Wow usually runs at 30 fps, but at one point it began to consistently output about 60 fps. The size of the library (flatpak) has increased by 1.5 gb. But after restarting the computer, fps became as excessive as the size of the library. Perhaps lutris caches part of the game, is there any option why this might be. Also, wow, the processor is never loaded by more than 40% and the memory is at most 65% full.
