  Finally, killed that bug with 11.12/2.1 combo. Zero cpu usage with AGGRESSION=12! Thanks to ssateneth and his thread.

I hesitate to use 2.1 SDK, because I want to use the computer during mining.
I've noticed that the CPU usage increases gradually with miner agression:
0% of single core usage at Aggression 8; 268 MHash/s
0% at Aggression 9, but screen updates became laggy
12% at Aggression 10;
50% at Aggression 11
80% at Aggression 12
90% at Aggression 13; 273 MHash/s

Why you can't use it during mining with 2.1? Have no problems here, even playing in Skyrim without losing mhashes. I use internal 4250 to offload 5770 tho.
