ZDoom

No, it works (at least vanilla Doom does), but it's not a perfect 60 FPS. But it's still playable if that doesn't bother you.

Is 4k using the software renderer impractical on the average pc? I recall being told that it's a lot of pixels to push around, but nothing more than that.

It would be just as easy to to as 2x scaling, but you are forgetting something: The linear filter cannot filter this down to the display, you'd have to do it in multiple steps. Also, with today's screen sizes this very quickly becomes unmanageable. Not worth bothering.

I do a lot of tests that require putting a load on the gpu that's higher than maximum resolution (particularly with boom/vanilla maps) and was just wondering if this would be easy to implement if the scale function is in there already.
