• 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 carried out immediately

Whereas AMD has already confirmed that the brand new FSR 4 (FidelityFX Tremendous Decision) upscaling methodology can be unique to RDNA 4 GPUs, some avid gamers had been holding out hope that older GPUs might sooner or later profit from its addition – however a latest revelation might have shut that risk down fully.

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 stories 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 operate.

With this in thoughts, it might imply older GPUs will not have the ability to reap the benefits of FSR 4, as RDNA 3 GPUs (just like the RX 7900 collection) reportedly will not obtain the total optimization of FP8 WMMA, whereas older RDNA 2 GPUs will not obtain any FP8 help in any respect.

Since rival Nvidia’s DLSS 4 upscaling tech can be obtainable for all RTX GPU customers, this might simply lose Crew Purple 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 have the ability to make the minimize for AMD’s new FSR 4, so I concern for what this will imply for handheld gaming PCs. Upcoming units just like the Lenovo Legion Go 2 can be utilizing the Ryzen Z2 Excessive APUs, that are doubtless built-in RDNA 3.5 structure.

If it wasn’t clear sufficient already, upscaling can be an necessary function for video games going ahead, particularly graphically-intensive ones. If new handhelds cannot reap the benefits of what Crew Purple’s new body era must provide when it comes to efficiency enhancements, then the flexibility of those handhelds to have the ability to play the most recent AAA video games can be compromised.

Video games that have already got FSR 3.1 help will immediately have FSR 4 carried out as soon as it turns into obtainable – so it begs the query of whether or not this might imply older GPUs might nonetheless use FSR 4 super-resolution, however lose out on potential improved body era tech, just like Nvidia’s DLSS 3 and 4 with RTX 3000 and 2000 collection GPUs. Hopefully, older AMD GPUs can get one thing out of this…
