Is Ambient Occlusion a thing in GTR2?

[Shovas]

I had to re-do my nvidia profiles after a clean reinstall of the drivers wiped them all so I checked them all one-by-one this time and I couldn't tell if Ambient Occlusion was doing anything. Based on A/B screenshots I've seen online I like the effect but I'm not sure I'm seeing it in game.

Is it even a thing that applies to GTR2?

A while back I switched it on and if I remember rightly I had a small performance hit but to my eyes no visual AO benefit. Haven't got the best of sight though...

Don't think so, it seems most post processing solutions that I know of can't access screen depth buffer

Thanks, guys, I figured it might not even be supported/supportable

I did read one tantalizing thing where DX9 and previous games can do it if you disable antialiasing. Not that I would want to lose AA but I might try it and see what happens.
