Perfomance troubles displaying a HD movie with g43 and display clone

Hello

My g43 looses some frames watching some HD movie and enabling display clone option,

(with DVI and VGA outputs enabled at 1920x1080 60Hz).

The video driver does not have any problems disabling clone displays;

it seems that video driver use 2 memory buffers, one for each output, for the same resolution...

why? thanks in advance
