    Hi,

    I'm the happy owner of a pretty workstation based upon a DEC AlphaPC
    164LX motherboard. I recently upgraded my aging DEC PowerStorm 4D60T to
    a Compaq PowerStorm 300 (PCI flavour, of course). With Tru64 V5.1, I'm
    getting catastrophic OpenGL performances (e.g. SPECviewperf 6.1.1 ended
    up with scores between 0.588 for the Light test and 4.697 for the AWadvs
    tests) where I was getting scores between 1.508 and 14.093 with my old
    DEC PowerStorm 4D60T. But the most crazy thing is that Windows 2000
    Professional RC2 (a not finalized OS) with the Windows NT Workstation
    4.0 PowerStorm 300 drivers (an unsupported OS/driver combo) gives me
    scores similar to my DEC PowerStorm 4D60T (1.447 for the Light test and
    17.12 for the AWadvs test)!

    What am I missing here? Of course, I did install the appropriate Open3D
    drivers...

    Thanks.
