Doom 3 - Heat Haze
This next demo was recorded in order to test a specific effect in Doom 3: that cool-looking "heat haze" effect that you see whenever a demon hurls a fireball at you. We figured this effect would be fairly shader intensive, so we wanted to test it separately from the rest of the game.

The relative performance of the cards doesn't change much in this demo, despite the abundance of shader effects.
