Yeah that makes sense, I think what I'm experiencing with Link are the v12 stuttering issues others have been experiencing, apparently this is affecting Rift and Rift S headsets as well since that update, at least Oculus has acknowledged it and is working on a fix:
It isn't every game I get stutter in, though Pavlov and especially Asgard seem to have issues. I get
massive stutter in Asgard's Wrath using Link especially in the tavern, and that isn't present over VD (can't seem to launch it with ALVR).
I really was surprised just how much smoother ALVR feels, the recent experimental versions use sliced encoding like VD, it definitely feels more responsive than VD so you may want to give it a try if you're interested.
As for the Link either my issues are the v12 stuttering or maybe it's an issue with my usb 3.0 port, though Lone Echo is buttery smooth over Link so I don't really know what to think. Hopefully Oculus releases a fix soon so I can narrow down what the culprit is.
