Has anyone else had this issue? I'm running Windows 8.1 on a MacBook pro 15" retina with an Intel Iris Pro 5200 graphics chip. I've got the latest drivers installed (18.104.22.168.3960). When I try to play Call of Duty 1 with Steam, I get an error message saying that a buffer overrun was detected and the game quits. I tried uninstalling intel's drivers and just using the default windows drivers and the game works fine. What can I do about this? Are there any plans to fix this problem?
