Hey lads, I've just bought the game but am unable to launch it due to a GPU related issue: the game won't start when using my HD7970M gpu. For those familiar with ati products, if I assign Dayz.exe to "power saving" option in the Cataclyst Control Center the game works using my built in Intel HD 4000 gpu (with really low fps, obviously the game is not playable with this gpu). But when I assign it to "high performance" option thus forcing the game to use my ATI gpu, the game doesn't launch with the regular "Dayz has stopped working" error. Specs: 3630QM i7 CPU @ 2.4 GHz 16GB (2x8GB) DDR3 1600MHz SODIMM Kingston RAM AMD Radeon HD 7970M GPU Windows 8.1 64bit OS So long story short, how do I start the game with my real gpu without it crashing?
