RDR 2. Bought it back in 2019 but my PC couldn't really handle it too well (less than 45 FPS on medium), so I shelved it.
But now I have a 4090 and I'm enjoying the hell out of the game. It was slow at first but by the second chapter I was hooked. Looks damn good for a 4-year-old game, too; dare I say as good as a modern ray traced title. (I mean it's close)
