The game I'm working on is designed for 1920x1080 and automatically scales to whatever resolution you're running it at. Naturally for 1920x1080, I need a fairly big font (32 point seems to work nicely) but if someone is running at 640x480, a 32 point font is far, far too big. Now I can't possibly load a different font for every possible resolution out there, but I can't find a way to adjust text size either. This seems pretty elementary. Presumably fonts are loaded into a texture, and drawn from the texture. So there should not be any speed hit from scaling them, and I can scale everything else which is drawn from a texture, but I can't find the trick for fonts.
Surely there's a solution for this. People can't be having enormous fonts on very low resolutions, or vice versa.
