Oh ok yea I already had the power saving disabled for all USB devices, i was looking for a "High performance" setting or something like that.
AND I found my problem.
Turns out SteamVR manual override was on and was setting the HMD resolution to 150% for all apps instead of going with application settings.
Turned that off, and tried again. getting 60FPS sitting on the airfield and the text in the clipboard is smooth now. didnt get to test flying because for some reason the game no longer detects my Thrustmaster TWCS throttle
It worked the other day, so no idea on that, sees the stick fine.
So far I have the Odyssey working great with AH (best I can tell) Elite Dangerous, and DCS 2.5
might be time to go ahead sell the ole rift.
EDIT: throttle is working now, game runs smooth as glass now.
