Hello, I need some help, I have just bought DayZ, it doesn't allow me to play everytime i start the game it does nothing, steam shows me going into the game and then out. I had no troubles playing the Arma dayz mod. I have tried reinstalling over and over. I have also done the following with no success Update your nVidia / ATI graphics drivers. Check our Technical References page for proper and official download links. Turn off SLI / Crossfire then start the game. See if it stabilizes DayZ Standalone performance. Turn off your anti-virus software before launching the DayZ Standalone, but make sure you turn it back on after playing. Make sure Windows Defender is also disabled. Try using only one GPU first (turn the other one off via your nVidia / ATI graphics control panel) Try running the game in Windowed Mode (frequently works for low-end PCs) Disable anti-aliasing and filtering, restart DayZ Standalone Disable V-sync, restart DayZ Standalone Disable background apps, and turn off your anti-virus software In Windows 7 right-click the DayZ Standalone exe file, go to the ‘Compatibility Mode’ tab and check ‘Disable Desktop Composition’ reinstalled direct xMy specs are Windows vista 64 bit SP2 intel core 2 quad q6600 2.4 ghz 4 gigz ram gefore gtx260 Thanks for taking the time to read this. Please let me know if anyone has ideas.
