What works

Single player, multiplayer, beautiful graphics. When looking simply in the wall framerate is ~60.

What does not

On many levels like Deck and with detailed scenery fps drops to 15, making fast paced shooter unplayable. Changing graphic preferences, resolution won't help, game hogs on cpu a lot. Seems like software\UT3 itself problem, cuz many windows native users reported same issue on good hardware. Meanwhile none of console players reported same problem.

There is no known solution, in 2017, (yet) to this problem.

for me, on my hardware, when i enable "stat engine \ stat ld \ stat fps" in game console, stable fps ~60, and static mesh tris < 200 000. But when I look across map, like on Deck bridges, static mesh tris goes from > 200 000 to 800 000, framerate changes to 18 and movement become unplayable.

I tried in the following environments to resolve: kernel 4.10, 3.16; wine 2.8, 1.8, nvidia drivers 375.39, 340.32. I spent many days trying to different options, configurations, "-onethread", various UTEngine.ini params to get it fixed. Nothings helps.

EXCEPT: compiling wine 1.7 from source with -o3 -m native, etc optimizations and applying Stefan patch from so, after that, framerate still drops but to much lesser extent, to 25-30, so his patch really helps. Also disabling "delay cpu for 1 frame" in game preferences helps to improve framerate.


What was not tested

installation\re-installation. (I just copied game folders across hard drive)

HowTo / Notes

Sugestions about Test result submit

This notes was updated: August, 03 - 2013

First of all, thank you for spending some time to help Wine to get better,

I would like to make some suggestions for you to make your tests results more relevant to other users of Wine:
  • Detail your PC specifications at the Extra Coments section (e.g. your video card, processor, and system memory).
  • It's also important to specify your video card driver version into Extra Comments section.
  • Specify if you installed the game into a fresh Wineprefix (or not), and what programs you actually installed.
  • Detail what version of the Windows emulation you use in your Wineprefix (e.g. Windows XP, 7, etc).
  • Add a comment about what is not working.
  • Specify if you made any changes to your game e.g. like a games "Mod", an patch (official or unofficial) or details of any modification you made to the stock configuration files from the game.
  • Please, don't send tests results with "Everything is working" or "Everything isn't working".

These are recommendations to make tests result more uniform and targeted to include common information that will be useful to other users of Wine.

How-To Install the game.

You need:

  • A recent version of wine, it's recomended the last release.
  • A video card with 3D Acceleration suport on your unix.
  • The 3D driver installed for that card.
  • It's not necessary a clean prefix, but it's recomended.
  • Steam installed and running, to do that, follow the steps on Steam page.


Just install your game like other normal game installed on Steam, it's not necessary any patch or program. For more detail how to boost your games see the section Tips below.


For make Unreal Tournament 3 run better and without any problem, install Visual C Runtime libraries, to do that, download here and here and install-it.

After installing,to override wine vcrun to the native one, create a file called vcrun.reg and put the following content:


Then run the follow command:

env WINEDEBUG="fixme-all" WINEPREFIX="(your-prefix)" wine regedit ./vcrun.reg

You can also install Visual C runtime libraries using winetricks, by typing:

env WINEPREFIX="(your-prefix)" ./winetricks vcrun2005 vcrun2008

To also make sure that everything will work fine, install the tahoma.ttf, arial.ttf, verdana.ttf and lucida.ttf fonts on your prefix. You can do-it manually or using winetricks with the follow command:

env WINEPREFIX="(your-prefix)" ./winetricks corefonts
For steam related problems, please visit the Steam Official Release page.

Unreal Tournament crash on start-up, don't open.

This bug normally happens because of the Visual C Runtime, see the Tips section for more information.

Unreal Tournament 3 Laggy, slow:

This happens in alot of games if you dont set the size of RAM that you VideoCard has, use this registry key to set:


Change the 768 to the real ammount of RAM in MB that your VideoCard has.

 Game closes shortly after open.

This is a common Steam Overlay problem, to solve, open your winecfg and override the library gameoverlayrenderer to Disabled.

Old Problems.

Note: These problems don't affect the newest versions of wine, it's only here for precaution, if you have any of these bug's maybe you should upgrade your wine version.

Mouse stuck into the edges of screen, cant turn 360ยบ

This happens because the Mouse Input of wine is not so good until now, you can solve adding this patch to registry:


The Mouse will not work into the menu, you gonna have to use the keyboard to walk into the Unreal menus.

Mouse is showing in the screen while playing (Only steam version).

This bug only happens with the Steam version, all the games into steam has this problem with old versions of wine/steam.

See more at bug #27779.

Mouse randomly jumps around menu or in game.

This is caused by implementation of mouse input in old versions of wine, to solve-it, you need to run the game in Windowed mode or into a Virtual Desktop.

UT3 Logo hangs indefinitely using 100% of cpu.

You can solve this problem by using the options -nomoviestartup and -onethread in the game executable. Newest version of wine don't have this bug.
