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.

Done.

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.

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
