Is there anyway to “upscale” old 640-480 games?
Right now you either get a tiny box you can’t see or a pixelated mess.
Gonna need more information here
Are you playing PC native games? Run them through dosbox to get access to its scaler and settings (you can run windows 95 in dosbox if needed)
Are you running emulated games? Jump into the video settings and adjust the scaling configuration
Are you running console games? Gonna want to get an OSSC or retrotink
Edit: just seen the post title says PC, dosbox is your solution then
If you’re using Windows, DXWnd has some options for improving the graphics in games. It may not work for every game but it’s probably worth checking out.
It’s a matter of time before we can use real-time AI upscalers. Nvidia (et al) have been working on this quite a bit.
In the mean time, the two options you mentioned are it.
If you are on Linux you can use gamescope. It has FSR 1 built-in.
Personally I would take the pixelated mess over any upscaling any day. It’a either blurry or just plain wrong.
BorderlessGaming lets you force a window to scale to a specified size.
Those older games look better on OLED or CRT screens if you have any.
you’ll need to research the various games to see if someone made a HD mod pack for them.
Check that when the game is in fullscreen it sets the monitor resolution correctly. Sometimes it’ll stretch the game in software and look goofy.
Alpha Centauri from Fireaxis games has some downloads available to make it run on a 4k setup.
Dosbox
You can always just turn your screen resolution down.
