[SOLVED] Ambient Shadow filter drops my fps a lot

[JESTERRRRRR]

You could try this SSAO

[WIP] BasicSSAO – Added optional smoothing

I finally decided on a method for smoothing out the rough edges that has the least impact on performance and gives good results. I decided to go with shader generated noise, so no noise texture to sample from. It has 2 modes… UseSmoothing & SmoothMore. The second smoothing pass is optional via SmoothMore, but double the texture lookups from 4 - 8. Even just using the basic 1 pass, the results are awesome… the second only slightly improves the smoothing… so not sure if it is worth the perform…

Had almost no effect on my FPS, not quite as nice looking, but decent
