Test Drive Unlimited

First game and first disappointment for the HD 3870 X2 which is largely outdone not only by the 8800 Ultra (up to 26%, except in 1920x1200 + antialiasing where it's as limited as the others) but also by the 8800 GTS 512 MB in most cases. The increase in performance compared to the HD 3870 is there (it varies from 8 to 18%) and is beyond the scope of the 50 MHz increase in GPU clock. CrossFire does seem to improve performances, but only slightly. We noticed that the HD 3870 CrossFire (which in reality is based on an overclocked HD 3850 512 MB) appears to be a little faster than the HD 3870 X2.
