Improved workload tuning

[me.scotty]

this is implemented by the driver. it automatically clocks down if some threshold is reached

In my case, I got a hard crash (exception) inside oclHashcat, leaving an intermediate file (.new)
This might due to the 11.4 Catalyst I'm using.
I've been reluctant to update because of the past cautions...

Try CGminer

Thanks for the suggestion. This looks promising.
With my current setup (11.4 Catalyst, single card), when I'm running oclHashcat, I can do simple web browsing, file editing, etc. without problem.
However, if I try to watch a video, I get an immediate screen lockup (GPU activity goes to zero, based on the fan noise), which can only be resolved by a hard reboot. Not so good.
