This is it. The big one! NVIDIA has today released the NVIDIA 470.42.01 beta driver which brings in lots of fun new things and further improves their Linux support.

Firstly, as promised, they've now added an NVIDIA NGX build for use with Steam Play Proton and Wine. This means Windows games and applications can use DLSS when run through Proton and Wine, providing they have been updated to support the features of this new driver. You should at least be able to try out the Windows versions of DOOM Eternal, No Man's Sky and Wolfenstein: Youngblood with this new driver and Proton, as they use Vulkan. DirectX support for DLSS with Proton arrives "this Fall".

Support for the VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT from the VK_EXT_global_priority extension was added, finally giving Linux / NVIDIA users asynchronous reprojection in SteamVR. For Linux users, you need the Beta version of SteamVR which added support for this as of version SteamVR 1.18.2 - so Valve were quick to have it readied.

Are you using or wanting to use Wayland? Good news there too. There's now "initial" support for hardware accelerated OpenGL and Vulkan rendering on Xwayland. However, there's some really fresh packages needed for it and some caveats too. You need DRM KMS enabled, Xwayland should be built from the current Git code as of at least commit "c468d34c" otherwise "it will fall back to a suboptimal path for presentation resulting in degraded performance", libxcb needs to be version 1.13 or later, egl-wayland version 1.1.7 or later and if you're on GNOME you need to have kms-modifiers enabled.

What are the Xwayland limitations? Currently it doesn't support the nvidia-settings app, there's no accelerated video decoding with VDPAU, no SLI / Multi-GPU, there's no "Frame Lock and Genlock" and also no "Front-buffer rendering for GLX applications". Hopefully now it's out, NVIDIA can focus on hooking up everything missing.

On top of that the "direct capture" mode for NvFBC "no longer causes flipping to be disabled for applications being captured", NVIDIA say this means G-SYNC can now also be used simultaneously with NvFBC direct capture.

More PRIME improvements too as well! Support was added for PRIME Display Offload where both the display offload source and display offload sink are driven by the NVIDIA X Driver, plus support for PRIME Display Offload where the display offload source is AMDGPU.

New extension support including:

  • VK_EXT_global_priority_query
  • VK_EXT_provoking_vertex
  • VK_EXT_extended_dynamic_state2
  • VK_EXT_color_write_enable
  • VK_EXT_vertex_input_dynamic_state
  • VK_EXT_ycbcr_2plane_444_formats
  • VK_NV_inherited_viewport_scissor

There's plenty more that's new including lots of bug fixes.

See the release page for more. For users on Arch Linux, TKG has updated their installer script.

Additionally, it was announced recently that Kepler-series GPUs being most of the 600/700 and some 800M would no longer see main driver updates after October 2021 and move to critical updates only.

Attempted to use the archaic .run file and gave up. Will have to wait for the package engineers shower us with the bleeding edge.

Funny old world. I still have an Nvidia GPU, but I just don't care about Nvidia news any more. Next one will be AMD for sure, though I'm not sure exactly when I'll be able to buy one, or when they will be available to buy for that matter. Damn miners

Is Doom Eternal good? Last Doom I played was the one from 2016 and I still haven't beaten it.

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.

2016 was pretty good, Eternal sucked.

I liked it. More difficult than Doom 2016, stingy with the ammo, you really have to use every gameplay element to beat it even on lower difficulty.

Alberto 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

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

I made a account just to say how excited I am for DLSS on Linux.

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

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