I've done more digging regarding the stutter/freeze I'm encountering in SteamVR.

It happens every 5 minutes, on the dot, at the same time as a steam webconsole message "loaded action manifest for". It's not game-specific, it happens even in SteamVR Home. I've also removed OpenVR Advanced Settings, the only OVR plugin I have running.


Last time someone suggested I reinstall Windows, but I'd really like that to be a last resort. Anybody have any ideas now that I've got more specific details?
