Fair point, I’m not really sure on the exact power profiles the Frame supports tbh. I’ll take a look a bit later.
I have exceeded 20W during standalone play, and right now my game of choice is the vr mod for half life 2, which works fine in standalone.
Even with a 20W supply and 5W from the onboard battery you will extend the lifetime by a lot.


It almost feels like the game is native vr. The only awkward thing is that you need to use a controller button for opening doors and such.
Whether you should play depends on your vr legs. Alyx is definitely a more beginner friendly experience, while half life 2 vr is way more fast paced.
