Am I to understand correctly that if I have generated my mipmap levels in my LPDIRECT3DTEXTURE9 correctly, and I pass it into the SetTexture function, DirectX will automatically choose the optimal level to use?
If I'm wrong, could somebody explain it a little better?
Unless you've done work to stop it (changing mipmaplodbias, or maxmiplevel), then yes, it just automagically works.
hi,
as Namethat... (your name's too hard to rewrite ^^) said, it should work. Just check that you have :
d3dDevice->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_LINEAR);
because if the sampler for mipmap is set to D3DTEXF_NONE, mipmap will be disabled

No. D3DTEXF_POINT simply uses a single point for choosing mipmap level. D3DTEXF_LINEAR uses a sampled 2x2 area. To disable mipmapping use D3DTEXF_NONE when setting the D3DTEXTUREFILTERTYPE sampler state.
