It dedicates a certain amount of VRAM to caching textures. The larger it is, the more textures it can cache and the less it has to keep reloading the textures, so you get less popping, BUT the less VRAM is available for drawing and rendering the image to be displayed, so if it is too high your graphics will become crap. 5,000,000 to 10,000,000 is a good range for good machines. I once tried 100,000,000 just to see what it did.... that was not fun. As you increase it in a certain range it will IMPROVE quality, but if you go too high it will begin to DECREASE.
