During our evaluation processes AMD made some breakthroughs in Crysis with the 3870 X2 driver. We are using one of those driver builds they provided for us in our testing, which smoothed out performance compared to the driver build we had started with. A couple of days ago AMD came to us with yet another new driver build that further improves 3870 X2 performance, however that driver did not make it into our evaluation. AMD had noted Crysis improvements up to ~60% on the built-in GPU test, but going back and spot checking this in real world gameplay, we saw at best a 2 fps improvement at times. No other games we were using to evaluate were noted as having improvements, so we moved on with the previous driver as noted.
