I would recommend using a tool - don't rely on your operating system or the game for upscaling. Lossless scaling works incredibly well for this. I'm currently playing FTL (720p pixel art game) on my 1440p screen and it looks magnificent with this tool set to integer scaling. Razor-sharp pixels instead of the blurry, mushy ones that it suffers from with its built-in upscaling.
None of this makes any sense with 3D games though, of course. You have to be blind to play 3D games at 720p on a modern display.
What's the point of using a lower resolution if not for demanding 3D games? Unless we're talking 240p for CRT gaming, but that's a whole different thing.
It only makes sense to use a modern resolution with a modern upscaling method like FSR4 or DLSS for 3D titles. Just turning the resolution down gets you a terrible experience, because these games were designed for higher resolutions. Details - including ones that are important for the player reading a situation, e.g. seeing enemies and enemy behavior - get lost in the visual noise from pixelation.
You can easily simulate this effect by watching a YouTube video of a modern title at a low resolution. With some recent games, even 1080p is actually too low.
What I really wanted to know was why you were using a lower resolution for 2D games, but it turns out you've already gone over that in a different comment.
IMO, low resolutions for 3D are still valid particularly if you don't have a recent GPU, and the idea that 1080p is "too low" for some modern games honestly really bothers me. I feel like 720p should be enough, and that developers are doing something wrong if they can't scale their UIs to fit that properly.
