Graphic Card radeon hd 5470 playing Crossfire , problem with scaling

Hi there.
My problem is.. i play Crossfire game in full screen (dextop and in game) and after one hour my fps is decrease 100+ normal to 50-14 and after my dextop resolution 1366x768 is go on resolution 640x480 and scaling "Full Screen" is changing.

So.. i have black borders but not on game , on dextop and i think this is decrease my fps
After change i tryed to change them back but worked only with change "personalize" with "windows clasic" and not windows 7 but when i try to play game is asking me if i want to change settings yes or no. if i press yes i go back to black borders on dextop , if i press no .. i don't play game
i need to restart laptop for play again one hour and again
