Mipmaps failed with Texture-Flag 256

I´ve tested this on various Computers with different G-Cards and drivers.
If you set flag 256 ( store in Vram), Mipmaps does not work.
LoadTexture "test.bmp",1+8 works correct
LoadTexture "test.bmp",1+8+256 works not correct

Any ideas? Is this Blitz or the drivers/G-cards?

From memory mip maps are not supported with texture flag 256.

This is one reason why flag 256 makes writing to the texturebuffer much faster: mipmaps don't have to be updated.

You can't have both.

try to use dds... they are stored in vram and you have the option to enable mipmap.

cheers, chi

Unfort. dds textures TextureBuffer is always zero.

Now i know something more about mipmaps and Vram.

Thanks folks :-)
