TL;DR AMD knew what they were doing – backported FSR4 on 7900xtx sees better image quality than FSR3 with a 20-30+% performance penalty, only provides higher frames than native at 4k. Lower resolutions lose FPS.

Its nice to have confirmation, but anyone enthusiast who understands the hardware demands of what they are doing already knew this wasnt going to work.
RDNA3 is missing hardware support and AMD simply didnt want the negative press surrounding their new launch by changing the narrative from ‘FSR4 is finally good’ to ‘RDNA3 ages like milk’, so they went for a maybe to defer the disappointment.
Losing frames/performance over native at below 4K? How’s that possible?
It weirdly is kinda a lose/lose situation for AMD despite FSR4 being a big win. With the ML aspect of FSR4, AMD has gone in a completely different direction from what was anticipated with FSR on debut.
It’s hard to believe that RDNA4 is still RDNA. It’s a massive improvement over previous generations but that came with significant hardware changes that makes the flagship software incompatible with previous generations.
Hopefully UDNA will from first to last have a fully integrated software stack with none being rendered obsolete by the immediate follow up.
FSR4 and ROCm plus all their successors working and available on every released UDNA gpu. When it’s not possible anymore like with FSR4 and RDNA3 they should consider holding it back as an exclusive tech for the successor of UDNA.
So you lose frames for higher picture quality?
Wow what a shocker
Update –
You’re a little late with this news. They’ve already made strides in mesa and proton-ge
I was able to get 10fps more than native in crysis 3 remastered by emulating -> dx11 to dx12 and then dlss to fsr 4.0.1 at 1440p in fedora
XeSS still has better image stability than FSR3.1 so AMD needs to work harder on it than jsut abandoning it in favour of FSR4. Even with FSR4, AMD thought they had caught up but Nvidia pushed the bar higher with DLSS4 Transformer model. They need to speed up improvements instead of showing nothing for months on end.
If anyone’s interested, there has been some improvements regarding fsr4 performance. Link to a [video showcase by skare1412](https://youtu.be/vE_bJ6SuzEo?si=gcN8GGmQbxEZEciG) . Enabling/Upgrading into FSR4 in Linux is also getting more automated through new modified proton versions too.
RDNA3 owners in the mud lol. The generation truly ages like milk despite having so much VRAM in all of their cards
Cool, I use the 7900xtx at 4k, ill take the extra frames please.
I use my 7900 xtx at 1440, am I just assed out then?
At 4k is EXACTLY where I would want improved framerates(and quality) from my 7900 XTX, so the fact that they haven’t bothered to do this officially at all means nothing but malicious intent from AMD, and they can honestly fuck themselves.
I never bought into their “customer oriented” act, because it always happens when things look dire for them.
At least make it an option.
it should still be worth it even if fsr4 balanced or performance is only slightly better than fsr 3.1 quality’s image quality on rx 7000 GPUs
So I shouldn’t return my 7900 xt and get a 9070 xt??
Yeah that’s understood and that’s OK. Right now the biggest benefit for FSR4 wouldn’t be performance it would be image quality and stability.
There was literally proof of it running better than native on Linux like a month ago already, it definitely can be done. Sure it won’t ever run as fast as FSR3, but it’s not true that it can only benefit at 4k
Now I’m kinda salty about having bought a 7000-series card. Though I did because the similar NVIDIA equivalent was way over my ~~budget~~ credit card limit.
