I know this is old but I have an issue as well. Does it make sense that I get a major frame drop just from starting TracIR just on the desktop, without even being in a game? I go from 120 to 10 PS right of the bat. Thats even with unplugging the TrackIR from USB port, I even tried unistall/reinstall. What should I be looking for? Windows 10, all drivers current.
