Yes, that's true as far as I can tell. Texture data is, however, saved in AGP memory and pointed to by the command stream. This involves allocating a piece of mappable AGP memory from the drm AGP memory allocator, putting the data in it and send pointers over the command stream. /Thomas >> >> Regards >> /Thomas >> >> >> >> >> >> >> >>>> >>>> /Thomas >>>> >>>> >>>> >>>> >>>> >>>> >>>> >>>> >>>>> >>>>> ------------------------------------------------------- >>>>> SF email is sponsored by - The IT Product Guide >>>>> Read honest & candid reviews on hundreds of IT Products from real >>>>> users. >>>>> Discover which products truly live up to the hype.
