I updated my game to 0.54 through steam today. Decided to backup and remove my previous config and launch parameter so the game would start up normally.
During my first log in and play on a server, checking out the Northwestern Airfield, it took less than 12 mins before the Windows Memory Warning pops up and 2 mins later the game was forced to shut down along with steam (perhaps a crash?). Reloaded the game. Same result after 10mins of running around. I decided to modify the launch parameter to have "-maxmem=3072". Game stopped crashing, but every 10 secs or so the game would go into crazy stuttering and all static buildings/items/texture would disappear and reappear during the stuttering. If I didn't move, the stuttering would stop. I then set "-maxmem=2048" and non stop stuttering if I move 1 ft at a time.
Did notice that as long I don't move, memory stats constant.
