Compensate for applications that do not understand transparent pixels in the overlay. This option is available when Overlays are enabled.
Sets the amount of AGP memory allocated to the graphics board (in kilobytes). AGP memory is used for a number of purposes so it should be left at its default setting (16384 kilobytes). If you want to disable it, set the size to 0. Increase the size if you are using a large number of AGP textures.
Sets the amount of memory allocated to the graphics board for command buffers (in kilobytes). DMA memory significantly improves performance for cards that use it. If there is a need to disable it, set the size to 0. Otherwise leave it at the default setting (2048 kilobytes).
