Actually, there are a few launch options you can try using as well that could help (albeit marginally) ... I'm at work now and teaching tonight, so if your on TS around 11:30ish EST DM me and ill send them over... at a minimum your should run '-NoPause' (no quote) as it will help keep arma from crashing when you tab out / back in.... others i have enable hyper threading, allocates max ram/vram, cores, kills the startup vid and other bs to launch faster, etc... may only get you a few fps, but worth a shot..
