Performance Optimizations

Includes quality and performance optimizations for the following titles:

• • Star Wars?: Battlefront
  • Fallout 4
  • Assassin's Creed? Syndicate
  • Call of Duty? : Black Ops III

This absolutely improved my fps and even stopped a lot of that load-in freezing..... until I get into the city or try to build anything, in which case it freezes up with very low frames Also I get a funny graphic bug now where at a certain time of day the ground in the distance is vibrant purple-blue. I just dose up on some jet and imagine its just a hallucination

was hoping it would fix godrays so amd users can use volumetric lighting like nvidia and console users can.
