Hi there. I've been using PlayOnMac for the past few weeks and while it runs most games flawlessly through Steam (Dead Space, Morrowind, Half-Life, etc.), I'm just starting to get comfortable with the Steam Refund service thanks to a few games either running poorly or outright not running at all. Unfortunately, I'm currently having the former issue with Deus Ex GOTY Edition on Mac, and this time, I don't really want to give up, because I really, really want to play this game without issues. For some reason, anytime there's something moving on screen (including moving the mouse) that thing is covered in a strange jumble of colors, which kills the immersion for me. I'm just guessing this is a common issue, but I don't know what to do about it. Also, for some reason, screenshots don't capture the effect.
As for my system, they're just the default specs for the new 2017 13-inch Macbook Pro.
