they test Quake 2 RTX, which runs really well, well enough for an official port being viable.

Portal RTX, looks like ass, but only due to the lack of a decent upsampler

Cyberpunk, runs surprisingly good when using the optimisation mod to reduce light bounces to 1. would need a decent upsampler tho as FSR3 looks apparently so bad that they don't even bother benchmarking it.

Is this cos Shu cant say PlayStallion

oh ffs... can a mod fix the title? damn touchscreen keyboards

 

[viveks86]

Surprisingly good performance on Cyberpunk. Thought it won't run at all, even at potato cam resolutions. Bodes well for next gen.

Done.

Goddamn, i thought we finally had Platypus 5

 

[Kuranghi]

Nah keep the title its very funny. I wish we could leave voice notes on our posts, you'd be getting one of me saying that out loud in various accents for sure.

 

[clarky]

Never knew there was a silent r in Plarstayshion

 

[kevboard]

the mods are comedians now are they? very funny guys!

Long live Plarstayshion

the big thing here is XeSS running on PS5, I thought PS5 doesn't have dp4a support so it's not possible to run any ML upscaler on base PS5. Said so DF themselves back then but this video says otherwise

it's running extremely poorly because RDNA1 has to emulate it fully in software.

they said in the video that they get the same performance with FSR3 at much higher internal resolutions... it's just that FSR3 is absolutely disgusting at low resolutions, so the even far lower XeSS resolution still looks better.

for example, if you use XeSS quality mode on RDNA1, your performance will actually drop below your native resolution performance. while on RDNA2 it doesn't, although it also won't give you a big performance boost either when compared to FSR3.


in short, RDNA1/Navi 10/the PS5 can run XeSS and FSR4 int8 as the shader model supports it, but they don't have any hardware acceleration for it, which will mean really bad performance.
RDNA2/Series X|S has hardware acceleration for it, although not the best, and there XeSS and FSR4 int8 will run ok-ish

the r is silent

Clicked the thread due to the title. I vote it stays

The video only says FSR3 is faster, but that is true even on PC.

And I was 100% sure it was a Draugoth thread before clicking.

they say in the video that when upsampling to 1080p, XeSS at 348p has worse performance than FSR3 at 540p
this is an internal resolution boost for FSR3 of around 2x while having increased performance. that's a really big difference. on RDNA2 the perfomance difference is far smaller, less than 20% usually.

they used XeSS at that super low resolution because FSR3 just completely shits the bed the moment your internal res dares to be lower than 1080p, due to how bad of an upsampler it is.

Pretty much anything that can do Int 8 can run XeSS.....itll just run like shit.

There can be no decent upscaler on PS5 if it has no Tensor cores or even DP4a.

Also K KeplerL2 , if PS5 didn't have DP4a how come they are running DP4a XeSS on it with decent perf?

decent performance? they had to run at half the resolution it could run when using FSR3 and still didn't reach the same performance. XeSS on Navi 10 runs emulated and has insane performance costs. it's just that XeSS still looks better than FSR3 even when the internal res is 50% lower lol

What second of the video they says that?

5700XT owners can run XeSS but it performs like crap.

 

[kevboard]

around the 17min mark. they say they run XeSS at 348p, and it runs worse than FSR3 Performance mode, which would be 540p

DF says a lot of nonsense.
There are 2 ways of running XeSS on a GPU without FP4A support.
One is through Int8 emulation on Linux through FP16. But this is quite heavy. Probably taking twice the upscaling time.
The other way is though the 3rd path that XeSS supports, SM6.4+ This is the one that looks worse and runs worse.

wonder if the performance cost is still worth it if your priority is high fidelity at 30fps.

Very unlikely it's worth it.
