I'm using an iMac 27" There are two models of the 27" but, I believe this is the PoS I own .The Mac is bootcamped, and I've been through numerous tutorials for lowering FPS lag and I've also turned all the settings down. It's helped a lot, but I'm still moving pretty slowly and looking around is a bit laggy as well. If anyone could help me bring down the lag just a bit more it'd be greatly appreciated. But, one other issue I'm having is when looking through my pack or sometimes when browsing through servers/changing graphical settings etc. The mouse will skip/glitch around. Again, any input that could help solve these problems would be greatly, greatly! appreciated. Thanks.

I know that much. But, I couldn't find it. But, I just did so thanks a bunch bro!

Yeah, I've tried that video. I've done that, still have mouse lag. I've also done most of that, I don't think I set the texture quality to high though. Thanks for the input guys. I'll give all these the run over and double check that I did everything. EDIT: Also, I've been seeing people saying that you should make sure that it's using each of the CPU's available, but, whenever I look for the CPUCount=# thing I can never find it. Exactly where is it?
