Amd Radeon graphics slower than intel hd 3000!!!!

Hi,
I have a hp pavillion g6-1330se with amd radeon hd 7450m(1 gb ddr3,also with catalyst 12.2 whql) and intel hd 3000(shared).as you see my ati has switchable graphics capability.in Dynamic mode,when i run any program in high performance gpu mode it runs good as it should be.but in power saver it runs like crap.
But,in Fixed mode,when i run any program or game in high performance mode it runs like crap.but on the other hand the power saver runs great.
For example,
Assassin's creed revelations,Fixed mode,all high except msaa,high performance gpu runs at 4-7 fps and power saver runs in 30-40 fps.

Battlefield 3,high,high performance gpu runs at 2-7,power saver in 40-50.

Now my question is What the FFFFFFFF !!!!!!!

 

always game with the power cable connected and on high performance.

And indeed even the mbp 13 2011 can handle me3 while on battery, I didnt even notice any slow downs

 

the results are on cable connected and high performance

 

there is a problem with the power config options, and are you certain that its running in the 7450m?

it could be that the hd 3000 is entering when not needed

 

fardin, have you checked your temps? Could be that when you are running in performance mode, your temps are too high and you are throttling

or perhaps you can try and reinstall the AMD drivers because sometimes a bad install will lead to choppy game play

The Amd 7450 is significantly faster than intel 3000 integrated graphics
