Logs probably won't help much here since it's a performance issue, but if
there's anything to see in the logs likely places would be anything generated
inside apply_fbo_state() or depth_copy() (you could try disabling depth_copy()
completely, although I doubt it'll make much of a difference). In general you'd
want to narrow things down to a specific FBO configuration that causes the
slowdown like a specific texture format or active render states.

A 6600GT should support FBOs just fine. The only other difference with my setup
that I see that could be significant is the amount of video memory.
