Can confirm, If you use G-Sync Windowed, The latest driver breaks it completely, Go back to the previous 436.48.
For the filters you open GFE ingame, Setup what you want and then close it, You also don't need to have GFE open in the background either.
I am bamboozled, I run a game i cannot see anything as i hate tabbing i thought it had to ran at the same time. I even added them to GFE as games so you say then do not start GFE anymore just alt and f3? I need to test this more i thought iy had to be ran all the time.
There is no instructions on how to minimally use the filters what is your method?
