Just a friendly reminder to people who might be experiencing 30% drop in performance with PiTool 126.96.36.199 after a Windows 10 Update or on Windows 10 in general. There seems to be a bit of CPU consumption going towards Windows 10 Telemetry process.
A good sure fire way to deal with the performance overhead Windows 10 Telemetry zaps is to use O&O Shutup
Just using the recommended settings can make quite a difference in PiTools performance and minimizes spiking through SteamVR as a result.
Without it, I was getting spiking in SteamVR, stuttery performance in VR and near 30% drop in FPS performance. Applying recommended settings in O&O Shutup after the recent Windows 10 update with a reboot returned PiTool 188.8.131.52 back to smooth sailing.
Unfortunately needs to be applied after each large Windows 10 update.
