I've just made quick test of my HD5870 and I've got 20-40 fps in places that are performance bottlenecks.
Given nvidia cards are usually faster in openGL it should be in playable fps range on GTX560 but rather not constant 60fps.
Other thing is that even without distortions I still prefer this effects not exaggerated and with value 0.02 – 0.03 difference is almost not noticeable.
But that is a matter of personal preference.
My point was, without reliefmapping, offsetmapping creates distortions with high offset value.
