Here is a potential fix with a fresh install with default settings. Run this program in compatibility mode, windows XP Service Pack 3.



Simple how to:

Go to where ZombieDriverHD.exe is installed. "Steam\steamapps\common\Zombie_Driver_HD\bin\ZombieDriverHD.exe"

-Right Click on .exe and go to properties
-Compatability tab
-Run this program in compatiblity mode for: Windows XP (Service Pack 3)



This worked for me after trying older fixes which didn't seem to do anything. Let me know if this helped.
