I ran into the same issue investigating this this morning. I wondered why it showed low fps, but the actual rendering was not choppy or anything like you'd expect whne framrate dips below refreshrate(I'm using a Dell FP3007-HC).

I tried FRAPS, saw a minimal improvement in performance...1FPS only, actually, with the hotfix.

Anyway, I started playing to see if some of the rendering issues I had seen with 7.10 were gone...got kinda lost in the game...then had to step out...so I apologize for the late response.

If you guys would like more screens, LMK, and I'll toss some up. I just got home again, so I'll try to capture some comparos...
