Performance profiling in VR

How can I profile properly in VR mode?

I have a game that runs at 150 FPS with ‘stereo off’ - but when I turn on stereo/HMD, it drops to around 40-45 fps.

I would like to profile to figure out why, but when I use the console commands to show the different profiling statistics, the essential left part of the profiling windows are cut off! How can I center the window on screen so I can see what’s going on?
