WoW on Linux

Several months ago I switched to Ubuntu as my primary OS. The main reason I continued to use Windows at all was World of Warcraft. After much trial and error I have World of Warcraft running at a very acceptable performance rate on my system. Well enough to delete my Windows partition entirely from my hard drive. I recently posted on /r/wow on Reddit about playing World of Warcraft. Quite a few questions were asked. I will cover some of the more common ones in greater detail.

• Will my old AddOns work?
  Short Answer: Yes.
  
  Long Answer: Yes. Wine runs World of Warcraft. Essentially AddOns add to the existing functionality of WoW. WoW AddOns cannot communicate outside of World of Warcraft. Therefore there should be no compatibility issues. The people over at WoWMatrix even have a native Linux client available. The WoWMatrix client makes updating AddOns as easy as clicking a button. Windows based WoW AddOn clients such as the Curse Client may also work using Wine, I have not tested though.

• Should I install WoW using CD, Installer, or Copy?
  If you have an existing WoW install on another partition, hard drive, or computer I would highly recommend directly copying the entire WoW folder over to your Linux partition. It is by far the fastest way. My second recommendation would be to use the WoW universal installer. The universal installer downloaded the entire game over the internet, eliminating the need for CDs. Depending on your internet connection speed, expect this to take at least several hours. Installing from the CDs should be a final resort. WoW installation over CDs can sometimes be very tricky and time consuming. The extra effort is not worth the extra time the universal installer will take. If you must go this route, and if you have issues with installing from the disks, try copying all data from each disk to one folder on your hard drive and run the installer from that folder. This is a work around for a common problem while installing via the CD.

• Hardware
  Hardware selection is very important, especially while using Linux to play WoW. Generally speaking 4GB of RAM and a dual core processor is a minimum. The graphics card is especially important. Currently a NVidia card will perform better then a comparable ATI card under Linux. This is because ATIs Linux drivers just aren't that good. There has certainly been improvements in the past year, though they have not quite caught up to NVidias Linux drivers quite yet. Do not be scared away if you have an ATI card though. I personally use an ATI Radeon 4870 1GB card. I play on ultra settings and I get 60+FPS while questing/doing dailies. ~40FPS doing BGs other then WG. The biggest downfall of this card is when raiding in >15 groups. Often in large groups I will get between 20-30FPS, sometimes lower. I usually lower my Video settings to medium while doing these activities. Often it is not noticeable, in such a large group it is difficult to determine FPS.

  My Hardware: 4GB RAM, AMD Phenom II x4 940(4 x 3.0GHz), ATI Radeon 4870.

  Something else worth mentioning is the lack of a hardware cursor with OpenGL. This means that the mouse will become sluggish if FPS drop below 30FPS. There is a patch for Wine available that will use the systems hardware cursor. Some functionality is lost though, such as hovering over tooltips. My primary character is a Warlock. I have most my keys bound, making the mouse issue trivial at best. The mouse issue should not be an issue for anyone besides healers or anyone who is a clicker.

• Stablilty
  Stability is the same as would be expected using Windows. I rarely ever have WoW/Wine freeze while playing. If you have issues, I would recommend looking for other possibilities such as bad ram, or AddOns conflicting. I would also recommend running a repair on WoW. I have not run into a Wine specific bug for several months.

• Tips?
  I have a few tips that hopefully will ease the tension of switching from Windows to Linux for World of Warcraft. Most importantly, make sure you have the latest GPU driver available for your card. Drivers are always improving, often fixing issues, and increasing performance. Also make sure all desktop effects are off while running WoW. If you are using Ubuntu/Gnome - Goto: System > Preferences > Appearance ---> Click on Visual Effects, and select None to turn off all effects. This is important, more times then not, WoW/Wine will not run at all with any desktop effects enabled, if it does - expect less then desirable performance.

  I would also suggest using another desktop manager other then GNOME or KDE. Both of these are heavy on resources, when playing WoW every resource is vital. My personal recommendation would either be to use just a Window Manager (OpenBox, FluxBox, etc) or a lightweight desktop environment such as XFCE.
  

The journey to World of Warcraft on Linux will most likely be difficult in the beginning. Don't expect everything to work flawlessly the first time around. Don't give up, the effort will be well worth it. I hope the answered questions above will help to determine if WoW/Linux is right for your system. There are already many great installation guides floating around the internet, I would recommend the installation guide on WoWWiki.
