Sorry, should have mentioned that. It's AGP 128mb cause I don't have a PCI express MB
Also did some further testing today on my existing drivers, and with Mipmapping models I take a fairly strong FPS hit, but it keeps airbases and such from rolling/shimmering so bad, but the FPS hit is too much for me to leave it enabled.
Additionally, the ansiotropic filtering at 4x on this card makes the graphics look much cleaner, especially at a distance, but even with mipmapping terrain enabled the shimmering is evident.
So I reverted back to having anisio application controlled in my graphix card setup, and use terrain mipmapping enabled, object mipmapping disabled; and I get very nice framerates with decent graphics quality.
Bummer though, I like what Ansio does for the image when flying, but alas the terrain rolling/shimmering issue is unacceptable personally.
