    Win2K AGP limitation ?

    This is not directly coding related ... but maybe anyone has a solution.
    It seems that the AGP texture memory in Win2K is limited to 32mb.
    I tested this with a G400, a TNT2, a GeForce1 and a RadeON. Same result.
    Even if i set the aperture to 256Mb, i never get more than 32 MB of agp mem. The NVidia AGP utility, Powerstrip and Sandra 2001 all report 32 MB.
    BTW, i have 320 MB of system memory.
    And in Windows ME, i have 128 MB of AGP memory with the same configuration.
    Does someone experience the same problem ?
    Some comments/solutions ?

    Yes, Microsoft and Intel have managed to screw up AGP pretty thoroughly.

    AGP memory isn't in any way guaranteed to be larger than video memory. Some day you might have a 256MB video card but only 10MB of AGP memory.

    (Yes, some systems have far less than 32MB of AGP memory.)

    Yeah ! Another great feature !

    Is this chipset/motherboards related ?
    Or can we hope to have this fixed in the next service pack ?
