Probably not a problem with the settings in Archicad.
But have you updated the drivers for your video card?
OpenGL uses the video card so I would be guessing that is your weak point.
If updating drivers doesn't work then you might want to look at updating the card or if you can the whole machine - it does sound a little old.
