I've found that running "-malloc=system -maxMem=4094" through launch parameters stabilize the game's memory around 1.2gb, but then after 10 mins it goes into a non-stop stuttering and buildings disappears or go into lowres (or replicate on piece of texture all over it). Additionally my character goes into a low polygon affair. Game's memory usuage is down to 800mb at that point.

Couldn't verify this was constant, as I got kicked off the server, but non of the missing textures would load back as before.

Edit*Give it 10 min it will consistantly go low poly and not load textures while inducing massive stuttering and keep fps to a solid 5*

Hmm might have been lucky, but this has seemed to fix the problem for me "-malloc=system -maxMem=2047". 2047MB is the hardcoded maximum of the arma 2 engine.

Make sure that apart from those two you have no other launch options (except for maybe -skipIntro).

I took everything out and its working like before, when it had that option turned on. The new UI or whatever fixed it, or added what we had optioned.

Hello Momodane and thank you for the report.
Please make sure that you are running the game without any launch parameters. They are not supported and cause various issues within the game. As for the low polygons / lag issues, we are aware of the issue (#0017013) and it has been scheduled for a fix.
