according to this slide from Oculus Connect 3 it should be possible to enable Asynchronous Space Warp (ASW) on Runtime 1.8, using a registry key:
I created a new DWORD-32 value ("1") as there was no further info about that. I had to create the whole structure as there wasn't any "Oculus VR, LLC" key under HKLM (only under HKCU).
Then I restarted the Oculus Software from the "Beta"-Tab in the settings. When running any VR app and pressing Numpad1-4 there is still absolutely no effect.
I also tried to create a new key (= folder) with name "AswEnabled" giving it the default value of "1". Nothing.
What did I do wrong?
