Borderless-Gaming VS nyrna

You can. I use it to persist settings in my app Borderless Gaming https://github.com/Codeusa/Borderless-Gaming

This and this work, but they mess up OBS recordings so I stopped using them

Yes you can do that with any ultrawide. Simplest way is to just play windowed mode with a 16:9 resolution. If you want it to be 16:9 borderless windowed in the center of the screen you can use BorderlessGaming with a "Set window size" config, though that approach can be a bit inconsistent sometimes.

I don't know if its a fix, but Try grabbing Borderless Gaming. See if you can force it into a resolution you want. I would try it myself but...

Turn off screen rotation lock and rotate the display so it's portrait. This allows us to launch the game without issue into windowed mode (it's full screen landscape that's the problem). Now rotate the screen back to landscape, game will still be running in a window. Now use Borderless Gaming (or your favorite borderless window full screen app) to make the window into full screen. https://github.com/Codeusa/Borderless-Gaming/releases/tag/9.5.6

You could try Borderless Gaming - Free version BorderlessGaming9.5.6_admin_setup.exe - July 2019: (https://github.com/Codeusa/Borderless-Gaming/releases/tag/9.5.6)

Borderless Gaming is another free alternative that doesn't do anything fancy like improving the image quality but can also do the job of making your games fullscreen: https://github.com/Codeusa/Borderless-Gaming/releases

Someone pointed me in the direction of "Nyrna", which looks promising! https://nyrna.merritt.codes/ (Can download a free trial from the MS Store)

please try https://github.com/Merrit/nyrna and let me know how well it works.

It currently only works on X11 but Nyrna seems like it's made for this use case

Nyrna - Used for suspending the active application with a hotkey

If on PC, recommend using Nyrna : https://nyrna.merritt.codes/ . You can set the hotkey to the Pause/Break button on your keyboard, and it will force the current application (eg Hogwarts Legacy) to pause midcutscene and show the desktop till hit the hotkey again.

Here's an application for Windows: https://github.com/Merrit/nyrna

- Download the application "Nyrna" from https://nyrna.merritt.codes/. Download page located in the top right, select the version for your operating system (for this guide, I am using Windows 10)

But there is maybe a way to solve this problem. While looking for a solution i stumbled over the programm Nyrna which allows to suspend programs. You could in theory freeze the game at one point and send your computer in stand-by / hibernation and continue the next day. But i have not experimented much with it.

There is a 3rd party program, Nyrna. It lets you pause any game at any point, keep it in RAM without using up any other resources, then get back to it whenever you want to.
