I'm running 546.01 on an RTX 4090 but the issue really seems to be one of how the game is running so maybe CPU-related? Are you using an Intel CPU? I've seen cases where AMD vs Intel can make a difference. Donald Duck Quack Attack (aka Goin Quackers) has a fix for animation timings but I don't know how to debug stuff like that.
