I am running on all settings high, with a 2560x1080. Everything in the game and the game itself begins to become sluggish, and soon the mouse icon is blinking when moving, and stops responding about 40% of the time. Everything slows down to a crawl, and if you continue to try to play, it begins to freeze for like a sec, speed up whenever happens in the game to the normal speed, and repeats.

This only happens from around 10-30 minutes into the game. I put all settings on lowest possible, and it started happening around 40 minutes. Not 50 minutes, and not before 40 minutes. I don't know if anyone else is having this problem, but I would appreciate any help on this issue.
