Hello I want to report on a bug I had and have now apperently solved hoping it might help someone else.

Since the 3.5.5 update I was experiencing frame time lag when using the WoW 3.3.5 client. Rolling back the update fixed the bug. I tried updating to 3.5.7 to hopefully fix the issue but it persisted and I lost the ability to roll back.

I noticed the frame time lag jump to 60 ms whenever I used the mouse button (joystick touch) to move the camera. After searching a few forums I ended up disabling the “hardware cursor” option in the video setting and this resolved the issue.

I don’t know how this resolves it but I’m not complaining.
