12 months of trying to resolve SLI - time to turn to square enix

[Schmak01]

The game still has issues such as very very poor performance when advanced lighting effects are on screen (such as the startup screen or dungeon portals) I get ~80fps at the startup screen with SLI off and 18 with it on :P (this is WITH it working post fix) Other than that, Im now able to get 120fps+ on maximum at 4680x2560 now. Its wonderful. Sad that it took this much time and effort. Also extremely pessimistic regarding the lighting issue being addressed considering the fact I had to fix the SLI issue on my own BUT... its progress.

This is the EXACT same issue I am having with 2 GTX 970's, I had zero issues with my old 680's in SLI. I posted some screenshots on another thread. at 1440p I get 150-120 fps then as soon as the shimmering effects are in my field of view it drops to 30-40. It gives it a slowdown motion, as someone else described, like the matrix. I noticed that the slowdown of my character animations matches the timing of the lighting effect. If stood next to it with my nexus out, the smoke effect will mirror the pulsing pattern of the light effect. Rotate around and the lighting effect of my nexus and fps is normal.

Thought I would add my pictures - THIS ONLY HAPPENS WITH SLI On. Turning it off eliminates the problem, but I am not using my second card and average 70ish FPS on 1440p highest possible settings. Vsync makes no difference.
Image portal in view - low FPS
