How do we .. choose different video

I have multiple video drivers listed in my device manager, the SDK always uses the first one in the list, I want to use either the second or the third in the list. What method do I use to tell it to use a different driver? The first driver (and sometimes the second) are virtual drivers, the physical driver for the real video isn't until the second or the third.

You can use this function, it takes the index of the driver you wish to use.

Blitz3DSDK.SetGfxDriver(driver_index);

Also, the following functions can be used to obtain information about the driver(s)

Blitz3DSDK.GfxDriver3D(driver_index);
Blitz3DSDK.GfxDriverCaps3D();
Blitz3DSDK.GfxDriverName(driver_index);
