My pro acted like this (greyscreen / flickering / dropped frames / poor tracking ) for the first 30 mins. I wound up resolving it through one or a combination of these items ; 1. Opt out of Steam Beta, let Steam update your SteamVR app to normal. Set the % (formerly SS) to as low as it can go. 2 . Update controllers via direct USB connection , not Bluetooth as it won't show an update is available. 3. Pair controllers to new link box 4. Completely reset system, power off and unplug power to link box. 5. Ensure Nvidia Control panel is set back to maximum performance. ( Mine switched back to maximum quality when I changed to display port) 6. Restart system. Run the room setup again. At the lowest % in steam vr , see if you can regain tracking. Then increase the % until tracking is lost , I think you have to restart steam vr each time you make a change to the %. I have a 1080ti , i56700k and first gen (founders?) Htc Vive setup , the one shipped in the giant box. Nothing on my system is overclocked.
