I'm running the game on my Mac via Parallels 10 version Version 10.0.2 (27712). For reasons I don't know, I get major graphical errors within the game to a point where I can't even play. My OS for Parallels is Windows 8.1. I've had no issues running Gmod or various other games, but for some reason I am having issues with this one. Here's a link to how the error looks: http://postimg.org/image/qbmrwqwrd/
Any suggestions on how to resolve this issue?
