Non power of 2 texture and MipMap on G45/G43 chipset

[tmaresville]

Intel G45/G43 Express Chipset

Driver Date: 09/21/2010

Driver Version: 6.14.5303

OS: Windows XP Pro 32bit SP3

In my application I try toCreatea texture with a non power of two size with multiple level of Mipmap, Forexample:

IDirect3DTexture9* pTex = NULL;

hr = g_pd3dDevice->CreateTexture(200,240, 7,0,D3DFMT_DXT5,D3DPOOL_MANAGED,&pTex,NULL);

it fail to create the texture because of anD3DERR_INVALIDCALL on the Intel G45/G43 graphic chipset.

if I put theMipLevelsto 1, or if I use power of two texture, it work fine, but I can't make it work using both mipmap and non power of two textures.

all the documentation I found say that it should works.

the caps :

D3DPTEXTURECAPS_POW2 ==> NO

D3DPTEXTURECAPS_NONPOW2CONDITIONAL ==>NO

that is supposed to confirm that it should work.

do you have any idea why itdoesn'twork ? and what is the best way to solve myproblem?

thx.

just out of curiosity, does this call succeed with the value of 3 for the mip-map chain depth?

did you try to auto-generate the mip-maps, to see if that works? and see what the depth is of the auto-created chain?

perhaps its also worth trying this without using managed textures, just to see if that is part of the equation.
