Using Windows 10, when I brought up the GPU Profiler while in VR Preview mode, the VR windows does not accept keystrokes, ie: Esc… I believe that the keystrokes are being routed instead to the GPU Profiler window which is hidden.
I am using the Oculus Rift for preview, Windows 10, and UE4.9
Thank you for reporting this issue. I testing this on the Windows 10 machine we have here, and am seeing different results than what you are reporting. When launching the VR Preview in a blank first person template project for 4.9.2, I was able to bring up the console command and type profilegpu.
The issue I am seeing is the profile window will not appear until I exit the VR preview mode. In order to make sure our tests align with one another, would you mind providing me with some simple reproducible steps in a new fps template project and confirm you are still experiencing this issue?
