FSR4 on RDNA2 and 3 comparison

This is the Integrer version of the FSR4 code. Its not official yet, so it requires a dll swap to work on RDNA2 and 3.

Runs pretty damn well on RDNA3 cards. RDNA2 takes a substantial hit comparatively though so not sure it's worth using on that over 3.1, would have to see the quality difference in person to judge. Hopefully it gets supported officially at some point so you don't have to bother with the DLL swapping.

The performance mode on FSR4 still looks way better than FSR3.1 quality. And they have similar performance.
So even on RDNA2, its best to use FSR4.
 
I'm on Nvidia, but I still would have liked to see 1080p covered by Tim with this. FS3 Performance @1080p is unusable, but I bet it's actually passable with this INT8 model... and probably still better than FS3 Quality at that res.
 
At this point they should probably just enable the support across the older cards, and recommend to just knock it down from quality to balance...since FSR4 on balanced likely looks better than 3 on quality anyway.

The 9070XT is still good value in the market.
 
Works great on Steam Deck as well, at lower resolutions. Unlike FSR 3, which looks pretty terrible in most games at such low res.

AMD really should push this out publicly.

It's the same DLSS 3/4 situation where you go up a version number and at the same time go down from quality/balanced to balanced/performance to get back your frames from the increased performance hit but at the same time get a better picture than on the upper quality setting from the previous version.

From my personal experience is not that impressive in handheld mode on Switch 2. At least not in Hitman 3.

It would be pretty hard for you to be impressed by DLSS if Google AI is correct in sourcing that Hitman 3 handheld mode does not use DLSS at all.

Well DLSS > FSR, so if this is worse than FSR, then it goes to reason it's not using DLSS properly or at all.

Paradoxically FSR artifacts are less visible in a portable screen and I haven't noticed great difference between RDR1 and Hitman outside a better AA for the latter and more aliasing in the Rockstar ip.

Decky framegen plugin, Is this the same plugin that gives insanely bad latency for sake of FPS Number go up by any chance?

Nothing on the Switch 2 is using DLSS from what I've heard, DK is using FSR for some reason.

I believe Cyberpunk uses DLSS.

I also looked up online and nothing says Hitman uses DLSS on the Switch 2, so not sure what that Karim guy is talking about.

This happened because AMD is working on it. Too slowly, apparently lol.

AMD's human resources for AI are spread out across different AI instruction sets i.e. XDNA AI, GCN 5.x with Tensor cores (CDNA), RDNA2 RPM shaders, RDNA3/4 WMMA (feature differences) and CPU AVX-512-VNNI.

NVIDIA focus on CUDA's Tensor cores with minor feature differences. NVIDIA has superior CUDA ecosystem.

All RTX architecture's command processors are custom RISC-V.

AMD's AI silicon effort is a mess.

Incoming MI400 is based on RDNA 4.5 (GFX 1250) replacing GCN5 based MI350 series. When MI400 is released, server GPU would be common with consumer RDNA 4.0 GPUs. This leads into UDNA (aka RDNA5).

Not if you just swap dll's.

Frame generation isn't great at lower base framerates in general. And with Steam Deck's hardware is a little long in the tooth at this point, its not really worth turning on most of the time.

And? I mean this gpu use also infinite cache and xsx not, seems nothing but I don't know if FSR4 can be more expensive in ms usage for the XSX gpu.

They are both RDNA2 GPUs. The Series X doesn't have L3 cache, but it has 560GB/s bandwidth. The 6750XT only has 430GB/s

Infinite cache is a lot better to have than the series X bandwith... we have to see what kind of quality could offer with XSX and at what ms cost. I have my doubt couldn't be that cheaper or optimal to use looking how work VRS but again is just my thought.

What are you even talking about?

I suspect it could cost more gpu mss on xsx and couldn't be even worth it considering the very low resolution where should be used. FSR4 is still AI based guess more TOPs helps to have faster calculations and XSS us scarse on it.
