Here is my situation. I just bought and installed an ATI 9600 Pro 256 MB video card. I had a 64 MB one in my Dell 8250 prior to my installation. After the installation, i see absolutely no difference in FS9. Graphically and flyability is no different. I still studder and hiccup down the runway. I have 256mb of RDram, and have 512 more in the mail as we speak. Will that resolve the problem? I cant figure it out. I thought a new video card would drastically improve FS9.....but i was wrong! What am I doing wrong? Thanks

You could try reformating, that is what I did.

At the very least re-install windows. Windows is all set to run on your old card at the moment, all kinds of little stuff it will change with a reinstall.

Before you go as far as formatting and reinstalling Windows try cleaning out all traces of any previous display adaptor and it's drivers.Go to the device manager click on Display adaptors ,see what it says- it may still be listing your old card as well as your new one.Whatever it says, remove(delete) all listed adaptors as well as the drivers(there is an option to remove the drivers in the "properties" screen for each adaptor )When you have done this it should show only something like "standard AGP display adaptor"(not sure of the exact wording.)Check to see that all, traces of any graphics Card drivers have gone ,if not, remove manually.Shut Down and Restart.The system should detect your new card on start up("new hardware found", install the drivers/applications that came with it and see how things are then. If still no improvement then ,yes maybe you should do a clean Windows install etcDave
