okay, after about 2 hours of trying to figure this out, i finally got it to work...

*Obviously, have doom III already installed to do this!!*
First off, you need to go ahead and run the setup for the 41.09 Drivers that will not work, but will give you the folder needed (usually, C:/Nvidia/2kXP/41.09)
Do not Restart after installation.
Uninstall your existing better drivers from the Device Manager.
Restart your Computer
DO NOT INSTALL THE DRIVERS WHEN IT ASKS YOU AFTER YOU LOG ON!
just press CANCEL.
Go back to Device Manager and go to Properties.
under the Driver tab, click UPDATE DRIVER
In that, click HAVE DISK, direct the file to the C:/Nvidia/2KXP/41.09, it will find the nvdspl4 or something. and hit OK
Scroll down on your list of choices to NV25<-crucial!!!
use that to install as your video card... (some weird things might happen to the screen, but it will come back after like 2 times and finish.
After Installation, Restart
Log back on, reset your screen resolution in Display Properties
Finally, load up Doom III and it should work!
Be Aware that it may take longer than usuall, becuase the NV25 driver is making your FX think it is a Ti4800, and for those of you who are risque may want to try installing the driver as something other than NV25 and see if that works, but do not hold me accountable if something goes wrong... lol

Well, I hope that Helps Anyone with a Geforce FX, and remember to install the new 56.57 drivers back when you're all done with playing or showing off the beta!!!

Have Fun and Enjoy!!!!!

Nice job SDC.

Thanks Man! it took alot to figure that darn thing out! LOL

I'm sure that Mike is going to love this.

Oh I know He will.... He was dying to figure out how to get it to work! lol!

...

Thanks for trying man!

I know we tried to get this to work last night but I had no luck. Hardware would fail everytime using that old driver.

I guess I will have to keep looking around until I can find something about using new G-Force cards on Doom3 beta

Awesome post though man!! Great Job!!
