    Due to a lose usb cable I had to rework all my configuration (to understand what is was wrong) and I updated my SimTools version to the last one and the iRacing plugin as well. I always thought I had some kind of weird issue on my configuration, because I always got this strange jagged movement when I'm driving below 20 kmh, so when I updated everything I expected to solve this strange issue as well. But guess what? With the update some things are changed but not that one. So I'm asking, is that really what iRacing output in that situation? Are they using a super approximated phisics on their cars below 20 kmh? Do you have that as well or is it just me?

    My Motion Simulator:
    2DOF
    This might be a late entry, but I've had the same thing happen after I upgraded simtools to the latest version and also upgraded the resolution on my prosimu controller box. I also started tuning with the actuators full range opposed to using axis limiting (10 cm Vs 14,25 cm). Just mentioning this as it might be relevant.

    Anyways, I feel I get more unpleasant back and forth movement at slow speed or just before I reach a stand still when the difference between max/min of surge is big. In my case 1/-1.8.

    That said assetto Corsa is worse and I had to use some smoothing to get rid of it.

    I believe surge fluctuates alot on low telemetry output +/- 0.2.
