Increasing Camera Frame Rate - Vuforia Slow Performance

November 24, 2017 - 9:49am #3

Hello

Camera latency within my Vuforia enabled Unity app is causing motion sickness, similar to low frame rate VR.

Generally I am seeing poor performance using Vuforia, despite trying the below.

 

Vuforia's Configuration settings

  • Set Device Mode to 'MODE_OPTIMIZE_SPEED' 
  • Set Application frame rate set to 60fps
  • Added 'Frame Rate Settings' to the AR Camera
  • Disabled Smart Terrain Tracker 
  • Disabled Device Tracker 
  • Enabled Load Object Targets on Detection
  • Set Max Simultaneous Tracked Images & Objects to 1

Unity Application

  • Reduced application resolution to 200 DPI
  • Removed Debug.Logs
  • Checked general performance
  • Set Quality Settings to 'Fastest'

Tested On

  • Samsung Galaxy Tab S2
  • Samsung Galaxy Tab A

 

Question 1.) How do I increase the camera frame rate?

Question 2.) I have 17 image targets in my Database. Can the amount of Image Targets decrease performance?

I had a user login input field. When disabling that (so the keyboard didn't pop up) I had a big increase in performance.

Question 3.) Does the native Android keyboard pop up still effect performance? (and is a fix on the way?)

Thanks

Jim

Hello Jim,

This issue you are describing with the input field is known by our team. We were able to track it down to be an issue within Unity and are currently awaiting their fix for the issue. Unity has marked it as resolved, so it will presumably be fixed in an upcoming Unity build. I'll be sure to provide you with updates on this as they are available to us.

To my knowledge there is no work around, but if I find any I'll be sure to share that as well.

Apologies for the inconvenience,

-Vuforia Support
