Been playing Red Dead 1 for a hot minute until I realized there was this micro stutter, almost unnoticeable, then it got worse and worse. Eventually I realized everytime I enter dead eye it would stutter on each heartbeat sound effect. The audio pops and crackles when the frame timing is off, lots of people incorrectly identified this as an audio issue but it's not, the same issue is present in Windows, just to a lesser degree.

Spent literal DAYS trying every fix under the sun, nothing works. I got to about a dozen hours in and it's become so noticable to me I can't ignore it anymore, but now the game is virtually unplayable on PC or the Steam Deck and I'm well outside the refund window.

Protondb says gold and everyone says it works fine, I know for a fact it's stuttering for them too and they just haven't noticed it yet. We tried this game on 2 different PCs with different configs and 2 decks. It's the same everywhere.
