A (very) simple torch flame demo. Shows 100 flaming torches on screen. As you can see by my screenshot, I was able to run this at 450+FPS.

This is a simplified version of my flame routine in my Sorcery game. It's not doing anything big or clever, and it's not particularly realistic, but it gives a pretty good impression of a fire (changing the colours in the animation strip might make it look more realistic, but I needed a cartoon-styled flame to fit my game).
