What was the point of this post? Had nothing to do with the issue of no Ambient Occlusion.
I reported that SSAO was working on my system.
I got my gtx680 last Saturday. I re-installed Skryim. I hadn't played for 2 months.
I checked all the graphics options. I could clearly see a difference between SSAO and no SSAO.
However ....
Today I thought my Skyrim suddenly didn't look so good. Something with the shadows.
Now it seems SSAO is not working on my system anymore as well !
Very weird.
I have not changed any (graphics) settings over the last 3 days. Still using 301.10 WHQL.
Steam hasn't touch my Skyrim (still 1.5.24.0).
But somehow, my system decided to not do SSAO anymore.
