Its great to see it works pretty well up to 4x. Above that probably meant for video only? I think Nvidia will be asked why they should limit frame gen to their 5000 series.
Briefly drifted over/slipped that the driver is over-riding the FSR version. That's a pretty cool little detail to let slip... its the same sorta thing we have been able to do with 3rd party tools and nVidia announced at CES (DLSS Overrides). So cool to get a slip about the possibility that AMD may be doing the same.
Without the 3x zoom looks about as good as DLSS 4 to me. Id love to see a more deep dive on performance level upscaling only but I think they caught up on this feature at this point. If there is no way for Navi3 to get FSR4 then upgrading to this gen becomes more likely depending on prices...
Changes in the Last 24 Hours 2bede03 Added experimental FSR4 support for RDNA4 cards. You need to find amdxcffx64.dll and copy next to OptiScaler. Thanks to @PotatoOfDoom (cdozdil)
