# UT Troubleshooting FAQ

Got a question that isn't covered here? Add it to the list (at its appropriate place) and leave the answer out. Somebody else will fill it in.

When running UT in Windows XP, I get distorted sound. How do I solve it?

  To fix the crackly sound you sometimes get in Unreal Tournament, when loading in XP, open Advanced Preferences (type `preferences` from console). Change:

  - Audio → EffectsChannels to 8
  - Audio → Latency to 60.

  After that, restart the game. The problem is caused by Windows XP's harddisk prefetching algorithm, loading Unreal modules faster than the sound subsystem can initialize properly – hence it only occurs when the engine loads from system cache. This worked for me and many others. I've tried different values for Latency and EffectsChannels, the lowest trouble free latency value is 46 and you can keep the effects number to 16.

  In the `UnrealTournament.ini` file you should have a section that looks like this:

        [Galaxy.GalaxyAudioSubsystem]
        UseDirectSound=True
        UseFilter=True
        UseSurround=False
        UseStereo=True
        UseCDMusic=False
        UseDigitalMusic=False
        UseSpatial=False
        UseReverb=True
        Use3dHardware=True
        LowSoundQuality=False
        ReverseStereo=False
        Latency=46
        OutputRate=22050Hz
        EffectsChannels=16
        DopplerSpeed=9000.000000
        MusicVolume=160
        SoundVolume=224
        AmbientFactor=0.700000

Getting the best performance in UT, some tips (Thanks to 'Valheru')
  - If you have a motherboard with a VIA chipset, get the latest VIA drivers from [here]. The installation procedure is explained here as well.
  - For video card drivers, usually getting the latest version of them will give you the best performance.
  - Get UT patched to version 436 if you havn't already. Also, before you do that now would be a good time to install the second CD for the high res S3TC textures. If the install bitches at you for any reason, like it wants version 400 instead of 436, just copy the folders on the second CD directly to the root of your UT folder.
  - Download the OpenGL.dll [here]. Unzip it to your UnrealTournament/System folder, and overwrite the existing file that's already there. Replace the OpenGLDrv.OpenGLRenderDevice section in your UnrealTournament.ini file (located in the UnrealTournament/System folder) with this :

        [OpenGLDrv.OpenGLRenderDevice]
        RefreshRate=75
        DetailTextures=1
        UseTrilinear=1
        UseS3TC=1
        UseTNT=0
        LODBias=0
        UseMultiTexture=1
        UsePalette=1
        UseAlphaPalette=0
        Translucency=1
        VolumetricLighting=1
        ShinySurfaces=1
        Coronas=0
        HighDetailActors=1
        MaxAnisotropy=0
        AlwaysMipmap=0
        UsePrecache=0
        SupportsLazyTextures=0

  If you didn't install the second CD textures, disable the line UseS3TC textures by changing it to read : UseS3TC=0. Also, up the RefreshRate line to the max refresh rate your monitor can take at the res. you're running UT at. Don't forget to disable VSync, both in the Driver Options of the Detonator's (right click on the Desktop → preferences etc.) as well as in the UT options (in the menu once UT has started up type preferences in the system console).

  A few tips: Disable Coronas, they look like ass under OpenGL and blind you as well (note that coronas are already disabled in the configuration above). Disable that stupid screenflash stuff - everytime you get shot with the minigun you can't see shit. And don't forget to change the DeviceRenderer to OpenGL.

  S3Textures FIX: this if for when you log in to servers which don't have S3TC textures installed and players seem to be skating around instead of walking around and they freeze when you kill em.

  Download [this], copy it to your ut\textures-folder and run it. It should fix that particular problem.

Anonymous: When I play a map through unrealEd it crashes out if I use dodge to much, any suggestions plz

DJPaul: Paste the END part of your log on the ScratchPad, so we can see the error.

## Comments

Tarquin: Should we tell people to post questions here, or direct them to the Help Desk?

Sobiwan: If I have a question, it is related to the page I am on, so I would write it on the page. When it has been answered, it can be refactored into the page.
