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

• Detail your PC specs in 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 - be specific not vague!!
• Specify if you made any changes to your game e.g. like a games "Mod", an .exe patch or details of any modification you made to the stock configuration files from the game.
  

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

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.
  

Installing:

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.

Tips:

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, create a file called vcrun.reg and put the following content:

Then run the follow command:

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

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

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

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

[HKEY_CURRENT_USER\Software\Wine\Direct3D]
"VideoMemorySize"="768"

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

This bug is related to Steam in-game overlay, to solve, add a entry on winecfg libaries section called gameoverlayrenderer and set to disabled.

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.

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

[HKEY_CURRENT_USER\Software\Wine\DirectInput]
"MouseWarpOverride"="force"

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.
