When set to 0, use regular 8x8 tiling format for the framebuffer, compatible with textures. When set to 1, use a 32x32 tiling format. To untile the color buffer when using this format, use bit 16 of the [[GPU/External_Registers#Transfer_Engine|display transfer flags]]. It is unknown if there are any advantages to using the 32x32 format. | |||
