NVIDIA 440.66.17 Vulkan Beta Driver released

By - | Views: 13,259

Today NVIDIA have released a fresh developer-focused Vulkan Beta Driver with support for more extensions and a little performance work included.

On the extension side, as of 440.66.17 the NVIDIA driver now supports these:

It's interesting to see VK_EXT_external_memory_host finally land in the driver, as it's been around since 2017 according to the linked spec. What does it do? This extension enables an application to import host allocations and host mapped foreign device memory to Vulkan memory objects. As for VK_EXT_extended_dynamic_state, that was made available at the end of 2019, adds some more dynamic state to support applications that need to reduce the number of pipeline state objects they compile and bind.

On top of that, NVIDIA said they've also improved performance of vkCmdMultiDraw*IndirectCount on Pascal and earlier GPUs. See the Vulkan Beta here.


Reminder: you know it's a special Beta driver thanks to the additional two numbers on the end of the version string, with the newest stable version of the NVIDIA driver for Linux at 440.82 which released on April 7. This special Vulkan beta driver is where all the shiny new stuff goes in before making its way into the stable release for everyone. Really, it's mostly aimed at developers and serious enthusiasts. Unless you need what's in them, it's generally best to wait for the stable drivers.

And we Ubuntu users still don't have a repository for experimenting with these beta drivers.

yea seeing it is not as easy grabbing these drivers.i mean yea if you have an arch based system you can get them.but ubuntu should be giving access to this.

Check out the very first link in the article. The one that says "Vulkan Beta Driver"

Install Ubuntu with / on ZFS, snapshot, install the Nvidia drivers outside of the package manager, do your experiments and then rollback. That is the best people can do until a PPA is made.
In Arch or based it is easy to install thanks TK-Glitch, but in Debian and based we need a repository that will facilitate the installation of these drivers.

Whenever I try to install I have problems with OpenGL libraries like libGL or libGLU

The link was added to the article afterwards, at the time I had read it, it wasn't there. I even removed that part of my post.

Reinstalling your whole distro just to install some drivers does not look like "the best people can do" by any means, lol. I guess it would be less trouble to package it myself.
I don't use (nor do I plan to use) zfs. But instead, I use LVM for all my PCs, so I could do LVM snapshots too.

You still need to apply some unofficial patches if you want to use kernel 5.6 or 5.7 though. I've just done this on my Tumbleweed system and the drivers installed fine.

Yes, apologies, I noticed after hitting publish and coming back to it that I forgot the link so I added it in twice. In future, if we do forget something, be sure to use correction report feature as that sends info to us directly that we may miss in comments. Cheers.
I wonder when (and if) Nvidia will release a new stable driver.
