Mike:
Uppps forgot to attach bench log.
Done.

I don`t think changing high prec timer is a good idea for stock development.
Especially for hosts which are used for other things than crunching.

Yep, I will not do this default, at least before quite prolonged testing. It's system-wide change... So -high_prec_timer will not be enabled by default in next release.
Raistmer:
In next testing window please try with CPU busy and mandatory -use_sleep option too.
There is one very important difference between your GPU and my C-60 regarding this test. My C-60 one of slowest ATi devices so get low-perf path with sleep enabled by default.
Hence I omit it in testing (still going, BTW, on netbook).
And all changes between these builds embraced with if(use_sleep) so to enable sleep is requirement.
EDIT: and as usual these days, seems you need some full-length tasks, not PG set. GPU too fast.
For example, all CPU time you see most probably came from startup code, not icfft loop processing.

You said no tuning line at all in your post above.
Thats what i did. :(

CPU fixation to 1GHz reapplied after reboot.
Binaries used for this test attached so reader can repeat it on any ATi GPU equipped host.

Short instruction what you want would be helpful.
Will test with CPU busy and _use_sleep.

Here is my bench with busy CPU using -use_sleep.
