How Red Dead Redemption 2 runs on the GeForce RTX 5090
Our estimate puts the GeForce RTX 5090 at about 300+ fps on High at 1080p in Red Dead Redemption 2, which means it runs comfortably. On Low the same card manages about 300+ fps, and on Ultra about 277.
The graphics card is the limit here, so lowering the resolution or the quality preset is what raises your frame rate.
For a steady 60 fps, our estimate says: 1080p: Ultra (about 277 fps); 1440p: Ultra (about 199 fps); 4K: Ultra (about 111 fps).
