TobiiXR SDK generates lag

Recommended Posts


I recently added the TobiiXR Unity plugin to my Unity project to collect data as to where (which part of an npc) a user is looking during the experience. I use a HTC Vive Pro eye headset to collect the eye tracking data, using the sranipal software. However, the Tobii software has a very high usage according to my Unity profiler. Starting the project with the Tobii software enabled makes the scene laggy. Does anybody know a solution to this problem, because I wouldn't think that eye tracking uses that much resources. 

As seen on the profiler screenshot below, the blue is almost 100% tobii software. Even an empty scene is laggy with the software enabled. The function that takes much time is called 'TobiiXR_Lifecycle.Update()'.


Thanks in advance!
