I actually find that starting a 'raw disk partition' virtual machine for Windows is one of the best ways to run it. Stops it from fucking up your BIOS and EFI when it does an update. You can restart into it when you want the 'native GPU' for games.
Of course, the even better way to stop Windows from fucking up your hardware is to not allow it anywhere near your hardware in the first place...
Speaking as a developer; I've a 4K screen which is amazing for having loads of source files open at the same time, and also works for old or undemanding games. Glorious Eggroll's version of Proton has all the FSR patches in it, so you can 'upscale anything'. Almost any modern game, I'm going to be running at lower resolution, usually either 1440p or the slightly odd 2954 x 1662. Generally, highest-quality graphics and upscaling looks better than medium-quality native to me, for games where I have to compromise.
I would be interested in an 8K display for coding, as long as the price is reasonable. I'm not spending five grand, that would be crazy. But I'd still be upscaling for playing games, as basically no GPU could drive that many pixels.
