-----------------------------SOLVED--------------------------------- Hello everybody, I have been trying to play DayZ for three weeks, but I have one big problem - so many lags. First of all, here are my specs: My notebook's specs are: Intel Core i7-620M (2 cores) 8 GB RAM nVidia NVS 3100M (512 MB) - latest drivers installed game is installed on SSD (Samsung 830) Win 7 (64-bit) in-game settings: 1024x768 Graphics memory: default everything else is set on the lowest or disabled windows settings: I have changed config files: shadingQuality=0; shadowQuality=0; mouseSmoothing=1; viewDistance=800.37439 GPU_MaxFramesAhead=1; GPU_DetectedFramesAhead=1; I have Arma2 Free and Arma2 OA. I have installed latest updates and versions, but I have problems from the beginning - across different updates and versions. The problem itself is this:When I start playing, everything is ridiculously fast, but after like 5 minutes it starts lagging (FPS drop down to like 3). It starts slowly, but after a while the game itself is unplayable. The fix is to Alt+Tab to windows, wait for 30 seconds and then Alt+Tab back to game. After that, everything is fast for a while. For me it seems, like the memory is full and by doing Alt+Tab I release it and I can play again (for a short period). My tests: It is propably not the graphics problem - tried different settings and my friend have integrated graphics (Intel HD) and he is playing on medium settings. It is not server problem - tried different servers, different versions (Lingor, Panthera) It is not RAM modules itself (switched them - had another 4GB) Tried -winxp launch parameter - doesn't help at all Please give me suggestions for solution, because it is really frustrating to Alt+Tab every 5 minutes. Thank you Karlos
