Hi @vadim.bazhin Thank you for your reply. I am now smoothing the data as needed within my application itself which works for me. However, I now have bigger problems as the issue I described in this post seems to be back: Nuitrack App crashing with Astra 2 Recently, whenever I open OrbbecViewer my Astra 2 camera is listed as a USB2.0 device rather than USB 3.0, and then Nuitrack crashes when I run the demo app. This was previously working but has recently started failing again. I haven’t changed anything in my set-up expect possibly a Windows update. I’ve tried re-installing Orbbec driver, upgrading to latest Nuitrack, upgrading all other drivers on my PC but nothing has worked so far. Any help would be much appreciated. Thanks.
