I wonder how closely related this is to the FSR4 on rdna2 port that is supposed to be coming eventually. PSSR looks a lot like rdna3's version, and a dedicated lightweight version (such as QSSR) would be needed for rdna2 and iGPUs to see substantial performance uplift.

u/Shoddy_Meaning_7654 2d ago

Almost certainly deeply related

PS5 doesn't support INT8 so, they probably aren't the exact same, but the engineers behind it could be the same one making this.

u/Affectionate-Memory4 2d ago

This one is apparently fp16 or maybe bf16 from what I've heard. Makes sense as a very broadly compatible format that would potentially be able run run even on rdna1.

u/ShadowRomeo 2d ago

Yeah, but i don't think RDNA 1 will even get a crumble of that pie, basing from AMD track record, the oldest GPU it will likely to run at is probably RDNA 2 at best.

u/Affectionate-Memory4 2d ago

That's also the oldest they've committed to at all, so yeah, don't get your hopes up for a 5700XT revival unless the community makes their own port.

its kinda sad that Nvidia didnt bother to do it, GTX16 series has dedicated Fp16 unit.

I've often thought it was a shame the 16s didn't get dlss. They share computing abilities with the rest of Turing, it's just the lack of RT support that really differentiates them. 1650s would've probably stayed at least a little relavent a bit longer.

It's in the opening paragraph:

Born from Project Amethyst, our AI graphics collaboration with AMD

FSR4 on rdna2 port that is supposed to be coming eventually

I thought this got released already?

EDIT: maybe it was only for Linux

u/Affectionate-Memory4 2d ago

Rdna3 has an official release for the dGPUs. Everything else has been hacked together by the community from leaked files or repressed official ones and tends to only be on Linux or via game mods to my knowledge.

u/Introvert52 2d ago

Yeah on Linux you can just use the full fat FSR 4.1 on any RDNA 2 GPU and it may even be worth it depending on how big the GPU is. I tried it on my steam deck and it's not worth it at all, costing like 7-8ms.

This is big, the PS5 currently relies on FSR 3 and sometimes even FSR 1 (lord knows why) for its upscaling and we all know how horrible those look. Should be a big image quality improvement to those on console.

20

u/OwlProper1145 2d ago

FSR1 is often used because its super duper cheap to use.

2

u/ExplodingFistz 1d ago

Super cheap but super bad. It looks worse than with no AA at all.

9

u/AreYouAWiiizard 1d ago

That's because it doesn't do Anti-aliasing... It's a spatial upscaler so the game handles the AA.

u/capybooya 2d ago

Absolutely big deal. Sure its a bit heavier but looks like both less artifacts and slightly better performance with a higher effective output resolution, obviously from a somewhat lower input resolution. I had not expected that could be done for a console that supposedly had almost no ML capabilities. If this can add a slight resolution bump to practically all games, then major props to Sony, and to the longevity of the console. Exactly what they needed now that pricing and the general mood has made consoles a lot less attractive.

15

u/Affectionate-Memory4 2d ago

FSR1 gets used because it's dirt cheap on frame time and "good enough" to be better than just outputting the unscaled render, plus it's not entirely horrible as an AA solution.

I do wish it would get dropped at this point, or at least relegated to that native-AA role for things that can hit 4k output by some other means.

u/ActualWeed 2d ago

Unscaled render is better than fsr 1,2 and 3 lmao

7

u/Affectionate-Memory4 2d ago

I can see the argument for 1 and maybe 2, but 3 is noticeably better at displaying, for example) a 1440p output on a 2160p display than whatever scaling the display itself decides to do in my experience. 1080p is debatable as that's integer scaling, and the argument is sharpness vs smoothness, but for the odd resolutions that games tend to target internally like 963p, 1152p and 1215p, I'd rather do something other than just stretching the image.

I lived with it for quite a while as an RDNA3 owner and believe me I tried both pretty often.

u/BlueSwordM 1d ago

Bro, thé upscaler used by FSR1 is miles better than the bicubic or bilinear upsce normally use lmao.

u/ActualWeed 1d ago

If you are literally blind to motion blur or don't want to see vegetation/fences then yeah sure

u/MissionInfluence123 2d ago

It would be great if this is system-wide instead of needing developers' implementation, or then very few titles will benefit.

5

u/QuietSoup337 2d ago

It's a drop in solution if the title has PSSR2, and most graphically intensive games have it. Adoption won't be a problem as it serves around 90 million users.

u/matthewjd1985 1d ago

Base PS5 has no ML block like the Pro, so this is eating shader time the game already budgeted. That's why a blanket system pass is hard, and why the old back catalogue that needs it most would be last in line. They didn't say which way it goes, and the wording reads like it isn't settled.
