Hi Nahaz. This is really an intresting topic and it helped me out alot. But still I'm having difficutlies in setting up my video settings correctly. Probably because I have quite a mixed configuration. I have a brand new GPU, but pretty old CPU, motherboard etc. Here are my specs: I've got got a Intel Core 2 Duo E8400 @ 3GHZ 4GB DDR2 Dual Channel 400Mhz RAM GPU: Asus Nvidea GTX 560 TI (Stock overclocked) Windows 7 64 bit Screen: 23" 1920x108 DirectX 11 Could you please give me some advise how to set up my settings correctly? I have Arma II, Arma II: Operation Arrowhead and the Private Military DLC via Steam. I have Dayz commander and everything patched up. I'm downloading fraps right now to check my fps but I'm sure it's really low. I've turned off my anti virus and firewall but nothing helps. I've completly copied your settings but it didn't work out neither... :( In other games like BF3 and Max Payne 3 I've experienced same kind of issues. Graphics looking really nice, but lagging like shit. Maybe I should consider playing on my laptop? There I have at least a core i5 cpu. Gpu is way less though, I believe it's the mobility radeon HD4600 series... Also I changed the parameters in the Arma2 document folder like you said to try double my fps. But i'm not sure if I did it the right way. I've edited it in notepad. So before I saw this white icons, and now the 2 files I edited have the notepad icon. Is that normal? Please help me out Update: I kinda fixed it myself, I have 60 fps now with my firewall and antivirus and fraps and everything on. I completely reinstalled all games and patches. Tips are still welcome to improve my framerate and perfomance even more.
