How do I check if the video card can use D3DCREATE_HARDWARE_VERTEXPROCESSING in IDirect3D8::CreateDevice()? I couldn''t find it in the D3DCAPS8 structure. If I specify that flag and hardware processing is unavailable, will the device automatically be created with software vertex processing or will the call fail? If the call fails: What would happen if I make the call with mixed-mode processing? Would that also fail if hardware processing is unavailable?

Here''s an answer, it''s in Visual Basic but I''m sure you''ll get the idea.

Set D3DDevice = D3D.CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_HARDWARE_VERTEXPROCESSING, D3DPP)

If D3DDevice Is Nothing Then Set D3DDevice = D3D.CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, D3DPP)

This code will see if hardware vertex processing can be used, if not, try software. I hope that helps
