So, whenever I try to run DayZ, purchased on steam, it opens, then as soon as the black screen appears, it crashes, with the error message "DayZ has stopped working." I have tried all the available fixes I could find on other threads, but none of them are working. My computers specs: -Windows 8.1 -CPU: Quad Core 4th Gen i-7 -GPU: Nvidia GeForce GT755m -8 GB Ram -Nvidia Driver and directX are both latest versions. The program works when I use the integrated intel HD graphics, but when I use those, the game is practically unplayable. Any fixes?
