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.

Yes of course but it gotta start somewhere. Not too long from now those generations are seen as old and outdated.

That would be fair(-ish) if the current market wasn't completely f*.

Even "old" geforce 10xx series cards are still quite expensive in the used market.

I applaud AMD's effort to provide an open-source, accessible, vendor-agnotic, easy to implemenet tech, usable even by older graphics cards.

It's fair. There's always a cut off for new technology.

I'll have to save for a while. Last time I looked, I could sell my used 1070Ti at a profit compared to what I spent to buy it, lol

It's actually pretty depressing how many of these went for the proprietary option. I suppose it got a head start, but still.
Are these features available for Lutris too?

Looks like this story is similar to CUDA vs OpenCL where we have two solutions but only one of them is really good but it's proprietary.

Quoting: needlessoptionsCool, I don't think there are any DX11 games with DLSS though because on Windows it's only supported on DX12
Wrong. DLSS supports DX11 https://developer.nvidia.com/dlss-getting-started

oh ok cool

In this case though, FSR is superb. Apparently DLSS is "better" (they use very different methods, I think), but again, proprietary, and only works on Nvidia. Frustrating.

And isn't FSR sort of . . . more broadly applicable? 'Cause, like, doesn't DLSS have to be "trained" on a per game basis? Whereas, doesn't FSR not have to do that? So in theory, FSR would work with any game, whereas DLSS would work on (any game whose devs have made the effort to "train" DLSS on their game).
