Hmmmm? Now I am confused!
Disabling Crossfire and using one card only does not affect performance at all. In fact, CLoD probably runs better on the one card although the usage goes much higher - sometimes 100%. Temperatures still stay below 70 degrees.
I went on the ATAG server and performance was as good if not better than two cards with Crossfire enabled.
I have tried limiting FPS to 35-40 using Bandicam which I guess is similar to your Precision software with SLI. Doesn't make a lot of noticeable difference? I get really good FPS - over 100 in certain circumstances but the stuttering still occurs with Crossfire.
I even played around with Track IR5 settings - slowing the head tracking down and increasing the smoothing option. I wondered if most of the stutters occured when looking around and the scenery was always playing "catch up". It's better but there are still stutters in level flight keeping vision straight ahead.
True that the stutters are worse close to the ground which implies that the game's complexity challenges any system.
