Well? That's a headscratcher! My squad uses TeamSpeak and no problems at all. Well except for those who need an upgraded PC. Only 2 though luckily. Do you have the same problem with an open window, other than the TS overlay? I have one squaddie that cant get in on DX11 if he has another window up. I believe it was just Internet Explorer on home page. Or email page, shoot maybe both. It seemed like it was too much for his memory. He didn't get the greatest game experience in DX9, but it would still run ok-ish. It was a lot better after we figured out the problem with DX11, and he closes windows programs while in game...with DX9. DX11 version will still lock his system up, after a while. So that's why we think it was just a memory allocation issue. TeamSpeak doesn't cause him problems, that we know of. Now that he closes other operations, its hard to tell how much TS affects his rig. Just an idea! No geek here! I am not even sure how this stuff works...but I like it!!
