A couple weeks ago I was playing HL2 and everything was working as expected, but now when I attempt a direct vr scan it always fails. Other games, including Black Mesa, still scan just fine. Between then and now my computer installed some windows updates and SteamVR self-updated.
After I launch HL2 and it appears in the headset I change the resolution in the settings to 2880×2160 full screen and load a saved game.
