Summary0002691: 2-way SLI poor performance. High GPU frametimes.
DescriptionHigh GPU frametimes compared to single GPU. Double high as compared to single GPU exact! So microstuttering and overall poor performance. Nvidia drivers or Frosbite engine itself causing problem? BF4 is running without any issues so something is going on at BF1. In-game setting does not matter that they are. Frametime graph goes (SLI/CPU+GPU) all over the place but when one GPU is it smooth.

My system shound be issue expect SLI: i7 6700k/16GB RAM/GTX 780 SLI
Steps To Reproduce-Activate Nvidia SLI
-Go multiplayer or campaing
-Open console and type "perfoverlay.drawgraph 1" to see massive frametime fluctuation. GPU frametime is double high compared to without SLI.

Added new picture from BF4 multiplayer GPU frametimes just to show that there is actually more gpu use than test range where comparison pictures was taken. So higher frametimes on multiplayer also so my comparison picture is little bit false looking compared to real performance. But BF1 has that big variable frametimes that not happen in BF4.

I found one solution on my system that is disabling some feature at console using command: Worldrender.LightTileCsPathEnable 0 . Using value 0 gives better frametimes and so better fps. See photo named: BF1 LightTileCSpath.png

After 11152016 patch things are better. See picture: BF1 LightTileCSpathUpdate.png Still better performance when disabled but ok performance afterall.
