Here's another round. I installed CCC 2.21 lvl 5. lvl 6 netted 16 fps. I also pulled up my old config file which I think is better than mster quality (POM on).
It's SSAO and HDR are just perfection IMO. Aside from lighting, draw distance seems to be the biggest difference between mine and the MSTR performance. I'll go through tomorrow night and mess with my own config's draw distances to see what can be sacrificed.
