Not bad. Definitely not as smooth as the Rift, but it wouldn't be noticeable to someone who only uses it occasionally. The Go controller is a little touchy, and shows up as a Vive controller for some reason. Seems to be a common issue with SteamVR.
I was monitoring bandwidth, and it stayed around 40mb/s while i was moving around. A little high, but expected.
I'll add in more textures & Revit models and see how it affects performance. I was only rendering 2 models for this one, where for a full rendering we'll have 5-6.
