Why is the kinect that slow on my computer. RRS feed

  • Question

  • When using SimpleOpenNI and processing I had a smooth skelleton view, about 30fps. Using VC# and the skeletal tracking example it seems like about 10fps. As if something was blocking it.

    Why is it that slow and how do I make it as fast as in processing?

  • I have the same problem.

    Hardware: win7 ultimate 32bit german, 4gb ram, i5@3200.

    if i start skeletal tracking, the cpu goes up to 100% on all 4 cpu kernals.

    Beta has not push up the cpu.

    The device is at this HW not useable.

    How can i speed this up?

    64 bit!

  • How would 64 bit fix high CPU use? I thought it had more to do with the amount of memory that it could address? My knowledge is lacking somewhat in this area...

  • Focus on the question, what you are saying is irrelevant. If you don't know, don't waste our time with your answers.

  • Are you running in debug or release?

  • Debug, why?

  • Try it in release mode. The debug version has lots of things in it which allow you to debug it, but also have the side-effect of slowing down your program. If you try it in release mode and it is still an issue, let us know.

  • I have try it in debug and release mode. Its the same: 100% CPU

    I check it also with the the Kinect SDK Sample.

  • OPEN NI is this relevant to this forum? I think someone might answer your question but are the open ni guys not willing too? Also, the only thing i can thing of is check processes in task manager for yourprogramname.vhost.exe and end it if your not debugging because sometimes i have programs end and the vhost process doesn't when debugging and I saw that trick on a forum post once about a problem like this.

  • Which sample(s) is/are showing the 100% CPU usage while tracking?

    Is this with the final 1.0 SDK?
