Rampage, this is the sort of issue I am having too. Before patch 3.02 in WoW it was fine, but since then I have been getting the following toon doing very weird lagging things.

Ive got my video interface set to minimum, it is still happening. Resetting maxfpsbk and maxfps doesnt seem to have helped either.

Im wondering if I need to delete and re-install keyclone. Ive tried resetting it to its defaults.
