Same here, I've tried different combinations of settings too. Using XP, AthlonXP, NV25, 30.30 drivers. Funny, I got other Cg demos to work, but not this one.

Also, speaking of Cg demos, can anyone get the furry donut demo to run? It doesn't seem to include an executable in the zip.

Tried to DL the demo, but the link is dead or something, maybe the ATi boys ARE the hackers
Anyone have a link?

I just ran it. Looks great. Be sure to uncheck 16bit color under miscellaneous.

Thanks wysiwyg, they changed the page since I saw it this afternoon. They had us going to the site of the company that made it, but it was dead...

OK, just DL'ed it, and ran it...locked up tighter than a frogs butt in water...

Everyone who ran it sucessfully, please state your driver version.

Or how about this! State your driver version, and say if it ran, or failed!

33.30 : Failed

EDIT: Nevermind...JamesDax's tip worked perfectly...uncheck 16bit...Thanks bud !

hehe, yeah it works...runs like crap with dynamic shadows (not total crap, but not over 30fps).
If I disable dynamic shadows it runs great except for the winter scene, probably because of more polygons for the bare trees...

Sounds cool, someone mind taking screenies? I still can't get it to work, no matter what settings, desktop res, or color depth I try. It either hardlocks at a black screen, or XP gives me that "SpeedTreeRTDemo.exe has encountered a problem and needs to close. We are sorry for the inconvenience." message.

With 32 bit I was getting about 25 fps
Using 30.30's with RT RC 11.1



By the way I was able to run it with 16 bit colors.
