  • Win XP low performance - performance drop

    Hi everyybode, I install a Win XP last week and I was badly surprised with performance drop against Win ME. Before I gor about 2600 points in default test in 3DMARK 2000 but now only 1800. Second point, AGP can allocate only 16Mb against 61Mb in ME. PLEASE HELP.
    And the last problem in games is independent refresh rate 60Hz and I can´t change it anyway. CIAO

    Oh I forgot, I´m using 5.86 drivers, P3 672 and 256Mb RAM

      System specs?
      Gigabyte P35-DS3L with a Q6600, 2GB Kingston HyperX (after *3* bad pairs of Crucial Ballistix 1066), Galaxy 8800GT 512MB, SB X-Fi, some drives, and a Dell 2005fpw. Running WinXP.

        60Hz in games is a "feature".

        Did you update all drivers and apply all XP patches?

          I using Via chipset 693 and the newest hyperion 4.45 drivers. I have a Sisoft sandra but it doesn´t work with Xp properly(no video) info. So I can´t you get specs now.

            The AGP allocation is a "feature" in Windows 2000, might be the same in XP. So I don't think there's much you can do much about it. In fact, the whole "problem" as you're seeing it might also be because of the differences in the AGP implementation between the operating systems. If your games are running as good as they used to, there's no need to worry about some 3DMark score.

            The refresh rates can be set either in PowerDesk (by setting custom refresh rates for resolutions, you have to go the resolutions through 1 by 1 though) or by using some refresh-forcing software like RefreshLock.

            Have you got any shared IRQ's? That could cause some slowdown (unless all devices are at IRQ9/IRQ11, which is normal if you're using ACPI).

            BTW Which Matrox card are we talking about (G400? G450? G550? 16MB? 32 MB? Single or DualHead?)

              weird thing is that nVidia cards with DMA AGP implementation (Matrox uses DiME), will address as much AGP aperture size as you specify in the BIOS, with the newer driver sets (i.e. not older than about a year).

                my card is G550 and the games are slower than they used to be. Il2 sturmovik in OpenGL is not OK (graphic problems). My card is G550.I think IRQ is 11.
