Favour Resolution. Downsampling is amazing. Foliage would benefit the most from that.

That's what I don't understand.  does SSAA mean more things pop up in game and appear on screen? How exactly does it work.

Going off DF's analysis and my own experience from a few hours play, there's almost no reason to go for the performance mode. It maintains a solid 30fps lock 99%+ of the time in resolution mode, and that remaining 1%~ is minor. Even if you're someone who values performance, it doesn't seem worth the drop from 1800pC to 1080p.

But what graphical performances does it enhance.  I don't remember ever hearing. 

All it does is reduce the native render to 1080p to ensure it hits the 30fps target. To the best of my knowledge, that's all it does. Given how well it already hits that its 30fps target in 1800pC mode, it's a bit pointless.
