Prob's starting Unreal Tournament

Try this to get your game started.

Download this file
Extract the file named OpenGLDrv.dll from the zip archive and place it in
..\UnrealTournament\System\
Overwrite the file of the same name that is already there.

Now you have installed the latest version of the enhanced OpenGL render for UT, go click on START on the bottom right of your desktop
Then go on Programs
After that click on Unreal Tournament
There click on Unreal Tournament (Safe mode)

Select "Change your 3D video device"
Click on the option "Select All devices" (it is not the default selection)
Select OpenGL Support and click Next etc... until Unreal Tournament start.

That should work.

Notice : you must be patched up to date (patch 436).

If you want more help, attach to your next post your UnrealTournament.ini (it's a text file) to your post and we will give a look to see if there is something faulty there.
And attach the unrealtournament.log (it's a text file) too, this should be very usefull to locate the problem.

Of course, if you are using illegal version of UT or if you are not patched in 436 there is no solution.

Strange that your UnrealTournament.log is empty.

To start change that line

LocalMap=CityIntro.unr

Click to expand...

into

LocalMap=UT-Logo-Map.unr

Click to expand...

this will speed up the UT startup

Then change that line

WindowedViewportX=512
WindowedViewportY=384
WindowedColorBits=16

Click to expand...

by

WindowedViewportX=640
WindowedViewportY=480
WindowedColorBits=16

Click to expand...

in the case UT want to load in windowed mode and that 512/384 is unsupported by your monitor/radeon
Then change this

FullscreenViewportX=640
FullscreenViewportY=480
FullscreenColorBits=16

Click to expand...

into this

FullscreenViewportX=800
FullscreenViewportY=600
FullscreenColorBits=16

Click to expand...

in the case your Radeon do not like 640*480 in fullscreen when using OpenGL

Then find this

[OpenGLDrv.OpenGLRenderDevice]
Translucency=True
VolumetricLighting=False
ShinySurfaces=True
Coronas=True
HighDetailActors=True
DetailTextures=True

Click to expand...

Replace those few lines by the following

[OpenGLDrv.OpenGLRenderDevice]
Translucency=True
VolumetricLighting=False
ShinySurfaces=True
Coronas=False
HighDetailActors=True
DetailTextures=True
TruFormMinVertices=0

Click to expand...

Notice the line

RefreshRate=0

Click to expand...

Change it to your refresh rate, as some people reported problems with 0 (normally it is supposed to detect your refresh rate automatically)
So if your monitor refresh rate is 85hz , just replace it by
RefreshRate=85

This should get you started (but be sure to be in version 436 or the enhanced OpenGL should have lot of difficulties to work)

In the case it always does not work, restart Safe mode and change to Direct3D (with all the previous modifications)

A question to finish , have you ever succeeded to play UT in Direct3D or OpenGL before ?
If yes, it could be a ATI driver that you have installed recently that is not UT friendly.
I assume of course your system has no virus/spyware etc... as i assume you have checked your system first before asking for help here.

In that case, it is useless to post an empty unrealtournament.log, there is nothing you can find in it to locate the source of your problem.

And you don't said if something changed after the modifications i suggested.

When you have uninstalled UT , have you got rid of the UnrealTournament folder too ?
Because this folder is not deleted during the uninstall process.
And if there is a faulty file, it will be there even if you reinstall the game.

At this point, you can try to uninstall UT, delete the UnrealTournament folder , then reinstall and patch to 436 just after that.
And see if UT works like this before trying more things.
