Hello Larian and thanks for the amazing game.
Everything was going smoothly during act 1, the game saved normally and the size of the save file was 6mb,
However as soon as I entered act 2 ( specifically after getting out of hall of echoes from lady vengeance ) I noticed huge loading time, stuttering and saving takes 3-4 minutes now, when it used to be instant.
I looked at my save file and found it's 11mb now!!
And I assume the game started to stutter and get bad latency because there's RAM leak.
I hope you fix this in the next patch because I can't play T_T
Experiencing the same problem: the game starts running smoothly and saving quickly, but about an hour afterwards, or in big fights with lots of effects being applied and surfaces changing, sometimes it takes several seconds for the input to be recognized.
Restarting the game fixes the issue (although on quitting I get an ear-raking sound stutter), but as of Arx I had to do it 4-5 times over the few hours of gameplay. Fort Joy was mostly fine as well, but in Driftwood it began to surface frequently.
