I'm getting dropped frames (duplicate frames, that give a bit of a stutter/jerky/less fluid experience) running the Image Targets sample with Vuforia 2.8.9 on a iPhone4S (iOS7). Tried both MODE_OPTIMIZE_QUALITY and MODE_OPTIMIZE_SPEED.
I've read https://developer.vuforia.com/forum/faq/how-can-i-improve-detection-and-tracking-stability and assume the reason for the dropped frames is that the iPhone4S is not powerful enough.
On what devices (iOS or Android) should I expect to be able to run the Image Targets sample without dropped frames ? (assuming lighting conditions etc. are good) I need extended tracking, and the user should be able to pan away from the marker.
Many thanks in advance!
