I checked my PC and it is over the recommended settings to be able to play both games and when ever I open up ArmA 2 the game will get to the menu then just say ArmA 2 has stopped working. For Operation Arrowhead it will not even open to the menu once I start it it says "No entry 'bin\config.bin/CfgInGameUI/MPTable.shadow'". Then it would load a little more and then say "Error compiling pixel shader PSSpecularAlpha:0"
No clue what I did wrong any insight would be helpful
