	shaders are used to compute complex per-pixel lighting and coloring.
	In some games the use of pixel shaders is optional, and disabling
	them can result in faster game play, albeit at the expense of
	graphics quality. Other games may not function at all without pixel
	shader support.  This functionality is provided via either the GL
	Shading Language or the ARB_fragment_program extension, so not every
	video card that has the ability to render pixel shaders under
	Windows will be able to process pixel shaders under Linux. This is
	important to note when you are purchasing a game, since a game which
	lists a Geforce 3/4 or Radeon 8500 as its minimum video card may in
	fact require pixel shaders, which aren't available in Cedega with
	anything less than a Geforce FX series card.</FONT></P>
