Description
This option selects which system MAME uses to draw it's graphics.
Example
mame <gamename> -video d3d
Command Format
<gamename> -video <system>. The system can be gdi, ddraw, d3d or none. D3D is the fastest with the others there for compatability on older systems. The example will run MAME using Direct 3D to draw it's graphics. For D3D you must have a Direct 3D 8+ compatible graphics card. If you don't then use ddraw or gdi. The none option produces no graphics at all which is great for benchmarking.
