m_pDevice->CreateTexture(1024, 1024, 1, D3DUSAGE_DEPTHSTENCIL, D3DFMT_D24S8, D3DPOOL_DEFAULT, &m_pTexture, NULL);

I use upper code to create a depth stencil texture, at that time, the back buffer size is 800*600, depth stencil format is D3DFMT_D24S8. This code works very well on any NV cards(I tested much NV cards) but works bad on my ATI card. I dont know the result on other ATI cards becase I only have one ATI card(X1300 256MB) for test.

so, my question is : Why create depth stencil texture failed on ATI card but succeeded on NV card by the same code?

What does the function return, and what does the runtime output in the 'Output' pane during debugging? This might give you a hint to your problem.

[coollofty]

The function return is "invalid call", and the debugging message is: invalid format specialed for create texture

Have you checked the CAPS? Could be the ATI card just doesn't support the depth-stencil format.

Perhaps IDirect3DDevice9::CreateDepthStencilSurface is better suited for your needs :)
