I'll throw this out there because no one seems to have mentioned it anywhere. I disassembled the nv4_disp.dll of the 177.26 drivers last week and I noticed a new string called Mosaic SLI which I can't find reference to anywhere on the web or in any other driver. This makes me speculate that nVidia may be coming out with some new SLI mode that might get rid of the current SLI issues (or the new GT200 cards already use it but they aren't telling anybody?). When I think Mosaic SLI it makes me think each frame is either broken down into tiles and the GPU alternates rendering each tile or the frame in broken down into multiple zones of elements/objects and each zone is rendered by a different GPU. Anybody have any insight on Mosaic SLI?
