AMD FSR 4 sees the introduction of a new AI ML-based upscaler replacing the shader-based one on FSR 3, which greatly improves image quality at every performance tier. The new technology, however, is exclusive to Radeon RX 9000 series GPUs powered by RDNA 4. This is because the AI ML model is designed for the newer high-throughput data formats that the AI accelerators of RDNA 4 GPUs can accelerate, which cuts out the older Radeon RX 7000 series GPUs based on RDNA 3, even the top RX 7900 XTX. The good news is that the modding community is making efforts to get FSR 4 to work on RDNA 3 GPUs. The bad news, however, is that while FSR 4 on RDNA 3 shows a marked improvement in image quality, there is a drop in performance.
Virtual-Cobbler-9930, a game modder, discovered a method to get FSR 4 to work in games such as "Cyberpunk 2077," a title which didn't even see an official implementation of FSR 3.1. For games to support FSR 4 through patches, it's generally expected of them to have FSR 3.1 support. Virtual-Cobbler-9930 found a way to inject FSR using a tool called OptiScaler, so the FSR 3.1 requirement is no longer necessary. By using a command called "WMMA_RDNA3_WORKAROUND," it is possible to activate FSR 4. It's worth noting, though, that the ML-based upscaler of FSR 4 will begin to bear down heavily on an RDNA 3 GPU, which lacks support for many of the high-throughput data sets that RDNA 4 GPUs do. This was confirmed in the "Cyberpunk 2077" test run, where performance was shown dropping from 85 FPS down to 56 FPS using the in-game benchmark tool; while offering image quality improvements. The source link below shows how Virtual-Cobbler-9930 got FSR 4 to work on "Cyberpunk 2077" in depth.
