Hi to all, I'm running Parallels 10 on a 5K iMac with yosemite and 8 gb ram. When I try to run the game "War Thunder" I'm getting a windows message (while the game loads" saying that due to graphics card restrictions the game's video defaults have been reset. The upshot is, I am unable to play, the screen goes just about completely dark when you are in the games "Hangar" area. I was hoping that someone here has seen this and knows a work around. Thanks!!
