[Go / Gear VR] Are UE 4.20 updates relevant to mobile VR ?

@motorsep I just can say; In a project with a lot of trees, I see a 20fps increase when comparing 4.19 to 4.20. Tested the 4.20 build in another 'heavy' project without many trees or transparency and I see no increase in fps so I guessed this was the reason.

Another feature in 4.20; the splash screen is working now (1280x1440 image). project settings -> OculusVR -> SplashScreen

Edit -  after doing some more investigation:

Something is bugged...stopping & starting the same 4.20 project within 20 seconds or so on the GO,
the second time the screen stays black and you have to reboot the Go???!

If you briefly press the power button and then start the second session it works fine.

Alternating two different 4.20 projects is fine,

running the same 4.19 project many times in a row is fine as well.

Reported @ UE - hoping this gets fixed soon.
