FSR has a wide range of applications, and any graphics card can increase the frame rate in the FSR performance mode. This makes it possible to stabilize the frame rate when using higher graphics quality settings.
Even just FSR 1.0 would be better than nothing, and work on all GPUs. Though FSR 3.1 with frame gen would be great. I was using Lossless Scaling with my previous GPU to play this game... and it worked great. Upscaling should be added imo.
