    Unreal tournament 3 Hitches.

    I am experiencing hitches due to framerate fluctuation while in sli mode. I feel I have decent enough equipment, but nevertheless I am not able to turn without hitches in mouse movement.

    My system is:
    Maxtor DiamondMax HDD
    XP Professional 64Bit Dual boot withVista 64-Bit Ultimate
    ASUS M2N-SLI Deluxe MOBO
    AMD Athlon 64 X2 6000+ CPU
    PC Power & Cooling Silencer PSU
    CORSAIR XMS2 4GB MEM
    2x evga 8800gt ssc GPU

    With that out of the way, I have a 5v fan blowing on my 2 graphics cards so they maintain 55-70°c, and my cpu is watercooled and maintains 32-45°c.

    I have all of my drivers as current, have not done any firmware, or bios updates. My hard drive has been defragmented, and I keep it all this way.

    I Currently run Unreal Tournament 3 in 800x600 with 2 on details. Have vsync disabled. Have a CRT monitor that has 85hz refresh rate.

    My current forceware drivers are 169.09

    I have toyed with Minimum and maximumdesiredrefreshrate with no luck.

    I am stumped. Anyone have similar equipment with the same problems so we can discuss a possible solution?

    After all of this, I am still unable to move my mouse in game up down and around without seeing the movement studder.

      Well. I have just uninstalled all of my nvidia drivers - chipset, display, everything. Got to the point where I had to even reactivate windows. I acually had to call them.. But after I finished reloading my drivers, I started up the game, reset my resolution to what my monitor specified, and boom, no studders.

      But after awhile of having fun, I realized I never enabled SLI. So just now, I enable it, and lo, and behold - hitches and studdering. So. Um. Did I misunderstand some of the things saying this game would be supporting SLI, or did I just buy an extra vid card just so i could have it hooked up, but not use it.

      Glad I have this fixed, thank you, but will This game ever be supporting SLI without hitches? Also, anyone know when dx9.0L will be released? I hear it will be the dx10 for windows xp, which will enable AA support in ut3.

        See if that helps.

I would rather have that extra power put to use. So is nvidia drivers to blame for the "sli enabled" hitches? Is it epic, and Nvidia? Or does Unreal Tournament 3 even support an SLI system?

            Nvidia's latest release drivers (at least for XP) does have various UE3 and Unreal Tournament profiles (2003,2004, and 2007) but none use the UT3.exe (they are for the DemoGame.exe, Unreal.exe and UTGame.exe for Unreal Tournament 3), so at this time you have to manually setup a profile to enable SLI.

            If you do create a new profile for the UT3.exe, select "force alternate frame rendering 2" for your SLI setting, it seems to give the best performance, at least from what I can tell.

              Thats just my point, I can enable SLI, but no matter what settings I choose, I cannot get this machine to work without studders, or hitches with sli enabled. I would like to use this sli setup I have to get the lowest fluctuation in framerate - like for instance, I want to maintain 60-85 so:
              Mindesiredframerate=60
              Maxdesiredframerate=85

              so that My framerate will never go below 60 or above 85 and the only way I see me getting this is through sli which I cannot get to function properly. Unreal Tournament 3 supports SLI right?

                I was having a lot of hitches due to my CPU overclock being a little unstable. If you are overclocking try turning stuff back down to stock to see it it makes a diffrence.

                  No, all stock here - gpu's just run hot due to the fact that they are overclocked by the manufacturer. The "evga 8800gt ssc" runs at 70°c idle, and like 85-95 load.. So I have a fan pointed at them running 5v, so they run between 55-77 without too much noise. So it is a stable overclock due to the fact that I can run the game with just one card "sli disabled" without much of a studder. But I am trying to get SLI to work here so I can get the most out of my system.

                  I am currently giving NVIDIA a chance at the troubleshooting seat by running a 20minute tune on my pci-e using Ntune (the next-gen coolbits) within the nvidia control panel. No cpu, no memory, just the pci-e interface with sli enabled. I have run it disabled without having enabled sli without one crash, or hitch, but now that I am letting it test the interface under sli mode, I have to babysit. I know they say crash's are expected, but once you get a reboot, you have to answer a few prompts, and say a few ok's, then select "tune system" again to enable it to continue. Had a few VB C+++ runtime errors also if this makes any difference. And have sent many error reports to microsoft. And yes, since this is windows, I keep "Notify me, but do not download or install" box ticked in "Automatic updates" due to the fact I cannot visit windowsupdate and get updates for some reason.

                  Also,. My mobo has pcie-1.0 interface, and the new 8800gt's are backwards compatible with the upcoming 2.0 interface. I would buy another motherboard if one was available, but they are not being produced for a reasonable $$ yet I guess since I do not see any listed by any of the stores I shop. So, guess I will continue my babysitting ****.

                  I will keep you guys updated, and wanted to thank you all for your comments.
                  Keep them coming!

                      You made me hope for nothing... =(

                      "We managed to confirm the existence of DirectX 9.0L but it won't be a DirectX 10 for Windows XP. It will be the other way around. It is a faster version of DirectX 9.0 that will run under Vista only.

                      DX9.0L is a special version of DirectX 9 for Vista only that allows DX9 games to run with Vista's new driver model. It's not possible to run D3D10 on XP without running in pure software emulation."

                        tweakguides listed a way to run a benchmark on any specific map to measure framerate, and here are the results...

                        An SLI setup should be working it better then this.

                          whatever dude.. DX10 is VISTA ONLY. And dx 9.0L will be the xp version of dx10. Why would they make a modified version of dx9 to run over dx10 which is preinstalled in vista. Also, I see that you quoted, where did you see that?
