Two big bits of news for Steam Play Proton today with two new versions getting released so let's take a look and see exactly what's new for the Windows compatibility layer.
Firstly, NVIDIA announced back in August that DLSS would come to Proton in September for DirectX 11 / 12. Well, their date was a bit off there it seems but Valve / CodeWeavers managed to pull in DLSS support for at least DirectX 12 in Proton Experimental as of September 30. To enable it you need to set PROTON_ENABLE_NVAPI=1, which you can do as a Steam launch option for games like PROTON_ENABLE_NVAPI=1 %command% (right click -> properties -> launch options).
Additionally this Proton Experimental release also fixes crashes in Project Wingman, Satisfactory and other Unreal Engine 4 games using the Vulkan renderer.
On top of that Proton 6.3-7 is also officially out now which includes these improvements:
- The following games are now playable:
- Life is Strange: True Colors
- Quake Champions (broken after a game update)
- Divinity Original Sin 2 (broken after a game update)
- eFootball PES 2021
- EVERSLAUGHT VR
- WRC 8, 9 and 10
- Fix Logitech G920 mapping for F1 2020.
- Fix Resident Evil Village display settings.
- Improve Forza Horizon 4 windowing.
- Update DXVK to v1.9.2.
- Update vkd3d-proton to include the latest development work.
Details can be seen on the official changelog any time.

- Cyberpunk 2077 (Steam version)
Does not work at all for me in the following:
- Control (Dx11/Dx12 - Steam version)
- The Ascent (Dx11/Dx12 - Steam version)
Has anyone tried with any of the games above?
Edit (6th Oct): after downloading Ghostrunner GOG Version (redeemable for free via Twitch Prime), DLSS works also there for me. I have just downloaded, built and deployed the latest master branch of dxvk-nvapi and followed the instructions there.

How did you get DLSS to work on Cyberpunk 2077, i tried with experimental proton version and the launch option but it still only has off as an option.

Made several attempts: deleted the prefix, take all the variables in the Launch Options off and then on again, and relaunching the game at each attempt.
Currently I have the following Launch string:
PROTON_ENABLE_NVAPI=1 %command% --launcher-skip -skipStartScreenOutcome is a little meh though:
