Hi! I recently discovered the STALKER games, great stuff. However, I have a problem with Clear Sky. If I enable dx10 mode, then the game crashes when I'm in the game menu after a few seconds, and when I load a savegame the game crashes after about 1 minute. This could be an xrengine.exe crash I think, as that file is "stuck" in Task Manager after I've ctrl+alt+del myself out of the game/black screen. I have a late 2012 iMac model with Windows 7/Bootcamp, 3.4ghz i7 CPU, Geforce 680mx (driver v.314.07), 16gb ram, SSD 768gb. Windows 7 is up to date. This crash happened without using any mods. I purchased the game on Steam. I would really appreciate any help. I've searched Google for a solution, but haven't found any... Thanks for reading.
