You mean in a window ? I never noticed that before, but indeed, in mode 3 the output screen is scaled/stretched like that..
Maybe you could use Graphics mode 2 instead of 3 ?
Graphics3D 640,320,0,2
Or use the Graphics command 2 times after each other:
Graphics3D 640,320,0,2 ;set window size
Graphics3D 640,320,0,3 ;set output resolution
