I was quite surprised to find out the Elgato Cam Link 4k HDMI capture supports undocumented input at 640x480 1024x768 and 1600x1200 uncompressed at 60 fps (800x600 does not seem to work). This, combined with my Gefen VGA to DVI Scaler Plus seems to give good results (to me) even for 320x200 output from a Voodoo 3 VGA in DOS (when scaled to 1600x1200).
