Vortix

Hey guys i really need some help i would be so thankful if anybody could help me. I got Arma2 via Steam just to play DayZ just two days ago. Just as i started the game i got insane fps problem (i know many people are complaining about the same problem here) so i started reading forum posts and found the tip where it says you should go in the Arma2 and Arma2OA cfg folder and replace numbers here simply to a "1" (btw sorry for my possible bad english, im also not that familiar with technical stuff all around the computer at all).GPU_MaxFramesAhead=1; GPU_DetectedFramesAhead=1; Well, so far so good, i did this but it didnt help at all, nothing changed. I checked like all possible driver updates and stuff, in adition to trying to keep the game running with all possible graphic settings ingame. I know my computer isnt the best (Core 2 duo / Geforce gtx 260 / 4GB Ram) but please dont tell me like "go get a better computer and stuff", because my brother can run the game easily with the exact same computer (which confuses me even more). Im pretty sure reinstalling steam and the whole game again wont help at all so.. If anybody got another idea which could be helpful please tell me. EDIT: Its not continuously lags, its like the game freezes all 5-10secs for about 2-5secs.. actually i got a pretty good frame rate if its not "frozen". Oh yea after reading EpicA Trains post below, i noticed that my sound also lags during these "freezes" *lol...
