I came across with an old article posted by NVidia. it can be compiled but nothing shown. IS that cause by hardware problem? Here are my PC info: Operating System : Windows XP Professional Service Pack 2 (build 2600) Processor : 1.80 gigahertz AMD Athlon 64 Drives Display : VIA/S3G UniChrome Pro IGP [Display adapter]

Since it is an nvidia demo it may have something to do with your card not being an nVidia.


I'm unable to run ati demos on my geforce 6600, so I think that this could be the cause...

Since I wrote that demo for NVIDIA, let me answer your question:
Your video card basically lacks support for vertex and fragment (pixel) shaders which happen to be required for the demo to run.
Can you please post the content of the log file here? Thanks =-)

is not really a graphics card (u need something recent from either ati/nvidia or a recent intel onboard)

minimum "NVIDIA nForce 500 Series" or "GeForce MX" will do?

No, nForce's are motherboards (with integrated graphics perhaps) and the Geforce MX's don't have any pixel processing ability in hardware. Get a Geforce 6/7. If you want it really cheap I think you should get a Geforce 7300 (but I don't own one so I can't give you a review). If you are OK with a little more pricey, Geforce 6600GT/6800/7600GT I would say.

I discovered a few weird things in that demo.
I while back I ran it and it was fine. Rendered the grass, skies, everything.
A week or so ago I tried running it again and it gave me a compilation error. I was like "huh?". I unzipped the project and ran the app again only to find the same errors witht the grass shader code. I was confused. So I commented out everything the compiler was complaining about and ended up having no rendering of grass but I still had a low fps asif the card was rendering it.
Another thing thats weird (and its a good one, but I think I can explain why) is that the scene renders faster if you enable Anti-Aliasing. Weird, but then I remembered an article where people talked about the optimizations thats with those rendering effects that helps the renderer draw faster.

Anyway, just thoaght I added my 2c.
Nice demo JavaCoolDude! Oh, just a personal question... didn't you get tired with working with that XML code the whole time? [wink]
