Finally got around to playing with WindowFX and I'm very pleased with the aesthetic. However, I noticed while gaming in Overwatch and mouselooking performance is heavily hampered. Disabling WindowFX resumed normal smooth operation. Like butter. Oh, yeah!
I haven't noticed Fences making an impact.
I run Overwatch in full screen mode, set on Epic with Antistropic x8 and AA turned down a notch. I've yet to test WindowFX with other full screen games and will reply with appropriate posts as I discover them.
