That's a big pile of mashed tatties.
I got RDR2 sort of cheap, which is basically GTA on horseback so been playing a lot more of that than I thought I would.
Biggest problem was the persistent sound issues (the sound would continually cut out until you double tapped ESC to break out of game and back in), but finally got it sussed..
Because I have a 4K monitor, any res below 4K isn't actually running true fullscreen, it's Windowed Borderless, which gives background apps the opportunity to interrupt. Once I'd set the res to 4K and dropped a lot of settings to get it running smoothly, the problem disappeared.
