I somehow had the idea the open source drivers would be CPU limited. No multithreading with catalyst too, load < 25% for a 4 core CPU? I asume 100% is full CPU utilisation. Would be great if one of the driver developers could comment on this.
To the Phoronix and Michael critics: Stop derailing the thread! Want to whine about it? Get you a fscking blog!
I think you might be right. Single threaded apps will have a lower cpu utilisation - would be great if we could see the utilisation of each core during the test
