World of Warcraft has had tremendous staying power since first arriving in 2004. The game has taken over the massively multiplayer online game market with more than 11 million monthly subscribers, and it has had two expansion packs. The newest installment, Wrath of the Lich King, gives you the entire continent of Northrend to continue questing for loot and glory. Much of World of Warcraft's charm comes from fantastic artwork that doesn't rely on technical muscle, but Wrath of the Lich King comes with a few graphical upgrades that can challenge systems if you choose to enable them. Modest PC systems will still be able to run the game without a problem, but players running near the game's minimum specifications should consider swapping in a better video card and more memory.
We tested Wrath of the Lich King using the flight path between Dalaran and Ebon Watch. We took the average of three runs using FRAPs and a 65-second run time. We ran a separate in-town Dalaran test for our CPU evaluation, where we ran around the city square for 65 seconds.
Settings
Even a game as old as World of Warcraft has a few settings you can tweak to improve performance. Keep an eye on draw distances and shadows to squeeze out a few more frames.
Video Cards
Modern GPUs won't have any problems running Wrath of the Lich King. We tested 20 cards from the past and present to help you decide how much is enough.
CPU
Newer CPUs improve performance for Wrath of the Lich King, but you can probably survive Northrend without a processor upgrade. We tested the game using our Core 2, Phenom, Athlon 64, and Pentium 4 processors.
Memory
We tested the game with 1GB, 2GB, and 3GB of RAM. Our minimum spec test machine with only 512MB of RAM ran World of Warcraft: Wrath of the Lich King smoothly after we lowered the graphics settings, but we recommend going up to at least 1GB.
Systems
The required system specifications for World of Warcraft: Wrath of the Lich King are amazingly low: Pentium 4 1.3GHz CPU, a GeForce 6200 class GPU, and 512MB of RAM with Windows XP. We didn't even have hardware that old left in our offices. The closest we could get was a Pentium 4 1.6GHz CPU, a GeForce 6800, and Windows XP with 512MB of RAM. Surprisingly, the game ran well on the minimum spec system after we dropped the resolution and quality settings, but walking around Dalaran was still difficult, with frame rates regularly dipping into the single digits. Blizzard's recommended system specs are an ATI Radeon X1600 or GeForce 7600 GT GPU, paired with a Pentium D or Athlon X2-class CPU. We built our recommended system with an Athlon FX-60 and a GeForce 7600 GT. After seeing how well the minimum spec system held up, it's no real surprise that the game ran just fine on the recommended specification system. Our Intel QX9770 high-end system could probably run this game with a hammer put through three of its four CPU cores.
