I will start with my hardware:

GTX 1070 2-Way SLI
16 gigs of RAM
Samsung 950 Pro

First, I would like to know if there is a framerate cap on the engine. I can only ever max out at 90 frames per second.

I frequently get stuttering despite my hardware as well (before you ask, I did lower the shadows). Does Deathfinitive even support SLI? I feel like my performance is better than a single 1070, but I can't confirm.

Finally, I am having this strange problem where turning the camera changes how the game is rendered. The lighting, textures, and assets change. They look like the stock effects and assets from the original port of Darksiders 2. Anybody else encounter this and know a way to fix it?
