Application has been blocked from accessing graphics hardware [ERROR]
Hello guys. I wouldn't come to bother you with this issue if I haven't searched some other forums before without success. This issue is only happening with one game: Modern Warfare 3 (Steam version). Let me explain:
-First I got the "Graphic drivers stop responding...." error which is easily fixed by changing TdrDelay at the Regedit menu. I changed it from 3 to 10 and after that, the error now is "Application has been blocked from accessing graphics hardware" with the respective freezing of the game and tray notification.
I used Display Driver Uninstaller for removing all drivers from my GPU and re installing the latest version (HD 5770 AMD graphic card). Anyway, I can play ANY OTHER GAME with no issues at all. It only happens with MWF3
I really don't know what else to do (maybe reinstalling the game, but I want to be shure there is no other problem with my system). Is there any other Tdr value that can be changed?
Thanks for kind help!!!
EDIT: The only thing I can remember is that this started happening after AMD asked for a software update an a AMD Evolded app shown up asking for "optimizing games". The latest to be optimized was MWF3. I have uninstalled AMD Evolved to see if maybe it made some changes to MWF3 as a "gaming profile" style and now I can't revert that...just maybe...
