Using the -v Option to Choose a Video Driver

You use the -v option to load a different display driver at startup. This option overrides the setting in 3dsmax.ini.

Follow the -v with one of these choices for the driver you want to use:

o: Loads the OpenGL driver.

d: Loads the Direct3D driver.

x: Loads the Nitrous driver. Follow the x with one of the following:

• 9 (-vx9): Nitrous in Direct3D 9 mode.
• 11 (-vx11): Nitrous in Direct3D 11 mode.
• s (-vxs): Nitrous in Direct3D 11 mode with WARP.

n: Loads a null driver.

For example, if you ordinarily run Nitrous using Direct3D 11 (the default display mode) and want to switch to Direct3D 9 for a session, you would type: 3dsmax −vx9
