I’m sure there are games that run flawlessly, which is why I added the qualifier “In my personal experience”. Despite trying different versions of Proton and launch options, I’ve had trouble getting a consistent quality of gameplay experience with Guild Wars 2, where after long periods of play the frames drop or the game freezes altogether. Same with competitive games like Overwatch 2. It will run fine for long periods of time, but once in a blue moon it will crash altogether. Obviously not ideal for doing fractals with a guild or grinding ranked where getting disconnected lets my teammates or friends down and negatively affects my ranking process or even catching a temporary cooldown to be able to queue up again
