I'm getting 30-40 fps with no one around in the pandaria zones and I cannot figure out why. In the middle of SW I get 50 fps with a lot of people around doing stuff, and can even get 30-40 fps in LFR during intense boss fights. Also I can run RIFT (which is far more intensive) on ultra and get 40-50 fps out in the open.
I'm not sure what's going on exactly. I realize my computer is not the best, but I think I should be getting more than 30 fps on ultra in the middle of the pandaria zones.
