We have been experiencing stuttering especially on side-to-side head rotations, both on 4.17/4.18 but also on old packaged experiences on 4.15/4/16. Turning AWS off seems to make it better, even if it is not completely solved.
We have been using the Oculus Tray Tool, a free utility which can set ASW (and some other parameters as well) on startup. You can find it here: https://www.reddit.com/r/oculus/comm…lus_tray_tool/
