NVIDIA R535 Linux Beta Brings New Vulkan Extensions, DMA-BUF v4 Wayland Protocol

[dreamcat4]

Once this driver is packaged for Kubuntu 23.04, I'll give it a quick whirl to see how much improved it is, but sadly I suspect I'll not be able to switch to Wayland full time on systems where Nvidia is the primary GPU for a few more years.

Well maybe we will get a slow progress, but i would hope that a 2 year time horizon is not out of the question... also maybe nouveau drivers can improve too during this sorts of timeframe, with getting the GSP firmware interface (or whatever its called). Not to be downclocking the GPU

and still there is no support for DLSS 3 ... massacre: / Nvidia get a grip !!!!

you say that but 3 is no good.... 2 is where its at and that isnt on nvidia afaikt its on wine / proton / other associated projects right?

now nvidia could help by giving resources, but then again if somebody else can do those. then an actually nvidia engineer resources would instead be better allocated to working on the drivers stacks. for which cannot be done by other devs

What do you mean there isn’t support? DLSS 3 has had Linux support since it was first released. Issue is that Linux gaming is dead and no developers make native titles.

Seems like you want Nvidia to waste their resources to help translation layers.

Can you point to a reliable source that verifies that DLSS 3 works natively on Linux?

Otherwise it's true that DLSS 3 doesn't work yet with Proton for Windows games on Linux, however DLSS 2 already works for some time now thanks to DXVK-NVAPI, which nVidia explicitly added support for on their binary Linux driver side, too.

But I thought DMA-BUF was GPL-only, wasn't it? How did they sort this out?

That was sorted out many, many years ago, December 2012 to be exact. Nvidia wrote some helper functions that allow use of dmabuf without needing to go into the internals of the kernel. See here:

Sorry that wrong Gusar the 2012 stuff does not get you to v4 DMABUF.

https://developer.nvidia.com/blog/nvidia-releases-open-source-gpu-kernel-modules/

Nvidia open sourcing their kernel module under MIT/GPL does.

Some of the issue with Nvidia come about from the limited allowed DMABUF interface the closed source module can use.

What a waste of resources are you talking about - optimized Linux already provides better performance than Windows 11 in many cases ... in native Windows titles ... so that's what we expect = Proton support via dxvk-nvapi.
