MTW perf options question...

[Achilleslastand]

Under the performance options in MTW there is one called AGP memory. Does anyone know exactly what this is for?
Maybe its for AGP video cards only and i guess should the slider be all the way to the right?

I think it's used for the AGP video cards of old. My guess is that it is used to control the AGP aperture for texture storage.

Mine is set all the way to the right, but I don't think it means anything if you are on PCI Express.
