The game runs fine with current versions of Wine and Proton. This section is just for some tips on configuration.

The game only allows setting 4:3 resolutions. For widescreen open ~/.steam/steam/steamapps/compatdata/6920/pfx/drive_c/users/steamuser/Documents/Deus Ex - Invisible War/user.ini, and adjust FullscreenViewportX and FullscreenViewportY. Note that the saved games are also in this directory, if you want to backup them.

With the default settings the HUD and the in-game menus usually stretch beyond the screen, and this makes e.g. dropping items impossible. To fix this open ~/.steam/steam/steamapps/common/Deus Ex Invisible War/System/Default.ini, find FOV__d and set it to 50.

Two issues remain. Enabling multisampling just multisamples the HUD, but not the game world. It has always been like this, I guess this is a bug in the game.

QuickSave/QuickLoad are hardcoded to F10/F12. In the above mentioned two configuration files you can map these actions to other keys, but that just creates additional mappings. It is impossible to unmap F12 from QuickLoad, which is also the default Screenshot key for Steam. The best solution is to set another Screenshot key in Steam.

There is a community-made high-resolution texture pack that vastly improves the look of the game. Here is a before-after comparison:



The texture pack installer used to be available on moddb, but it was removed at some point. The FilePlanet[www.fileplanet.com] location seems to be still working. If not, you should look for a file named like DX-IW_Texture_Pack.exe, which is 139251852 bytes, MD5 sum a2aedf24f920b66f793eaee99707908e, SHA1 sum a7e3e97889880fa62049403ca49c3edfce617b41.

It is a meta-installer that puts the real installer into the game's folder, and runs it. Normally it should run fine, but it has a small roadblock.

It contains a utility called ibd_patcher.exe for updating the game's configuration, which needs a Visual Basic 6 runtime called msvbvm60.dll, but the installer doesn't contain it, and Wine doesn't have it. No error is shown if it can't run this utility because of the missing dll, the game just keeps using the original textures. You should see a black window like this when this utility is running:



There are two ways of obtaining the missing dll:

• Use protontricks to install vb6run
  
• Download from dll-files[www.dll-files.com] and extract the dll into ~/.steam/steam/steamapps/compatdata/6920/pfx/drive_c/windows

If you run ibd_patcher.exe manually it looks like this:



You can selectively enable certain parts of the texture pack with it. This is a minimal example of running it in the game's Proton context:

This is a shortened version of the original guide, kept here for historical reasons only. 10 years ago the game had several issues with Wine. Neither Proton nor vanilla Wine has any of these issues anymore.

• Getting rid of an error message spam about unsupported texture wrap mode: use the environment variable WINEDEBUG=-all to suppress all warnings. This was a major performance fix on my computer back then.
  
• There was a well-known problem with 3D audio in DirectSound[bugs.winehq.org], and a native dsound.dll was needed. Wine 1.7.42 fixed this.
  
• The game crashed upon startup if the Steam overlay was enabled. Wine 1.7.42 fixed this.
  
• The game lose mouse pointer grab each time it had a mouse pointer (entering menu, opening inventory, each dialog sequence etc), and needed a click to grab the mouse pointer again. No longer an issue.
  
• Quicksave worked fine, but quickload crashed the game. The quicksave slot could be loaded from the menu. Now quickload works fine.
