Compatibility Report

The latest versions stopped Whirligig from being usable for me, I had to revert to 4.7462. It looks like you're not having my issue though? (Vive controllers not appearing, UI went down out of reach of the mouse cursor)

EDIT: This is with a Radeon RX 580 (Mesa), Linux kernel 5.2.3, latest SteamVR beta + Proton 4.2

@yaomtc try the new proton 4.11-1
I personally am using the Valve Index without controllers in Whirligig. (The controllers were not even on when I used it yesterday) If the ui is just out of reach you should be able to shift your playspace with OpenVR-AdvancedSettings. Or there is probably a button combination for resetting the view.

Thanks, the issue is gone in 4.11!

For me it's not only the videos that have bad performance, it's the whole program ! Navigating through the menus with Whirligig freshly installed and no video loaded is already painful or impossible. What is your experience about this ?

For me personally, the program itself runs as good as on Windows. "Only" video playback is slow.

I just tested on a monster rig and indeed it doesn't have any issue without video playback... My i5-4690K may be the problem.

I can no longer access anything in my home folder from Whirligig or from Skybox (#3896). Here's my launch options for each:

STEAM_COMPAT_MOUNTS=/home/myusername/:/mnt/WD1TBlue/ %command%

I figure this has to do with the sandboxing of Pressure Vessel but I'm not sure... this used to work but it doesn't anymore.

Hello,
I'm wondering if proton can handle video acceleration for decoding?
I noticed that whatever the video path i'm choosing in whirligig, my CPU is used instead of GPU.

EDIT: actually the only usable video path is direct show. The other ones either doesn't work or lag crazy.
But directshow still hit the cpu instead of gpu.

My GPU is an RTX 2080.
Driver Version: 525.60.11

I don't think so, this is the latest news I could find:

Skybox has better performance for video, I would recommend using that or vr-video-player: https://git.dec05eba.com/vr-video-player/about/

I do think so.
By monitoring resource utilization, i can see my gpu staying close to 2-5% while the cpu jump to 50% on a 16 cores,

I appreciate the mention of alternatives, but I think you are missing the point of what issues on Github are for.
In this particular case, it's about having Whirligig running properly using Proton.

What? You asked if Wine has support for hardware accelerated video. I told you it doesn't, as is demonstrated by your GPU utilization... There's no indication that there's work being done to fix that, so I gave you a workaround.

I don't know why i understood your previous post completely sideways. My bad...

Anyway, i hope this recent implementation of video acceleration in Vulkan would be useful for Proton/Wine and at the end Whirligig:

Looks like Unity (engine used for Whirligig) still only supports DX11 on Windows, Vulkan support is only on Android (like the Quest)

Yes, but isn't it the role of DXVK (and by extension Proton ) to translate DX11 calls to Vulkan ?

DirectX 11 doesn't seem to be relevant to video playback, that's the job of DXVA (Media Foundation integrates it), which Wine does implement (translates to VA-API) but I'm not sure if it's working with Whirligig, not sure how I'd troubleshoot that...

Does not launch with Proton 8. Proton 7 works.

Unlike with SKYBOX, Whirligig only seems to crash on launch sometimes. Not every time.

steam-451650.log

For me it crashes if the previously launched app/game, cough cough skybox, crashed silently.
After restarting only steamvr, I'm able to launch whirligig without problem, even with proton 8.
