What is "SAO"?

[Bartholomew Degryse]

I've never heard of the game's "best" ambiant occlusion method: SAO. It appears to be equal to no ambiant occlusion at all, and far worse than SSAO.

[Kaiser]

SAO is scalable ambient obscurance and is suppose to be a superior alternative to SSAO using depth mip map chains for optimization. Though personally it seems better suited as a super high quality ambient occlusion effect as its way more expensive, despite of the mip maps being used.

Everything is based off of this documentation here: https://research.nvidia.com/publication/scalable-ambient-obscurance

It has a better effect for distant geometry compared to geometry up close.

Thank you sir

If it's not working at all for you, you may be hitting the AMD bug with dFdy sign reversal; check out my pinned thread if that's the case.

Can devs add HBAO(+)/MXAO in the future? Coz all current 3 options are awful in my opinion (dark halos everywhere!)

HBAO will be considered for a future update, but I did actually attempted to implement that a while back but was discouraged when I learned that it was going to be very expensive to render.

Yeah, SAO alone is already pretty demanding in this remaster..

I have a 5 year old Nvidia card 2GB and this games runs max on 1080p with that option enabled :)

I have gtx 970 and have framedrops with SAO (along with other options, of course =) ). Still have framedrops even withou SAO, but not so heavy =)

Nvidia user here, I just personally couldn't tell the difference between SAO and no ambiant occlusion, where SSAO creates very obvious shadows at the bottom of walls.

[Phantron]

There is a difference, it's just better detailed, so you dont see the effect so strong! the SSAO shadows are all over the place, kinda
