Hi,
Posting again, first was considered spam, don't know why.
I'm developing a software to control motion rigs for simulators.
There, we calculate the actuators positions.
The idea is to send those positions to Fusion360 and preview the result in the model.
Many use Fusion to design their rig, and that was a way to preview the result.
So I made a C DLL to get the values from shared memory, and update the joints.
Problem is that each time I update the joints, it takes around 3 seconds to update it in Fusion360.
Is there a way to make it faster?
The software:
Message box shows elapsed time to set 6 sliders...
The current code to test it:

#include <Fusion/FusionAll.h>
#include <CAM/CAMAll.h>
#include <Fusion/Components/RevoluteJointMotion.h>
#include <Fusion/Components/SliderJointMotion.h>
