Hi All,
       Hoping to get a little help here if anyone can.......I am running Carrara 5.1 Pro and i am importing a syntheyes file which runs great....BUT....the syntheyes file also imports a backdrop with it which is a 720 x 480 sequenced JPG. If i click play in the prospective window then it all looks fine at 24 FPS & seems to run in real time. Using the openGL option for the prospective window rendering and putting all the settings possible to off or minimum quality etc but enabling the ' Show Backdrop ' see's my play run speed slow to what looks like about  1 FPS. There are no objects in the window except the default light and about 15 target helpers representing the tracker positions from syntheyes file import. Anyone know why when playing in the prospective window is sooooo slowwww. I am using intel duel core E6600, 2 GB DDR 2 ram, Geforce 8800 GTX, SATA II 250 GB drive. Plenty of power there i think so why the major slowdown with a backdrop showing in the prospective window, its really annoying when previewing animation ETC

Any help / advice would be greatfully received

Many Regards to all

Paul
