Hi. everyone.

    Program is crashes when making it again after the very large
vertex buffer etc. are made on 64bit Windows Vista( ex. 60MB vertex
buffer etc ). It doesn't crash on 32 bit Windows Vista. Why ?
Is this driver's bug ?

(1) CreateBuffer  etc...   <-- 60MB Vertex buffer
(2) It releases it at once.
     ex)    g_pVertexBuffer->Release();
              g_pVertexLayout->Release();
              g_pRenderTargetView->Release();
                   etc...
(3) It creates it again at once.
     CreateBuffer  etc...   <-- 60MB Vertex buffer
           Crash....

64bit Windows Vista.
GeForce8800GTS 512MB.
ForceWare Release 169 WHQL Version: 169.21

32bit Windows Vista.
GeForce9600GT.
ForceWare Release 174 WHQL Version: 174.16

DirectX SDK Version 2008.03

It could be an intentional limit (while it seems rather odd to place that on the 64 bit version, though). Might be worth to check the MaxPrimitiveCount device caps. Also, how does it crash: e.g. do you ignore the HRESULT of the create vertex buffer call or does the call cause the problem?

Edit: Just noticed this is D3D10...

Edit 2: After re-reading the question it sounds like this is indeed a driver bug... As unrelated reference here are the Minimum D3D10 Resource Limits.

The return value of the method cannot be acquired.
It is not possible to capture it even with 'try-ctach'
The method including CreateBuffer crashes.

Because I did not know 'Minimum D3D10 Resource Limits.', it reads.

jwatte:

If it works on REF, and not on the NVIDIA driver, then it is an NVIDIA driver bug.

Oh, how could I forget about REF?

Bug was fixed by a new 175.16 driver.

Thank you all !
