Erratic and increasing loss of tracking (white out) in VR (Solved)

[VR_Dogfighter]

Recently I'm suffering what appears to loss of tracking when playing with the Vive, which starts out as the odd flash of white/grey screen but during a game will increase in frequency until its unplayable.

I can probably play for about 30 minutes without a problem, but once the problem starts it takes about 15 minutes to escalate to unplayable. Restarting the PC fixes it for a while and I don't see this with other VR games.. 

 

Any ideas .. Cheers

Graphics settings too high..reduced MSAA to 0 and not blanking out now..

 

Not sure why it would run with decent FPS with MSAA at 2 then develop problem, but fingers crossed!?
