Hello,
I tested on another machine of AMD CPU + Nvidia graphics card, and the
performance is very very good of frame rate even beyond 60. Also I tested on
AMD CPU + AMD R515 graphics unit, and the performance is as bad as with AMD
780E. Just provide more info of Clutter on AMD graphics unit that may be
helpful to other people.
