Astarth (atys)Under linux, 100% CPU usage means 1 core.
given those obvious issues i took a look at the system monitor and found that only running ryzom i was using all 6 cores at 90-99% when ryzom shouldnt be using more than 3 at that capacity
To launch second ryzom in separate core, you need to use taskset utility.
To run ryzom on first core, you would launch it as
taskset -c 0 /opt/ryzom/ryzom_client
second core would be
taskset -c 1 /opt/ryzom/ryzom_client
