No stutters (or very, very few) on GPU Catalyst 10 for me. (6700k, 1080ti)
Checked out a few games; Layers of Fear, Tetris Effect, Sinners and Saints, and the Alyx Home environments. With SteamVR resolution on auto and PiTool set to 1, this is the best clarity I’ve ever gotten from the 5K+ after a year of owning it. I was even was able to increase in-game resolution in LoF and S&S with the same (or better) performance. It’s almost like having a new headset.
So far, best PiTool yet. 10/10
