Hi,
enumerating Z-Buffer formats causes problems on many cards, so it was on my Elsa Victory Erazor. I had to set the format on my own and it worked on every card I checked it out. Simply set the bitdepth and pixelformat and things like that on your own and it should work.

If the DirectX-samples work, then simply copy the code from that samples and it should work without any problems.

Are there any bit depth restrictions for the zbuffer when you are using HAL?

I'm trying to get a simple d3d-im program running, but when i create the z-buffer (w/ CreateSurface() ), it returns with DDERR_INVALIDPARAMS, i'm using the exact code from the D3DIM tutorial that comes with DX6, I don't really know whats going on.

heres the code that i'm using:

ddsd.dwSize = sizeof( DDSURFACEDESC2 );
ddsd.dwFlags = DDSD_CAPS | DDSD_WIDTH | DDSD_HEIGHT | DDSD_PIXELFORMAT;
ddsd.ddsCaps.dwCaps = DDSCAPS_ZBUFFER;
ddsd.dwWidth = m_iXSize;
ddsd.dwHeight = m_iYSize;

memcpy( &ddsd.ddpfPixelFormat, &ddpfZBuffer, sizeof( DDPIXELFORMAT ) );

ddsd.ddsCaps.dwCaps |= DDSCAPS_VIDEOMEMORY;
DDSCAPS_SYSTEMMEMORY;

hr = lpDD4->CreateSurface( &ddsd, &m_lpZBuffer, NULL );

if( FAILED( hr ) )
return DDErrToGFXErr( hr );

as you can see i kept everything the same except:
- i already know what size it should be
- i automatically use HAL

I have no idea what i'm doing wrong
