Because of this "forced" SLI I get it:
Spoiler 
I'm waiting for normal support.
I have a GTX 690 and only one core is loaded .. although I installed new firewood from Nvidia ..
zadosss
I will not talk about pirates, but initially this mode did not work for me on a license. Two gtx 660s refused to work together, one at 99% loaded, the other at 11% maximum. I tried the Lord Rock method and everything worked out, the video cards work with equal load and the fps is stable at 55-60. Happy not having to wait for patches)

Thanks for the great advice. Now everything is flying!

My flight is normal, while bugs, artifacts and other oddities are not found!

Lord Rock THANKS VERY MUCH, two titans are worth and one worked, now 100 fps at max 2k
By the way, I ran into the same problem on 690 as An-Si Carto, at
first everything worked fine and then something went wrong. such a bug lies in the fact that the subsurface is transparent without restrictions.
Strange, but I have both 2980 working, and the rendering mode is set by default and the game runs smoothly without various artifacts ... The driver is new. I think they will tweak the patches for the rest, it remains only to wait for the patches.
