Dawn Demo on 6800GT OC

[Kemo]

I upgraded from a beefy FX5950U which was quite a card but I wanted a next gen card w/o buying a new mobo/cpu. I know for a fact that the Dawn Demo was made for the FX series, esp the Ultra one for the 5900's. I remember the Ultra Dawn Demo ran pretty damn smooth on my 5950. Now when I try to play it on my 6800GT, it struggles like crazy. However, Doom 3, HL2, Far Cry, all butter, AND Nalu runs smoothly, even Luna, a demo for the 7's runs smoothly on my pc. Im using an OC AthlonXP-M @ 2.4Ghz 1GB ram nforce 2, the works. Forceware 81.89 Beta. Any suggestions would be great. thanks.

I think there is an open issue with the demo. The below info is from the 81.95s and is listed as an open issue. It's probably the same with the 81.89s. I found this in the driver thread, btw.

• GeForce 7 Series, GeForce 6800: The NVIDIA Dawn Ultra demo runs
slowly on AGP systems.

Kemo,
What the FPS you are getting with Nalu demo ?

[Kemo]

i get solid 17fps in nalu, but i found drivers that run Dawn smoothly, forceware 78.01. im gonna try a bunch of drivers.

I think I was getting a lot faster than 17 in the Nalu demo but I was at the default res.
