I can't give you an accurate answer because it's been an ever developing project of mine, improving more and more in each game I start. I guess I could say it took maybe 1-2 hours to get the very first version up and running, and I've been tweaking it here and there ever since.
Quote: "Just out of curiosity, how much slow-down do you actually get when having an overlay like that?"
The console window slows down the game at a surprising rate actually. When it's full of text, the game slows down to about 30 fps, without it, 200 fps.
Do you think cloggy's D3D text plugin would perform better?

Thanks!

Yeah, it's really useful for debugging stuff without recompiling.

Aw crap, did I really?
Quote: "After seeing that I'll have to figure out a fast way of drawing text now onto images. I'll probably use a bitmap (or converted to) font."
You could generate one big image in your loading section by drawing all characters to a bitmap and grabbing the images, and during runtime use
Image Kit's IK paste image ib image <img> <x> <y> <left> <top> <right> <bottom> command to paste whatever character to an image. It's super fast, it's what I used to draw the minimap.
