For the guys running motion rigs - FlyPT or Simtools?

I’ve got an SFX-100 based motion rig, and have been using Simtools since MSFS was released. I have that annoying stutter every 10-20 seconds related to Simconnect. I’m wondering if the guys using FlyPT are experiencing the same stutter? Considering changing over.

I am using Simtools with a DOFReality H3 platform. Are you saying that the stutters are associated with using Simtools? I do have some stutters, but, there occur whether I am using the platform or not.

I get a lag spike every 10-20 seconds whenever simconnect and game manager are running.

If I kill Game Manager, all the lag goes away.
