computer freezes with new update (1.7)

ever since the new update to V 1.0.7 my pc freezes whenever I put the headset on with vr desktop running... I maybe get one frame every 5 seconds??
Whenever I put the headset aside everything seems to run fine...

specs:
Windows 10 Pro
intel xeon x5650
gtx 1060 6gb
12gb ram

no g-force experience
deactivated msi afterburner and rivatuner, didn't change anything..

never had any issues befor, halp! ^^
