I just started to get this problem! Build 16176.

I get the error everytime I start the sim and I can't use GSX and many other things anymore.

Same issue here with my two 1070's. Running one card I get better performances than with SLI. Very depressing..

Good evening all, I just got myself two GTX 1070s and have been having the weirdest of issues. When I load a plane like the PMDG 747, I get the craziest spikes of FPS from about 6 fps to 40 fps. Then, when I monitor my GPU usage, it seems like it can go down to almost 3% and sometimes goes up to 45%...
