New S.T.A.L.K.E.R Shader Mod, has anyone tried it?

I have installed it but how can you tell its working correctly??

It looks the same to me, I have noticed a glitchiness now though like its having problems loading texture that was not there before and I also get occasional black banding in distant textures.

Performance may be better but hard to tell, it was fast before, so just can't tell. I am running all options maxed at 1920x1080
