Turning off GL Extentions

I wondered if anyone knew the console command in quake 3 powered games to turn off the GL Extentions.

Because you cannot turn them off in Medal Of Honour (Q3 engine) from the menu!

Is there a console command, if not, is there another way of turning them off?


Just curious. Why would you want to turn of the extensions? Isn’t there a switch in the game to do so (In Q3 there is an option in the setup menu)?
