Only a few days ago Proton Experimental saw an update to pull in NVIDIA DLSS support for DirectX 12 and as of today's update this has expanded to DirectX 11 titles too.

It's still currently disabled by default with you needing to make a small adjustment to turn it on. This can be added to individual games by setting PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 %command% in the launch options. Or you can try PROTON_ENABLE_NVAPI=1 %command% with "dxgi.nvapiHack = False" in a DXVK config file.

There's also an update to newer DXVK that includes the latest development work and you should find that Monster Boy and the Cursed Kingdom is now playable with it. The Proton changelog can be found here.

Need to know how to actually use Proton Experimental? Here's a simple HOWTO (as it's not complicated!). Make sure it's installed by searching for it in your Steam Library, then select it from the Compatibility menu in the Properties section of a game. See our quick video below:

For an explainer in text form:

  1. Search for Proton Experimental and install if not already.
  2. Right click any game on Steam and go to Properties.
  3. Select the Compatibility menu on the right side.
  4. Ensure the "Force the use of a specific Steam Play compatibility tool" is ticked.
  5. From the dropdown box that appears select Proton Experimental.

By the way, what is DLSS ?

It's a weird new-ish graphics technology. Far as I can tell, it lets you run stuff at lower resolution and then kind of pretends they're higher resolution again, giving you the high-res level of detail, almost, but for much less processing cost, so you can get a better frame rate. It and another similar tech (one NVidia, one AMD) were kind of introduced to let computers run ray-tracing at faster than a crawl, but it has much broader applicability.

.. And what's not to like about THAT! :)
afaiu this technology should have the potential of seriously extend the life span of a graphics card. I so totally love this.

Provided you have a newer card to begin with. Per the article it's only for 20xx and 30xx series cards.

I must jokingly admit, I'm a little jealous I didn't wait a year and got a 1070Ti instead, lol

I'm playing Cyberpunk right now, at 4K, at a stable 60fps, when I couldn't even get 60fps at 1080p before FSR (which is loosely/broadly AMD's "version" of DLSS). I go in-game, stick the resolution down to 1600x900, and FSR kicks it back up to 4K again. Yes, you lose the sharpness a fair bit - especially when you go below 1080p on a 4K screen... but c'mon! Cyberpunk at 4K at 60fps... even with the grain FSR introduces, it's just... stunning.

(Note that the video is captured in software, so does occasionally blip down to 55fps, but when not recording, it's smooth as butter - so satisfying).
Cool, I don't think there are any DX11 games with DLSS though because on Windows it's only supported on DX12

Have been really looking forward to experiencing DLSS having been stuck with a GTX 1070 for 5 years, however I just could not justify £1400 for a RTX 3080 so I bit the bullet on a RX 6800XT as I could not wait any longer and boy am I impressed. I have yet to try FSR (AMD implementation of DLSS) but so far getting between 60 and 120 fps at 4k in most titles so have not yet had the need to try it. I can however use FSR with my 1070 to help extend its life in my backup machine.

My only annoyance that I only just found out about is that AMD cards do NOT support HDMI 2.1 due to HDMI driver being closed source. Hopefully AMD can release a closed driver as an add on, maybe? as I have a 55" TV that I cannot enable Freesync or VRR on. Anyone looking for a new GPU should be fully aware of this limitation and choose Nvidia if this feature is a must.

Wrong. DLSS supports DX11 https://developer.nvidia.com/dlss-getting-started

Yes of course but it gotta start somewhere. Not too long from now those generations are seen as old and outdated.
I have a spanking new card myself, costed me a kidney and a half, and knowing that this card will be usable for X additional years thanks to this technology really is a major relief.
