If you have not had an opportunity to read Azuriel's post "The GW2 QuickStart Guide" over at In an Age you need to check it out.
He reviews number of ways you can improve your in-game enjoyment. He explains how you can get 10 - 20 fps by toggling some settings. He points out to improve keyboard control and did you know there is auto-looting! Did you know you can auto-sort your inventory? Do you know where all the Asrua city portals are? What about collecting materials for crafting? Azuriel has it all figured out.
Go by In an Age and check it out, you'll be glad you did.
