Last week I discovered that Blizzard was handing out 7 days of free time for past WoW subscribers. Being the cheap, curious bastard that I am, I took advantage of the offer to both play for free and to check out the most recent patch. WoW recently underwent a major overhaul in preparation for the Mists of Pandaria expansion which goes live on September 25th.

A profound feeling of "holy crap there's nothing to do" pervades WoW right now, and as a result I didn't really spend a lot of time actively playing. I spent a few hours dueling other players and PvPing in battlegrounds; I also did a little bit of brushing up on my classes via Elitist Jerks and Arena Junkies since I haven't played in months.
System Requirements and Performance
World of Warcraft was originally released in 2004. This is obviously not a super-demanding game by today's standards. Still, Blizzard has continued to make subtle tweaks to the game engine to keep things looking pretty. You've gotta admit, WoW is probably the best-looking eight-year-old-game around. I wasn't able to find a specific list of performance tweaks and visual improvements, but I did find this "blue post" from a Blizzard employee:
There are actually quite a lot of graphic engine improvements in Mists of Pandaria, however for the most part they are subtle. For example, improved shadowing, blending and enhancements to the fog effect.
Amongst the large list of information we hope to share with you is included a list of the new graphic engine improvements with some before and after screenshots to highlight what each one brings to the game.
Each one might be subtle but as a whole they bring an improved visual appearance to the game. :)
