I'm currently developing an app with the latest unity plugin, and I'm having some trouble with very low camera FPS (approximately 3-5) on a brand new Nexus 10. The actual unity scene is running at a smooth framerate, so that's not the problem. The camera FPS is reasonable when the AR target isn't in view (probably 15-20), however there's a pretty obvious delay of about 0.5 seconds between moving the camera and the display updating. When the AR target is in view, the FPS drops, and it becomes especially low when moving the camera very close to the target. In comparison, the bundled camera app runs at a fairly smooth framerate with almost no delay.
I've tried a very simple 3D scene with just one standard unity box, there's no obvious difference in framerate. I've also tried to minimize shutter-related frame drops by testing the app in a very well lit room. Furthermore, i've tried playing around with some focus mode settings via scripts as well as the camera device mode settings both via scripts and the inspector view, there's no visible difference though.
Any ideas of what might be causing this, or is the Nexus 10 simply not fully supported yet?
Thanks in advance!
