Not entirely true... there is a lot of GPU/CPU balancing to do. You can go NUTS with it as I have but best bet is to set most things on normal then edit cfg file so that Scenecomplexity is 100000 and View distance 1600. You can go as low as 50000 and 800 but it's not recommended.
hmm having a mare with cfg settings, running like a bag of shit, will tweak
