How to use Open Gl driver in Unrel Tournament.

by |ZM|Mike

This is a tutorial about the way to use Open Gl driver on Unreal Tournament for those who have Geforce Video Cards (Geforce 2, 3, 4 MX or non MX). If  you have a ATI card check the info in the bottom of this page. With the folowing steps you will be able to use a great driver for this game that will raise your frames per second on the game.

BEFORE you do anything you MUST instal the lastest DETONATOR drivers from NVIDIA and the lastest DIRECT X from Microsoft. Get the Detonator drivers here. Then choose DOWNLOAD DRIVERS, choose your operating system, download and run it.

Direct X can be found here. Download and run it. JUST after his two steps, come back to this page and folow the next 9 steps.

1st - You must know how many frames you are geting now so you can compare them later when you complet instal the open gl driver. To see the frames per second you are geting now, run UT and start a Pratice Game. Then hit console key and type TIMEDEMO 1 and you will see some data on the right side of your monitor. Write down the fps you are geting now.

2nd - See what video driver you are using now. Watch the next pic to see how to find this.

3rd - Leave the game and open the Unreal Tournament folder. Then open the System folder. Now you must be at c:\unrealtournament\system and you can see there a file called opengl.dll. That file is a litle old and you must replace it by the new opengl.dll that you can get here and then replace it by the old one.

4th - On that folder (c:\unrealtournament\system) you must edit a file called Unrealtournament.ini and find a section called [OpenGLDrv.OpenGLRenderDevice]. You need to delete whatever is under this topic and replace it by these lines:
[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=1
HighDetailActors=1
MaxAnisotropy=0
AlwaysMipmap=0
UsePrecache=0
SupportsLazyTextures=0

Now save the file (as unrealtournament.ini) and close all windows.

5th- Its now time to change the video driver you are using and choose opengl. Run UT goto Options - Preferences - Video like you saw in Pic above and click change.

You will get a screen like the next pic. Then click on Show All devices, then choose OPEN GL Support and then Next. You are now on the game with opengl driver and if you start a pratice game you will problably get much more frames per second and you are getting a better game smoth. The problem is that the game is too dark and you cant change the brightness. We will fix it after. Use the TIMEDEMO 1 command to see the frames and then leave the game.

6th - If you want to be able to change the brightness on UT using open gl driver, you must get off the V-Sync. You will need a software called RIVA TUNNER that you can get here . After the download, unzip it to any place. Riva tunner does not need instalation. Open the folder and run the file as seeing on next pic.

7th - After a few seconds click ok on the information message as seeing above. You will get a screen like in the next pic. Click on the litle triangle and then click on open gl.

8th - Now you must put V-SYNC ALWAYS OFF. See next pic.

9th - Close everthing, restart and run UT. Now you must be using Open Gl driver, you are able to ajust the brightnest and you are geting more frames per second with this open gl driver. If you get lower perfomance or you dont like open gl you can put it all back as it was. Just go to OPTION - PREFERENCES - VIDEO and change the Driver to whatever you were using before. The other steps you gave wont make any diference, you are exacly as you were before. Any other question just mail me clicking here.

For ATI users.

The DLL file you need (step 3) is this one here.

The data for the ini file (step 4) is:

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

And course, dont get the Detonators drivers and skip the steps 6, 7 and 8.
