A long time ago, I had the chance to test out World of Warcraft: Dragonflight on the Steam Deck's LCD, and it ran absolutely great and it will only be better now.
A big shoutout to Hill+Knowlton Strategies Strategies for providing me with a key and some game time for this test. My apologies for the delay in getting this out.
Firstly, you still have to run the through Battle.net. For those looking to install Battle.net, there's an Easy Launcher installers guide here. By default, WOW: Dragonflight sets its graphics to the low preset, but you will want to set this to level 5 (good). It also automatically sets the anisotropic filtering to 16x and runs with FSR 1. While this configuration works well and offers a decent performance, you will want to remove FSR in favor for point.
In the early stages, especially if you choose the dragon route, the game performs and looks fantastic. However, later in the game, when you zoom out and see more of the world, the FSR 1 pixelation becomes noticeable, particularly in older game areas.
Regarding controls, World of Warcraft is traditionally a mouse and keyboard game without native controller support. But there's a great community layout called 'WoW Keybinds' by Dwarf, specifically for the Battle.net launcher. Initially, I found the mouse movement set at 275% sensitivity a bit too high. Reducing it to around 150% felt more comfortable and made navigating in-game easier. If you're finding the sensitivity too high, I recommend adjusting the joystick mouse sensitivity.
Also, I suggest enabling 'Auto Loot' in the options for convenience. Additionally, tweaking the camera following style to 'only when moving' makes the game feel more like a standard controller-based game.
In later game stages, turning off FSR 1 off (Fidelity Super Resolution) and switching to point sampling provides a great view even on low settings. The game runs impressively well and can be enhanced to 'good' without FSR for a high-quality gaming experience.
If you're considering diving into World of Warcraft, keep in mind it's still a subscription-based game. Or, if you're more nostalgic, maybe give World of Warcraft Classic a try. Let me know in the comments if you'll be exploring Azeroth on your Steam Deck soon!
