I tested in Default X-Fire with medium settings grass and roads on ,shadows off 87fps vs off ,69fps vs on.
Default X-Fire with V-High settings grass and roads on ,shadows off 45fps vs off ,46fps vs on.
Two Worlds 2 DX10.exe X-Fire with medium settings grass and roads on,shadows off 85fps vs off ,65fps vs on.
Two Worlds 2 DX10.exe X-Fire with V-High settings grass and roads on,shadows off 52fps vs off ,55fps vs on.
Lower altitude settings produce hesitations on all tests but slightly less annoying in medium settings.The rendering looked better in the Two Worlds profile.

I started ROF with a single 5870 and when SLI/XFire was enabled got a second one .Performance went up by 50% easily so I upped the eye candy setting and got a nice balance .When I upgraded to a single 7970 the performance improved probably due to the extra memory.Adding a second card allowed me to max out all settings other than Anti-Ailiasing which is always left at 2x as thats the real frame killer.A recent AMD Driver updat introduced flicker of the clouds so I had to cut points of light from max to 15 but otherwise it runs as smooth as silk.
