Post processing / Ambient Occlusion

[gianni001 37]

So, I love ambient occlusion but it drives me crazy how blury the game becomes with Pst processing on the minimum setting required to ambient occlusion to work (low)

 

Is there any way to have some middle ground, ambient occlusion working without having to use PPA and have a terribly blurry game?

 

Or am I doing something wrong, the game does look stunning with PPA on low and ambient occlusion on, but the blurryness just makes it impossibly to play properly
