    Ok I see :) I've tried to use vJoy as well but I abandoned because there was too much bugs (but I'll follow up their upcomming new release).
    I totally agree (I've experienced it) about the need for damping, and about the lag introduced by a filter or the 'sand' effect resulting from jitter. Obviously the direct encoder reading with a mcu is the best solution.
    I'll try to get the maximum refresh rate (with low level functions) and see if by measuring time between 2 frames, speed calculation remains good. I'm using precise timing measurements in my game engine (for example the diplay refresh period is needed for animations, and is not stable at all), so it may work. But I agree that windows path is probably the worst, especially considering the various windows versions and all the different hardware out there.

    EDIT :
    I've had a deeper look at your commander app, it turns out you're using "smExecuteFastCommandQueue", which is only available in the simplemotion dll, and not in the open source version I've downloaded...
    Having found bugs in the source of the simple motion lib, I was expecting that it was not the latest version. Maybe if one day Tero answers my last email I'll ask for the latest version of the sources to be able to move on.

    Hi, does anyone has experience using the argon drivers with the simple motion library for a motion rig ? I have all the hardware already for a 3dof setup and i will send telemetry data form a game engine but we are having some difficulties implementing the simlple motion part.
