Does rapidly changing fonts cause any performance issues?

Does rapidly changing fonts cause any performance issues?

Assuming that your fonts are stored in local variables and not being generated every tick/draw frame, I don't see why it would cause performance issues. I guess it kind of depends on exactly what it is that you're doing though.

One way I can think of that would probably be pretty efficient would be to set a font using:
Next, you could use:
to draw your text somewhere on the screen according to the font that you set with the first function.

You could also use:
to create a new drawable text object and simply draw that with a love.graphics.draw call.

https://love2d.org/wiki/love.graphics.print
https://love2d.org/wiki/love.graphics.printf
https://love2d.org/wiki/love.graphics.newText

I hope this was clear and helps!

There won't be any performance issues as long as you aren't creating new Fonts every frame. Both love.graphics.newFont and love.graphics.setNewFont create an entirely new Font object, so avoid calling either of those in love.draw or love.update.

Ah, well forget about my idea then.

Just a slightly different approach to font changes.
Excuse extra material as I was just playing around with shaders.
