I’ve noticed that performance degradation happens when playing skirmish vs ai, comp stomps, and pvp. it becomes noticeable after starting a new match without closing and relaunching the game, and compounds after each match. after 4 matches the game is essentially unplayable without a restart.
this performance degradation happens regardless of match length, and manifests in constant freezing and lag regardless of game state. restarting a skirmish vs ai match multiple times can trigger it.
I did not notice any performance degradation from main campaign content at all from a fresh launch. I can play 10 different campaigns back to back, restart a campaign several times or load a save without any degradation. they are absolutely smooth from the 1st campaign mission and 1st hour to the tenth. the only issue with campaigns is that voices and sounds disappear like in the rest of the game.
this performance degradation existed in classic, but to a smaller degree than in de. I don’t think its a memory issue as I have plenty of ram left and utilization doesn’t show a noticeable increase. its not a gpu issue either, as graphics settings have 0 correlation with the degradation as far as I can tell. that campaign missions are completely unaffected is also strange.
I hope this helps in finally ridding the game of this serious issue.
