I've got two GTX 980s in SLI and I can play the game on max settings without issues 95% of the time. Occasionally, however, sometimes when there's heavy effects (sometimes when there's not-- like when I'm activating mudras) the game will freeze for a second or two before resuming it's normally smooth gameplay.

Anyone have any ideas? I've tried different graphical settings and as I've said, it works perfectly fine most of the time.
