AMD FSR 4 Enabled On Radeon RX 6800 XT "RDNA 2" GPU, 10-20% Performance Hit But With Higher Image Quality

AMD FSR 4 Running On Radeon RX 6800 XT Gives Image Quality A Boost But At A Big Cost

Since the AMD FSR 4 INT8 DLL leak, we've known that it's possible to use FSR 4 on older GPU architectures than RDNA 4. Recently, we've actually seen successful use of FSR 4 on AMD's RDNA 2 architecture, after early efforts resulted in bugged visuals. Per a Reddit guide posted yesterday by user u/NaM_777, users of AMD RDNA 2 GPUs like the RX

FSR 4 modded to run on RDNA 2 GPUs improves image quality by "leaps and bounds," but carries 10% performance penalty — AMD's leaked source code turns into modding frenzy

FSR 4 is supposed to only work on RX 9000 series GPUs, but modders were quick to figure out how to run it on older RDNA graphics cards when AMD accidentally published the entire source code on GitHub. Several users have since tested their GPUs with tweaked DLLs, with all results pointing toward improved visuals at the cost of worse FPS.

AMD FSR 4 on RX 6000 Series: Early Tests Show 10–20% FPS Drop

AMD’s FidelityFX Super Resolution 4 has been made to run on graphics cards outside of its original design scope. Although it was intended for newer architectures like RDNA 4, users have managed to activate it on older hardware by modifying system files.

FSR 4 on Older Radeon GPUs Tested: Improves Image Quality With Minor Performance Hit

After AMD recently leaked its own FSR 4 libraries on its GPUOpen GitHub repo, replete with libraries that support older hardware, it was only a matter of time before enterprising modders started demonstrating how those libraries could be used to port FSR to older RDNA GPUs. An enterprising Reddit us...
