Thank you for your explanations.
First of all, I already use a full blown watercooled 3D machine with gtx2080 - so VR should not be an issue.
Secondly, I plan to use VR also for my own 3D-productions. IMHO the VR resolution is the most visible drawback for my tasks. I don't like to always full zoom into, just to recognize details.
I'll wait for HTC Cosmos esp. because it does not require external mounted sensors.
