Did I just become the first person in the world to complete a Beat Saber level with my Oculus CV1 under Linux? I think so! https://t.co/uOCc67gqId @OpenHMD

[Jan Schmidt @thaytan]

@Zimtok5 Ah! They've added the Microsoft EDID extension that marks it as a VR display to Windows. That's pretty clear evidence to me that Sony are about to release a direct PC adapter, and not a streaming solution!

[Jan Schmidt @thaytan]

@Zimtok5 I'm having the opposite experience on Linux. Suddenly I can use it as both a cinematic monitor in 1080p and a VR headset at 4k120 without needing a custom kernel and EDID override. The 4k90 mode works now too! I wonder what Windows doesn't like for you.

I'm not posting here on Twitter any more. If you're interested in Linux VR stuff, you can find me on Mastodon. @[email protected]

@uniVRcity_fr @staccado @iVRy_VR @mukbun1 Totally! That's pretty much what my screenshot is - just playing a video of HL:A into the headset, in stereo for both eyes. I could have used a 3D movie.

[Jan Schmidt @thaytan]

@uniVRcity_fr @staccado @iVRy_VR @mukbun1 Just to be clear, this was me playing a *video* of HL:A into the PSVR2, not the actual game.

[Jan Schmidt @thaytan]

@BattleAxeVR @csolisr @notnotzecoxao @karolgasinski @MonadoXR If it's just an "DSC on/off" toggle, that wouldn't get you there, since the headset reports that it does not support DSC. If it lets you actively force the DSC compression parameters regardless that could work and I'm sure @iVRy_VR would like to know.

[Jan Schmidt @thaytan]

Woo! I just became the first person in the world to play a (screen recording of) Half-Life: Alyx on a PSVR2 in Linux, after hacking my kernel to get 4000x2040@120Hz output working

[Jan Schmidt @thaytan]

@boberfly There's a few steps to it right now. If you have an AMD 6x00 series GPU with USB-C port and want to try, jump on the @monadoXR discord (link @ the bottom of https://t.co/FD1Zm6IjoE)

[Jan Schmidt @thaytan]

@NathieVR Satisfying! But still a lot to go to get a real driver - this was just (finally!) lighting up the screen and playing videos.

[Jan Schmidt @thaytan]

@HaareBlond @iVRy_VR Yep! That's a screen capture of what was drawn to the PSVR2. I'll try and get some through-the-lens photo

[Jan Schmidt @thaytan]

@Love_Hart942 @iVRy_VR I couldn't have done this if I wasn't working with @iVRy_VR ! All the protocol investigation they've done enabled it! I just got lucky to be in the right place to hit the right key after months of collectively trying things that haven't worked. Huge credit goes to @iVRy_VR !

[Jan Schmidt @thaytan]

@beregudaio A long way from any of that - this is only just managing to light up the screen at the full resolution. Not even 3dof IMU tracking there yet.

[Jan Schmidt @thaytan]

@karolgasinski There's been an ongoing collaborative effort on the @MonadoXR discord, that's been stalled on getting the VR output mode working. Turns out it needs DSC, but the headset's DPCD doesn't advertise it. Instead, they hard-coded the params into the PS5 GPU driver.

[Jan Schmidt @thaytan]

@johndmcmaster @gstreamer You should read https://t.co/tIGBLAcyFE before thinking of libuvc as a nice tidy cross-platform option. In general, I think I'd be aiming to extend one of the native API plugins with the controls you need like WinKS or MediaFoundation on Windows

[Jan Schmidt @thaytan]

@halfline I have heard someone say 100deg for Vision, and resolution appears to be best in class at 4k per eye

[Jan Schmidt @thaytan]

@natalietran It's clearly a prop clue for the next Da Vinci Code movie

[Jan Schmidt @thaytan]

With that, and the protocol data I gathered a few weeks ago, I think I'm finally ready to attempt WMR constellation tracking

[Jan Schmidt @thaytan]

https://t.co/V0SbHjtHrG merged to @MonadoXR - one step closer to complete WMR controller support for all headsets

[Jan Schmidt @thaytan]

Another step: https://t.co/aoxq1ySjKv adds support HP Reverb G2 controllers connected through the headset (as they ship from the factory).

@jdub I am not yet convinced that human intelligence is not just (more complex) trained pattern matching and response tho
