AMD's FSR 4 has reportedly been enabled on a Radeon RX 6800 XT GPU, which is based on the older RDNA 2 architecture.

AMD's FSR 4 Modded DLL Works With RDNA 2 GPUs Too? Reportedly Enabled On Radeon RX 6800 XT & Delivers Higher Image Quality

After the AMD FSR 4 source code leak a few days back , several users managed to enable the new tech on older and unsupported (officially) GPUs such as the Radeon RX 7000 from AMD themselves and NVIDIA's RTX 30 series. These leaked files were modded to support the INT8 version of FSR 4 instead of FP8. The 8-bit integer version was able to run on non-RX 9000 (RDNA 4) GPUs since these instructions are supported by many GPUs.

However, it looks like users are already enabling FSR 4 support on much older GPUs, such as the Radeon RX 6800 XT, which is based
