Is there suppose to be a delay in mouse movement. It seems really slow and a long reaction time. Its extremely annoying. Don't know if its something wrong with my game or not.

hey mate, glad to read someone else is having the same problem. I didnt notice any lag the first time i logged on and played (being the only time i've been on so far). But have noticed the problem on "main screen" of the game recently when attemtping to connect to realm. Im sure its nothing and they'll have it fixed ASAP. Though i am a complete noob and tried adjusting my mouse sensitivity to fix, haha so nothing im writing should be taken as fact 

Turn off Vsync

Vertical Sync doesn't have anything to do with your mouse.  If you are seeing a delay with your mouse, head into your game options and try checking the box that says "Use Hardware Mouse."  This will cause the mouse to take commands from your actual mouse install instead of using the cursor provided by the game.

Hey um i did check Use Hardware Mouse and that problem is fixed but im having a problem with movement on my character in-game. I cant move around without lagging and ill be in one place and then "teleport" to another spot. Anybody know how to fix this problem?

 Guys, you fix this problem by setting your flip queue size. If you are using an ati card, pick up ati tray tools, just do a google search. after its installed, right click the tray icon, and hover over 3D and click Settings. Click the tab Additional.  Near The bottom you will see a drop down box called Flip Queue Size. Select 1. Then hit Apply.
