I recently got CoD4 for my uMBP, a good game but I'd much prefer it on the Xbox 360. It seems to run fine on my computer, and it should because the specs seem fine, but Whenever I am shooting an automatic gun, it tends to slow down and shoot slower and it seems like everything just kinda slows down until I stop shooting...Does this happen to other people with the game? or is it just not running as well as it should be on my computer? Thanks!
