Even though I play it on my old low end laptop, I still able to get a stable 60fps on medium settings at 1080p (Linux) and the game is still gorgeous looking probably looks better than most if not all UE5 games released in the past 3 years.
If you don't disable TAA RDR2 actually does look quite blurry, especially the vegetation looks terrible. I found the best results from using DLDSR as anti-aliasing, but it does take a heavier performance toll.
Also I should get around to finishing RDR2 some day.
