I have a Dell Dimension 2400, 1GB RAM, 2.8 Ghz P4, X1300 PCI (not express) card. My games run great...(Oblivion, LOTRO, etc.) except for one thing...my in game movies run very choppy. Is this an issue with the driver or is it something else? It does it with the drivers that came on the disk and the latest drivers as well. Does anyone have any suggestions on what I can do to fix this? Any help is appreciated!
