DirectX 8.1 on nVidia Quadro FX 1300 problem!

Hi All,

we designed a 3D medical project for CT and MR to draw a scene using
three different pixel shaders. It works on any video cards(Such as
nVidia, Matrox, ATI, etc.) on 32bit machine properly and under any
OSs. But it looks weird on nVidia Quadro FX 1300 on Dell Workstation
370( 64 bits machine).

The brief description about drawing is like:

- Clear 3D device
- BeginScene
- Select pixel shader A; Draw something
- Select pixel shader B; Draw something
- Select pixel shader C; Draw something
- EndScene
- Present

The weird performance looks like current scene is previous scene,
sometimes two scenes are mixed up.

What causes the problem? Does PCI Express card cause the problem? Does
new feature of new so-called generation nVidia card cause the problem?

When I draw three different parts of one texture on three different
viewports using three DrawPrimitive, it appears same part of the
texture on the screen. But when I draw the three different parts of
one texture on same viewport using only one DrawPrimitive, it works
properly.

Might want to upgrade to DX9.0

Thank your suggestion first. Do any 3D games developed in DX8 update
to DX9? What a great job to do! I don't know what kind architecture
beneath the nVidia so-called new generation video card. Does it handle
special message for itsself? or update and present scene when change
viewport or matrices? or other wired stuff?

When you install the game it will usually update it to the required DX
level. I would try to find 9.0b if you could. 9.0c seems to have problems
for a few people.
