NVIDIA announced today an expansion of RTX and DLSS for plenty of Windows games, and for Linux users there's something exciting coming too: NVIDIA will hook up DLSS with DirectX 11 and 12 with Proton in September.
What is DLSS? NVIDIA DLSS (Deep Learning Super Sampling) is an AI-powered rendering tech to help increase performance for NVIDIA GPUs using their dedicated Tensor Core AI processors. It helps to boost framerates by rendering frames at a lower resolution and then it's made to look much crispier using deep learning.
Currently DLSS on Linux with Proton only works with Vulkan titles but that's about to change in September. In their announcement they said:
Recently, we launched support for NVIDIA DLSS in Proton, enabling Linux gamers to play Vulkan API games with NVIDIA DLSS, including DOOM Eternal, No Man’s Sky, and Wolfenstein: Youngblood. Next month, support extends to dozens of DirectX 11 and DirectX 12 games, including Control, Cyberpunk 2077, Death Stranding, F1 2020, Mechwarrior 5: Mercenaries, and Necromunda: Hired Gun.
Stay tuned for further details.
Some of the work is live now on GitHub in Pull Requests to get it all working with Proton:
- dxvk-nvapi - "Nvapi: add new NvAPI implementation"
- dxvk-nvapi - "Implement the required NvAPI entrypoints for D3D11 DLSS support"
- VKD3D-Proton - "vkd3d: Add new interfaces: ID3D12DeviceExt, ID3D12GraphicsCommandListExt"
- DXVK - "Implement DXVK pieces required for DX11 DLSS support"

I'd say for handhelds that have relatively low resolution in general, upscaling is not so useful.
I'd say depends on, if you have to upscale from a let's say steam deck to a 4K or 8K monitor in your living room ... if you can connect them (?)... may be useful.

Quoting: ArtenSo... nvidia hopes, that somebody choose their GPU for deck like handheld with steamOS? Ot they planing to make one?

May be related to this, in some way?

Quoting: elmapulsome one really want to be the chosen one hardware provider for steam deck 2...
Nvidia can present a decent argument for choosing them - let them upstream their driver and provide open source OpenGL / Vulkan implementation. Let's see when that will happen.

i think they would only do that if amd start stealing their marketshare at an ridiculous speed, or if it slowly get to 51% of the marketshare.

Quoting: ridgeSo, does anyone know if this can be implemented in "vanilla" Wine as well, or is it only a Proton thing? I don't want to use Steam, and some of my games such as No Man's Sky does indeed support DLSS.
It should, since the bulk of the work is for vkd3d-proton which you can use in lutris/tkg/wine-ge/vanilla wine etc

It maybe related. But this is about integrating it into Proton for windows games mostly on X86-64 architecture. Games are demanding not only for GPU, but also for CPU. So nvidia need CPU like M1 from Apple which has X86-64 like memory-ordering model in silicon as alternative for ARM memory ordering mode. It speeds up Rosseta 2 translation, because Rosseta 2 has one big problem out of the way. Apple don't give them M1, so nvidia need make something similar in-house.

Proton or Wine also needs https://github.com/ValveSoftware/wine/pull/119 next to the PRs mentioned in the OP.
Wine-staging already has `nvcuda`.
As far as I know, the already available 470 driver should be sufficient.
