Many games give the option to run in either 16-bit or 32-bit colour depth.
This refers to the amount of video memory that is required for each screen pixel. 32-bit colour depth gives a larger range of colours to use, resulting in higher quality rendering.
Due to the increased video memory bandwidth that is needed, 32-bit colour will reduce the frame rate for the game.
With some games, this can result in choppier performance.
* Intel® 82810E and 82815 graphics controllers support up to 16-bit colour textures
