Magpie VS wine

depending on the game, fsr(or dlss if you have the option) may be available in options to help you out, otherwise you could give a free option a go, such as Magpie

For games that won't go full screen, at least we have Magpie as a last resort. The experience won't be as seamless though...

Another thing you can try is playing the game in a borderless window at a lower resolution and using Magpie to upscale it to fullscreen. Magpie offers a variety of upscaling options that can produce a less blurry image than the bilinear interpolation that is typically done when upscaling by the GPU or display.

Configure VLC to play the video in an extra window with the same resolution as the video source and upscale the window to fit the screen. On Windows 10 the FSR upscaling can be achieved with Magpie. On the Steam Deck the system built-in FSR/CAS combination is used.

Something else that may also be of interest is Magpie. It's a tool to upscale windowed content into fullscreen with a variety of upscaling methods available.

also using enabled antialiasing in game settings (or even globally set in video driver) consume much less resources then rendering full size bigger resolution image for reducing aliasing. there are also such tools like Magpie (https://github.com/Blinue/Magpie/blob/main/README_EN.md) or Lossless Scaling tool from Steam. they enable FSR supersampling to any game on any GPU.

To everything that the community has said, I also want to add that No Man's Sky has FSR tech (the game runs at a lower resolution and it's upscaled). You can use Magpie or even better, Losless Scaling to create a similar effect in SC and win some extra frames :)

Much like it did before this commit.

Both Proton and Wine are open-source, there's not much to be gained by trapping any possible development to only folks working at Valve when there are thousands would happily help for free, on top of those Valve already pays.

Valve doesn't use upstream Wine. They use their own fork: https://github.com/ValveSoftware/wine

The 'No GPU Found' error is caused by https://github.com/ValveSoftware/wine/commit/51ce414a1f41fcaa415c4d3b4edd6b96ba711a35

Here is a github issue that describe it better https://github.com/ValveSoftware/wine/issues/177

Looks like Proton Experimental just fixed it. https://github.com/ValveSoftware/wine/commit/ae2fad7338cc2f914536469656448ecb5fdcf294

I'm pretty sure Eggroll is reffering to this Gnome 43 specific ALT+TAB fix which was merged in Proton Experimental last week: https://github.com/ValveSoftware/wine/pull/169

A solution is in progress. Give it a few weeks, or build Proton yourself. https://github.com/ValveSoftware/wine/issues/172

Then, if you managed to attach gdb, source this script and run lsf. After that let the game continue until you hit the crash and you should be able to get a backtrace with symbols (don't forget to use a radv build with debug symbols left in.
