Call of Duty
We're seeing practically no difference between the 6800GT and the 6800GT-SLI in Call of Duty across all resolutions. NVIDIA includes a load balancing feature to show the GPU load on each card but it would not display on Call of Duty. We do have fairly high framerates at 1280x1024 with the 8xS / 16x AF setting so those stuck on that resolution on LCDs may be interested in this as an alternative.
Jedi Knight - Jedi Academy
Some funny numbers on Jedi Knight 2 also. Load balancing showed very little work being down by the GPU at any resolution AA/AF setting. Looks like our benchmark is very bound and the 6800-SLI setup actually takes a big hit. The fact that we're seeing strange results in both Quake 3 engine games and that this also occured during testing of the 3D1 (the 3D1 was also slower here) leads us to believe that this may be a driver problem. We'll keep an eye out on this. Again we're getting fairly good framerates at 1280x1024 with 8xS / 16x AF so that is an option for LCD users.
* Note that the custom setting is not a direct comparison between the NVIDIA and ATI card as the antialiasing setting is different - 8xS mode on the NVIDIA and 6xAA mode on the ATI.
