It appears that the upcoming World of Warcraft Classic demo is already playable for some enthusiastic fans.

The demo client went up for preload last week for those who purchased a Blizzcon 2018 Virtual Ticket. Datamining revealed some interesting details about the upcoming demo, including modern visual settings and the addition of a Classic button in the system pane. We already covered some comparison shots between the modern Ultra High graphics settings and the original ‘Classic’ settings, and this new comparison video from Dodgy Kebaab shows some more interesting tidbits.
