Hi @artfwo, thanks for the quick response.
I’m pretty sure I reinstalled it correctly, I can try a uninstall/reboot/reinstall/reboot cycle just to make sure the windows services are cleared out.
Good news though - I’m connecting directly to the arc via serial in TouchDesigner, and have already converted all the relevant api calls. The latency is incredibly low (especially using a 120fps patch) and the sensitivity is absolutely out of this world! Haven’t had any drops (other than crashes of connection when sending invalid commands accidentally during testing, a quick unplug and reconnect resets everything just fine). I’ll probably stick to serial for my custom applications, though I’m hoping the win10 issues for serialosc get solved for using other people’s Max patches like Capstarc. Thanks for looking into this!
