- Unofficial AMD Radeon drivers reveal FSR 4 DLL file
- The file suggests RDNA 4 GPUs can have entry to FP8 WMMA, which can be a prerequisite for FSR 4
- Video games that have already got FSR 3.1 can have FSR 4 applied immediately
Whereas AMD has already confirmed that the brand new FSR 4 (FidelityFX Tremendous Decision) upscaling technique will probably be unique to RDNA 4 GPUs, some avid gamers had been holding out hope that older GPUs may at some point profit from its addition – however a current revelation could have shut that chance down solely.
As reported by VideoCardz, an FSR 4 DLL file was noticed in unofficial Radeon drivers.
Based on Osvaldo Pinali Doederlein on X, FSR 4 makes use of a machine studying algorithm with an 8-point floating-point implementation – and experiences are additionally suggesting that RDNA 4 GPUs will use FP8 WMMA (Wave Matrix Multiply Accumulate that helps to speed up AI purposes), which is what’s supposedly required for FSR 4 to perform.
With this in thoughts, it could imply older GPUs will not be capable to make the most of FSR 4, as RDNA 3 GPUs (just like the RX 7900 sequence) reportedly will not obtain the complete optimization of FP8 WMMA, whereas older RDNA 2 GPUs will not obtain any FP8 assist in any respect.
Since rival Nvidia‘s DLSS 4 upscaling tech will probably be obtainable for all RTX GPU customers, this might simply lose Crew Pink some followers.
What does this imply for RDNA 3.5 handheld gaming PCs?
It stays to be seen whether or not RDNA 3 GPUs will be capable to make the reduce for AMD’s new FSR 4, so I worry for what this may occasionally imply for handheld gaming PCs. Upcoming gadgets just like the Lenovo Legion Go 2 will probably be utilizing the Ryzen Z2 Excessive APUs, that are possible built-in RDNA 3.5 structure.

If it wasn’t clear sufficient already, upscaling will probably be an necessary function for video games going ahead, particularly graphically-intensive ones. If new handhelds cannot make the most of what Crew Pink’s new body era must supply by way of efficiency enhancements, then the power of those handhelds to have the ability to play the newest AAA video games will probably be compromised.
Video games that have already got FSR 3.1 assist will immediately have FSR 4 applied as soon as it turns into obtainable – so it begs the query of whether or not this might imply older GPUs may nonetheless use FSR 4 super-resolution, however lose out on potential improved body era tech, much like Nvidia’s DLSS 3 and 4 with RTX 3000 and 2000 sequence GPUs. Hopefully, older AMD GPUs can get one thing out of this…
