From that thread:
"If you notice that the mouse pointer freezes randomly and everything goes slow then you might be affected by the “Double Clock Speed” problem.
Make sure this is your problem:
open: Applications – System Tools - "System Monitor" (from the menu in GNOME). ... Click on “Resources”: you will see “CPU1”: and the percentage of usage of your processor. If the percentage is high (try this without any programs running), i.e. something like 50% or more then you have this problem.
Another test: play an mp3 in Totem (or another app). If it goes too fast then you have this problem"
My mouse pointer never freezes randomly, my PC runs very well. No unusual CPU load in System Monitor. My mp3s play at normal speed and always have. Judging from these tests, this isn't my problem. As I said, it seems to be a GPU issue rather than a CPU issue, and the problem doesn't exist in any game or OpenGL application besides Ryzom.
