antimicro VS Magpie

If you're wondering how to do it yourself, I use Antimicro to map controller inputs to keyboard keys. (green to A, Orange to K, everything follows in between, and strum to L)

Read in the comment section where VR and controller was discussed: "What I do is use AntiMicro: https://github.com/AntiMicro/antimicro/releases , which allows you to map keyboard inputs to your controller, instead of using the games controller input. This way, you can map one button on your controller that when held, activates another mapped set for the controller allowing you to use keyboard hotkeys. It also makes it easier to switch between using your control and the keyboard." So if there is a way to use the controllers maybe it could work.

AntiMicro

There is no native support for controllers for this game. However, you may use the program Antimicro to enable support for controllers, although I only tested with an Xbox 360, but theoretically it should work with others.

Par ici -> https://github.com/AntiMicro/antimicro/releases

bind it to a key combo alt space?) and use a program to fire that combo on joy press (like voiceattack or antimicro https://github.com/AntiMicro/antimicro/releases/tag/2.24-final )

To play with a controller, you'll have to use another program. I suggest antimicro found at https://github.com/AntiMicro/antimicro. It hasn't been updated for almost seven years, but it still works for me.

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 :)
