What is SSAA and Why does it drastically reduce FPS?

I saw my FPS in Metro:LL go down like crazy as soon as I enabled SSAA

I think I've always had this enabled, and had around 65+ FPS, I started messing around with the new precision x 5.2, and after that (Just a guess) my FPS was around 33, not going a single FPS higher if I lowered other settings

Super Sampling is the most intensive type of Anti Aliasing. You're basically loading every pixel on your screen several times, then shrinking the picture back down after wards. It's the most thorough way of smoothing jagged lines, but it is incredibly intensive.

its supersampling AA. basically your card will render the game at a bigger resolution and then downscale. so its exactly like playing on a bigger res monitor. for example an x4 SSAA on a 1080p monitor means your card is rendering 4K

Oh I get it now. I thought I've always had SSAA on x4, and was wondering why I had such incredible low FPS
