- Unofficial AMD Radeon -Drivers reveal FSR 4 DLL file
- The file suggests that RDNA 4 GPUs have access to FP8 WMMA which may be a prerequisite for FSR 4
- Games that already have FSR 3.1 will have FSR 4 implemented immediately
While AMD has already confirmed that the new FSR 4 (Fidelidefx Super Resolution) upscaling method will be exclusive for RDNA 4 GPUs, some players held hope that older GPUs could one day benefit from its addition – but a recent revelation may have shut down that option all the way down.
As reported by Videocardz, an FSR 4 dll file was discovered in unofficial Radeon drivers.
According to Osvaldo Pinali Doederlein on X, FSR 4 uses a machine learning algorithm with an 8-point liquid point implementation and reports also suggests that RDNA 4 GPUs will use FP8 WMMA (Wave Matrix multiplies accumulated that helps to speed AI applications), Which is what is allegedly required for FSR 4 to function.
When receiving no FP8 support at all.
Since rival Nvidia’s DLSS 4 scale scaling technology will be available to all RTX GPU users, this can easily lose Team Red Red some fans.
What does this mean for RDNA 3.5 handheld games -PCs?
It’s back to see if RDNA 3 GPUs will be able to cut into AMD’s new FSR 4, so I fear what this could mean for handheld games -PCs. Upcoming devices like Lenovo Legion Go 2 use Ryzen Z2 Extreme APUs, which are probably built-in RDNA 3.5 architecture.
If that wasn’t already clear enough, scaling will be an important feature for games in the future, especially graphically intensive. If new handhelds cannot benefit from what Team Red’s new framework generation has to offer with regard to performance improvements, these handheld capabilities will be able to play the latest AAA games will be compromised.
Games that already have FSR 3.1 support will instantly have FSR 4 implemented when it becomes available – so it raises the question of whether this could mean that older GPUs could still use FSR 4 Super solution, but lose on potential improved Framework generation technology, similar to Nvidia’s DLSS 3 and 4 with RTX 3000 and 2000 series GPUs. Hopefully older AMD GPUs can get something out of this …
