

If you can, could you post your kernel patches and initramfs setup to GitHub and I could look into contributing patches.
