I'm playing Elite Dangerous.
I added the reg key and tried using Ctrl+Numpad1. No difference. I made sure Numlock is on.
I downloaded "Oculus SDK for Windows" and opened the tool, but it says ASW (4th line) is already disabled. Hitting Ctrl+Numpad4 or something like that doesn't change that value, and it's stuck at disabled.
But it's not disabled; as Elite Dangerous is running at 45FPS which seems to indicate ASW.
