Im still having this issue on a new comp (not going to list the specs, but it is overqualified for tor on low settings). however, i have a friend on a 3 year old macbook (Not a pro) running xp who was also having this problem. but the other day for him the issue just suddenly disappeared. he now runs 20+fps in warzones, while i am still geting 5 fps on a much better computer. sigh. whats up with that
