i grabbed the "BF3" 11.10 catalyst preview last night, haven't rebooted post-install to get the CCC GUI installed (Win 7 x64) , but so far, restarted cgminer 2.0.5 on intel, and no single thread usage anymore, which is nice. will try 11.10 preview on another machine, but i think it will have the same effect, which should be great for thermal testing as it's a WC rig in a single loop.

so far, the CPU is pegging 4-9% for normal windows ops with chrome running, where CGminer used to have 13% by itself, it's down to 0/1% and 47 seconds CPU time for ~2 hours.
as for cgminer performance, it's ~388.6mh/s and 70'c on defaults, so it looks to be pretty consistently normal on HD6970.

haven't installed BF3 from the download, but it seems to load other games just fine. i usually leave cgminer running while gaming, and doesn't seem to affect FPS, but i'll test it later for other apps for any other performance issues.
