That may shed a light on how graphics drivers or other factors influence 
performance at application level.
I just tested KDiamonds here with Qt4.4.3 and although I dont quite understand 
the rules, all animations where perfectly smooth and playable. Driver is 
radeonhd as chosen by Opensuse.

In any case it's good someone tested digikam with Qt4.5 and it works! :-)
