Kentie’s upgraded Deus Ex launcher is very helpful for troubleshooting and tweaking.
"When due process fails us, we really do live in a world of terror."
While time has certainly placed Deus Ex into the same rarified air as games like Planescape: Torment, time hasn't been good to Deus Ex on a more technical level. Even for its time, DX wasn't exactly known for its graphical beauty. While the Unreal Engine would later go on to produce some visually stunning games like Rune, the game's somewhat lacklustre graphics were apparent even at launch. Character models were blocky (and everyone practically looked the same), and the overall look of the game's world - where the colour palette seemed to veer between dirt brown and gun mental grey - paled in comparison to other popular games of the period, like Sacrifice, Giants: Citizen Kabuto, and Heavy Metal: FAKK2. Voice acting was of marginal quality at best.
In the end though, that ultimately wasn't the point, was it? We don't see movies like Hard Boiled for the plot, nor do we try to find pulse-pounding adrenaline-fuelled action in the pages of a Jane Austen novel (undead remixes thereof notwithstanding). DX's graphics simply weren't that great, but people playing it were simply too engrossed in the game's atmospheric levels and surprisingly thought-provoking plot and dialogue to even care.
After installing the game using the CrossOver installer or a CrossOver CrossTie, open your Deus Ex bottle in the Finder and navigate to:
drive_c/Program Files/GOG.com/Deus Ex GOTY
The game's critical files are stored in the System folder. Here, we'll be installing a graphical update, a small update patch (relating to an in-game issue involving an important character), and an improved game launcher.
- Enhanced OpenGL Renderer - One of the first things to do would be to install a more advanced OpenGL renderer for Deus Ex. Expand the .zip file and place it in Deus Ex's System folder, mentioned earlier. It'd be a good idea to back up the old renderer (OpenGLDrv.dll) before you overwrite it.
- The v2.0 Fan Patch - Next is a small fan patch intended to address some lingering bugs in the game. Again, these go in the System folder, and also again, pay close attention to the names of the files, and back up the original files that they will replace.
- Kentie's Enhanced Launcher - This needs the 2010 Visual C++ Runtime installed to work. It's not yet available in the CrossOver Software Installer, so download the linked file and after pointing the CrossOver Software Installer to the runtime installer, install it into your Deus Ex bottle. The launcher itself is a drop-in replacement for the deusex.exe file in your System folder, in additon to some others. Again, back up the original files before rewriting them.
Most other mods should work, for the most part; I've run 1.3 of Deus Ex Enhanced and Shifter with no adverse effects. With the right hardware, the high resolution texture mod (Deus Ex: New Vision) should work, but given the limited state of my hardware, I haven't tried.
OpenGL performance is good, especially with some of the graphical options turned down, but the game's DirectX renderer also works well in my recent experience (with widescreen resolutions supported); in past versions of CrossOver, only OpenGL worked. If you have sufficient hardware the enhanced DX9 renderer provided by the same page as the enhanced OpenGL renderer might yield some benefit, but you need to have tutorial for getting GOG games to run on Mac OS X, and a list of games he has personally tested to work on Mac OS X through CrossOver, Wineskin, and open source ports.
