Will this do the trick:

SetGraphicsDriver( GLMax2DDriver() )
If Not Graphics( 800, 600, 0, (DesktopHertz() Or 60) ) Then
	Notify( "Failed to initialize graphics", True )
	End
EndIf

Or does somebody have a better way?
Also does SetGraphicsDriver ever have issues? (Should I do the same for it?)

I have this:

Select renderer
	?Win32
	Case RENDERER_DIRECTX7
			SetGraphicsDriver D3D7Max2DDriver()
	Case RENDERER_DIRECTX9
			SetGraphicsDriver D3D9Max2DDriver()
	?
	?Linux
'	Case RENDERER_BUFFEREDOPENGL
'	SetGraphicsDriver BufferedGLMax2DDriver()
	?
	Default SetGraphicsDriver GLMax2DDriver()
EndSelect

_g = Graphics(realWidth, realHeight, colorDepth*fullScreen, hertz, flags)

?Win32
'on win32 we could try to fallback to DX7
If not _g and renderer <> RENDERER_DIRECTX7
	Throw "Graphics initiation error! The game will try to open in DirectX 7 mode."
	SetGraphicsDriver D3D7Max2DDriver()
	_g = Graphics(realWidth, realHeight, colorDepth*fullScreen, hertz, flags)
endif
'or to OpenGL
If not _g and renderer <> RENDERER_OPENGL
	Throw "Graphics initiation error! The game will try to open in OpenGL mode."
	SetGraphicsDriver GLMax2DDriver()
	_g = Graphics(realWidth, realHeight, colorDepth*fullScreen, hertz, flags)
endif
?
if not _g then Throw "Graphics initiation error! no render engine available."

"renderer" is an int-property read from an xml config, so adjust properly.

Yours will do too. But I think you could use "Throw" instead of "Notify" because you surely want your app to exit then (with no proper useable graphics mode).

Thanks man! Do you think SetGraphicsDriver will ever have problems? Should I do something like:

SetGraphicsDriver GLMax2DDriver()
If GetGraphicsDriver <> GLMax2DDriver() Then
     'Do Stuff
EndIf
