When using the Unity profiler I can see Nuitrackmanager.update() uses a lot of CPU. It’s at around 80-90% of total CPU usage. It also alocates like 2 to 3 MB of GC every frame. Any idea how I can reduce this? My application is curently running at 20fps on our touch screens. On my PC it runs at 60fps but on our touch screens which are less powerfull of course it runs at around 20fps.
Could I also have more information about what is important for Nuitrack? There’s only an on-board graphics card inside the screens, could that be the issue? It has a okayish CPU and RAM.
I would like some info about how to optimize Nuitrack and what is important for performance etc. Anything that can help me with general refactoring/optimizing performance.
Anyone can help me? Optimizing this is a must for our project which needs to run on low end screens.
Nuitrack is designed to take not more than 25% of quad core ARM CPU such as in TVico Android Box (or Persee). you can find specs at www.tvico.io. what processor you have? and Nuitrack cannot utilize GPU.
My laptop has a GTX 1070 and a I7 7700HQ. Which runs it fine
The screens it is supossed to run on vary a lot.
A few are:
Intel® Core™ i5-6400
Intel® Pentium® 4415u
Intel® Core™ i5 7200u
Intel® Core™ i7 7600u
My initial tought when out to the GPU because all these screens have are some onboard cards like:
Intel® HD Graphics 620
Intel® HD Graphics 610
They don’t have a lot of ram either. Is that maybe a problem?
they have either 4GB DDR4L 2133 MHz or 8GB DDR4L 2133 MHz
Nuitrack does not utilize GPU, and running on CPU with 30fps uses about 25% of quad core ARM CPU on TVico (with 2G RAM). it seems should work fine with decent CPUs…
odd… Nuitrack does run fine in the Nuitrack test viewer on those screens. Just in the app itself (when the model moves with it) it seems to get really bad.
it seems you need to optimize your app, say, if it requires more than 75% of CPU there will be no room left for Nuitrack process
I understand. Weird part is without Nuitrack it runs a lot better. But I will do some optimalization this week. Thanks for the input and clarification
Please contact firstname.lastname@example.org so we can send you a special version of Nuitrack that can help to solve this issue.
Hi Olga, That sounds great. Any idea what’s so special about that version of Nuitrack that it’s not included in the regular version?
This version of
nuitrack.net.dll assembly includes a static recyclable buffer. Please note that there
can only be one valid
Frame for each frame type. That is, one
Alright, that shouldn’t influence my project. At least not that I think of. Thanks for the PM
