No gpu maximum performance on maximum performance profile

[AdaSch]

No gpu maximum performance on maximum performance profile when work on battery

any ideas?

i reinstall power manager, driver power manager, graphics driver and still no success

all work ok on ac. I can set speed gpu by option "optimize fan control to:"
1 maximum performance
2 balance all parameters

but on battery this don't work. Always gpu speed is like "balance all parameters".

Some time ago this work correctly.

when i enter to ati control panel and ati powerplay i can manually change speed, but this is no comfortable.

any ane can confirm maximum speed gpu when work on battery in maximum performance profile?

cheers

edit:
solved - max gpu performance newer work on battery.
