As for Red Dead Redemption 2, I honestly never thought I'd see such high frame rates in this game, but the RTX 4090 hits just shy of 180FPS at 1440p, coming in 52% faster than the RTX 3090 Ti.
At 4K, it is still pushing over 120FPS, where we are looking at a 57% frame rate boost against the RTX 3090 Ti, or 77% when compared to the RTX 3090.
