Quoting: dubigrasuWhile I don't dismiss what Ethan says, I'm more inclined to side with Gordon.
I think valve plays the long game here, we have a saying: befriend the devil until you cross the bridge.

I hope the same, but until then, what should Ethan do if devs aren't hiring him for a while? Let's hope there will be enough devs and/or publishers to contract him until the bridge is crossed.

A feature that allows to import and/or exchange library folders without restarting the Steam client is now kind of mandatory.
You might have several SD cards holding libraries, or when docking you want to have the external storage accessible immediately to make it a smooth experience.

Gosh, I. can. not. wait. :D

Quoting: MatomboEven if it was the windows version it wouldn't technically go through 2 compatibility layers at the same time but in parallel...

Hmm... imagine a powerful ARM Steam Deck... with ARM Linux, ARM Steam, ARM Proton... maybe it'll allow for even better performance in a small handheld.

Oh, that means their in-house Anti-Cheat solution was not really a show-stopper, just crashed? I expected Quake Champions to be unplayable for Proton users in the forseeable future, but this is nice to see. I think I saw something about certain stubs in wine missing and kernel 5.11 needed to make it work again. But having this officially now in Proton is great!

So, with EAC hopefully working until end of the year, videos using media foundation codecs kinda working already now (due to transcoding the video and delivering it via cache) there is still one major issue left: CEG. There are several games not working with Proton and the Linux Steam client using CEG (custom executable generation drm), which do work fine with Wine Steam (e.g. via Lutris). Though I guess I'll be installing Lutris on the Steam Deck as well, I kinda prefer not to have also Wine Steam needed, as the Lutris Wine Steam version has issues for me with friend list not loading (thus friend invites not working), Store, Community and Browser not working etc. Fingers crossed this will also be addressed.

Erm? Windows games, on ARM and Linux? So they have to go through 2 compatibility layers? Or am I missing something here? Like, did they create a native ARM version for Wolfenstein Youngblood?

edit: ah okay, in the video they state: "An ARM based version of the game is not planned for commercial release"... so yeah, they ported it. Impressive

Waiting for the driver to arrive in the PPA again :D
Also hoping for less jitter with async reprojection in VR... I mean it should be "stable" now, right? ^^

The strong jittering/latency is definitely introduced with and caused by the new async reprojection implementation, but the games themselves are now butter smooth when turning your head. Controllers might be visually affected by the jitter, but accuracy is not.
If you turn down the grid to e.g. floor only the issue can be mitigated, and as you probably won't have to open the SteamVR Dashboard that often, I still think that having async reprojection active will give a better experience overall.

Additionally I had to deal with an issue, that after closing SteamVR it wouldn't render in the HMD anymore after a new start, but the vrmonitor or vrcompositor window rendering the content on a desktop window, and stating the HMD wouldn't be in direct mode.

Turns out, that for me the detection of the HMD fails after closing SteamVR. It can come back by just powercycling the HMD, but that didn't help for me anymore. Even a reboot didn't help. In the vrcompositor.txt logfile, you could see that SteamVR fails to find the device.

Christoph Haag created a little tool, that queries the devices via vulkan api: https://github.com/ChristophHaag/vkdisplayinfo [External Link]

vkdisplayinfo
=============
instance extension VK_KHR_get_display_properties2 is supported
instance extension VK_KHR_surface is supported
instance extension VK_KHR_display is supported
Using vkGetPhysicalDeviceDisplayProperties2KHR
physical device 0 has 2 displays:
Valve Corporation Index HMD (DP-0) (0x564709f9cfc8) 2880x1600
AU Optronics Corporation (DP-2) (0x564709f9dd98) 1920x1080

With that tool I can check before I start SteamVR if my HMD is detected. If not, I can make it re-appear by powercycling the HMD (doesn't work each time though) or better re-attaching the display port cable. I'm not sure where this problem comes from, might be nVidia driver, might be SteamVR, might be my Displayport to Mini-DP converter. But I downgraded the nVidia driver down to 435 (also tested with 440, 450 etc in between), where I never had that this issue, and even there it happens today. So I think Steam client or SteamVR is at least involved as well, as I cannot downgrade those. Yes, I tested even Windows to make sure the device itself wasn't broken, there was no issue at all.

Despite these issues, I don't want to miss being able to play and enjoy VR on Linux ;)

Quoting: leillo1975Do you report it?

I've answered to Alberto's eMail he send me pointing to the new experimental repo, where I mentioned I'm waiting for the 32 bit packages to be whitelisted, as I guess he's probably aware of the issue. In the rare case he's not, I hope this was a nudge making him aware it's currently missing :D

edit: looks like 32bit is now in (has been for 18.04 and 21.04, but now also 20.04):

Looks like the little nudge helped ;)

Quoting: leillo1975Alberto Milone has just replied to an email and created this PPA (totally experimental and use it at your own risk):

https://launchpad.net/~albertomilone/+archive/ubuntu/nvidia-testing [External Link]

Unfortunately I can't try it today due to lack of time, but if anyone does, please let me know how it worked.

Just installed it... but now Steam crashes on startup.

edit: Looks like same issue when 465 came out, 32bit is missing.

Quoting: slaapliedjeI mean this is a BETA driver, so keep that in mind...

True. Tough they created a special dev PPA for the dev version of 396.54 back then, which had the VK_EXT_transform_feedback. Which was also huge as games like The Witcher 3 started to render correctly.
As 470.42.01 has some really big features, I hope they can bring it either via a beta PPA or just integrate it into the normal PPA and upgrade the driver as soon as it's not flagged as beta anymore.
