I just finished a test with Forza Horizon 5 with RSR enabled 2K and the normal 2K my screen is 4K but my card is not strong enough to play 4K maybe the old games and to be frank I didn't notice anything different and in addition when I activate the RSR I lose FPS when I put it in 2k and when I put it normal in native 2k I have more fps so I'll tell you the truth I find that it's not much use thing my card is an RX 5600 XT and my processor is an i7 6700 since it came out I tested someone games and I find that the FPS does not change anything weird?? Frankly it gives me what to play with RSR activate in 2k if it's the same image in native 2k lol and in addition I have less fps there is surely something I am not doing correctly
