The odd thing is that I tested my framerate for other games and was getting very good framerate in games like skyrim and borderlands 2 (capped at 60 fps on highest settings).
For SC2 My GPU usage starts around 99% and seems to somehow drift down to 55% as the game progresses (not sure why). I feel as though my cpu shouldn't be bottlenecking my gpu so I'm not sure why sc2 is receiving such a poor framerate as well as annoying framerate drops.
If anyone could help that would be great.
(And yes all my drivers are current and I have repaired the SC2 game client).
