Hello, I have a late 2012 MAC desktop, I currently have Parallels 10 installed and of course the latest OS for MAC, my guest OS runs Windows 7. I had recently Dowloaded a game on STEAM called S.T.A.L.K.E.R. Call of Pripyat, after the download at first the game was running fine, i was just messing with the games settings to find a good balance between graphics and performance. I tried to start the game just recently and it caused my Guest OS (Windows 7) to crash, so I'm right back at my parallels desktop control center, then i have to restart my guest OS again. If any one out there can help me with this problem that would be great, i have tried to tailor parallels configuration to support gaming, but i still get the same results, i have other games i use on my guest OS just fine, no problems. STALKER was working fine to but just died on me all of a sudden, any help would be appreciated.
