Hi,
weve build a prototype app which has been created with Unity 2019.1.14f1 and Vuforia 8.3.8.
When we enable "track device pose" with the tracking mode set to "positional" the app starts to lag on iPhone 6 and iPhone 7.
Were using image targets. The overlays move along with the iPhone when its being moved. When track device pose is disabled everything runs smoothly.
We did not run any tests with iPhone 8 and 9 but with iPhone 10 there is no more lag occuring. Does the setting consume to many resources on older iPhones?
We figured out that its not possible anymore to selectively enable disable extended tracking for individual ImageTargets and enabling and disabling the device pose tracking during runtime seems to work only when we reinitialize the camera along with the vuforia framework.
Do you have any hints how to improve the performace?
Thanks!
Hi,
Hi,
I believe you are running in a issue reported here: https://developer.vuforia.com/forum/unity/known-issues-unity-20191
Could you please try the proposed workaround?
Thank you.

Hi,
I've tested the scenario with the Vuforia core sample apps and can confirm that sometimes, I also saw it moving along with the augmentation.
Hello,
Hello,
It would also be helpful to review your 2D image target that you're using for tracking.
