Two days ago Nvidia released their new Geforce 260 beta drivers for public testing. After installing them myself this morning and checking in the control panel's multi-GPU settings, I found that the default CoH multi-GPU rendering setting had been changed from "Single GPU" to "Force Alternate Frame Rendering 2". I immediately fired up CoH to check this out, and sure enough, it works like a charm! I monitored my GPu activity with EVGA Precision (I knew that the bug with RivaTuner monitoring programs would lock up the game when I tried to make any adjustments, but I needed it for testing purposes), and both GPUs were definitely working. I cranked the basic ultra mode slider up to max, 16x AA and managed a very respectable 30-35 FPS average in the open world in busy zones (Talos, Atlas Park), and 45-55 FPS while indoors on my two GTX 460s at my native resolution of 1920x1200; people running with 470s or 480s in SLI will definitely see much greater improvements than that.
Now technically speaking, this is not true SLI, so there can be a limitation on performance versus the improvements from actual SLI, but since any sort of multi-GPU support has been missing for the last few years I'll take what I can get.
These improvements were not in the beta patch notes. These are beta drivers, and there most definitely are some bugs still, so if you're not willing to possibly run into some issues with new drivers, I'd suggest waiting for the WHQL versions to be released. As this release is an extensive overhaul to Nvidia's drivers, it will probably be a few weeks and another revision or two before the WHQL versions are released.
To my knowledge, ATI /AMD has not yet brought CrossfireX support back to CoH (at least it is not in their release notes for 10.8), which is surprising given that CoH: GR is all over their driver download page. I'd expect that ATI/AMD will release a Crossfire profile for CoH very shortly as there is obviously heavy cross promotion going on between ATI and CoH right now and they probably don't want to be lacking a feature like this when their competitor has it.
