Just re-purchased The Witcher 3

Just finished my second play through in time for blood and wine. Very excited to play through the new dlc on my ps4. However I also just built a rig. I7 4.0 ghz, 16 gb ram and 970 GTX. Couldn't resist the sale on steam. Pumped to play it on pc.

Pc gamers any tips for optimizing the performance?
