UE4.9.1 does not recognise Rift with 0.6.0.1, and has game breaking performance with 0.7.0.0

Can I ask if you are experiencing this slowdown on a fresh reboot?

There is a known bug in 0.7 runtime that causes severe performance issues on the second run of any VR application.

Hey ,

Is there a source for this news?

My 4.9.1 with 0.7 project runs consistently poorly; I tried diagnosing the issue by installing several different runtimes which require a computer restart each time, so this bug is not the issue.
