Way too much GC allocation?

February 3, 2015 - 9:33am #1

Vuforia SDK Version: 3.0.9 -

Description with steps to reproduce:

I'm using Unity and have begun to optimize this project. To my surprise, when I pulled up the profiler, I found that Vuforia is allocating 0.9 MB of garbage EVERY FRAME. This triggers a garbage collection about every 4 frames, which is an awful lot of stuttering. Is this expected? Are there any plans to fix this in future versions? Are there any settings or techniques I can use to minimize these allocations?

I checked on two different projects and both had this issue.


Development OS (Mac OS X, Windows, Linux): OS X 10.9 -

Mobile OS and Version: iOS 7.0.4 -

Mobile Device Manufacturer and Model name: iPad 4 -

Do the Vuforia Sample Applications show the same behavior?: Yes

Do you see any stutter or considerably low frame rate when running any of the Vuforia samples ?

In our tests, performance on iPad 4 are generally good with Vuforia.
