I need some help with benchmarking and with HW compatibility/driver issues testing.
Its a demo that writes out the framerate and does some soft shadow stuff.
You can find the zip file of the soft shadow demo at
http://www.tooltech-software.com/downloads/gizmo3d/binaries/win32/shadowdemo.zip
Thanx in advance…
Framerate ranges from ~42 to ~52 fps with the default windowsize.
System is an Athlon XP2600+ (333FSB) on NForce2 + Hercules Radeon9700 (no OC) and latest Catalyst 3.10 (CoD Hotfix), with activated 4xAA and 16xAF.
Edit : Just took a closer look and the shadows don’t look as they shoud look (at least seems to be so). If needed, I can post a screenshot.

Any image errors. Do you see the shadows ok ?
Thanx anyway !
On a gf3, PIV 2.2gHz:

repeated each frame…
Beside that, it seems to work ok, with some “soften” shadows - several shadow volumes(?).
35 < FPS < 50
Please note that the text is nearly unreadable, due to the poorly choosen color
EDIT: I do have the “big shadow that should not be there” too. It looks like the yellow quad’s self shadow, IMO.

Yes. Please do post a screenshot or you can email it to gizmo3d_support[at]sts.saab.se

One can clearly see the shadows of the 2 objects, but there is another big shadow, which looks weird. I don´t know from which object that shadow is supposed to be. Could be the shadow of the shadow-receiver itself (which would be wrong).

Anyone knows whats wrong with this VP on a GF3 ?
gzGFXProgram theVertexBlendShader;
const gzString GZ_VP_VERTEXBLEND=

Here you go…both screenshots don’t look okay : http://www.delphigl.de/gizmo1.jpg http://www.delphigl.de/gizmo2.jpg
The second one also shows the big box shadow Jan mentioned.
GF4/Athlon 2.4 : 60-70 FPS
Shadows look like several shadow volumes.
Like others, one big shadow + “Gizmo3D Debug::Graphics Engine Error:1280” each frame

Do you get the graphics engine error as well ???
Ah, yes, i do get it (didn´t see it, the window was covered, sorry).
And some other errors at the start of the program: http://www.artifactgames.de/IMAGES/bla2.JPG

OK. I guess the GF family doesn’t understand my VP then. My Radeon 9800 doesn’t complain 
So all you guys with GF. Thanx and I might resturn soon… Thanx anyway…
my framerate min is about 278fps and max that i noticed was about 360fps or so…

But I guess you will get the graphics engine error as well.
Does your image look like my posted url above ?
no i do not get any errors at all…

But I’m on a Radeon 9700 (which isn’t that much different ) and still got no proper shadows. Have you tested it with the newes Pre-Cat 3.10?
Havent seen that use of ALIAS before. I thought they where there to ALIAS variables (TEMPs)
why dont you use the ATTRIB to get names on incomming values?
We have tested it on a Radeon 9800 with the latest drivers, no problems.
Just one question, are you using multiple shadow volumes to simulate an umbra/penumbra effect?
