Limited Framerate

[joh_cb]

Hello all,
Please help, my frame rate never gets higher than 44 fps. does anyone know the solution?
comp spec: i7 3610QM, 8 Gb RAM, Win 7
Orion 3.2.0 on USB 3.0

thanks in advance

You may be running into bandwidth limitations on your USB host controller. Try swapping to different USB ports to see ifthat helps the framerate

ok, thanks for your reply.
I've tried all my USB ports, including version 2.0. it's all the same.
After a few tweakings, I found out that the low resource mode causes this.
If I turn it off, the frame rate goes up to 115 fps but in Unreal Engine it jitters (I use leap motion to control camera position).
If I turn it on, it works smoothly in UE4, but the framerate can not catch up with UE4 as it's only 43,9 fps.
is there any way to tweak this low resource mode setting to run at 60 fps?

The jittering that you're experiencing is the result of sampling the most recent frame from the Leap Motion software when it's running at full speed. The effect is analogous to videotaping a television screen using a camera that captures at a different framerate.

The Unreal plugin currently has a timewarp implementation designed for the HMD (link here) but it is largely undocumented and would have to be reimplemented for a desktop screen if you wanted to apply it to your use case. A more straightforward solution would be to use a Kalman filter and apply it to the Leap positional data and associated timestamps.

ok, very useful information Alex. I guess my problem is solved for now. Thank you very much
