Hi mate, if you look at my spec's im getting 57 FPS (avg) with everything maxed out at 1920x1200, that said there are still some points where my FPS will drop to 6 whilst playing the game. More optimisation is clearly needed, but if you have the right kit then CLOD is almost playable other than the bugs. Regarding SLI I have seen some threads where members have claimed to have got it working with a bit of tinkering but currently there is no nvidia profile to run CLOD in SLI though Luthier claims this will be resolved soon. I hope that helps a little.
