    Asus G751JT TouchPad Lag (Is there any way to increase the polling rate)?

    The touchpad on the Asus G751JT is very laggy and I just found out that the polling rate of it is only 75Hz
    http://www.softpedia.com/get/System/...-Checker.shtml

    My Lenovo Thinkpad Yoga 14 on the other hand runs at 100Hz.

    both the Asus G751JT and Lenovo Thinkpad Yoga 14 touchpad are connected via PS/2


    it there anyway I can increase the polling rate of PS/2 via Windows 10?

    This doesn't work, polling rate is still 75Hz average according to mouse rate checker

    Tried with both the official driver and the stock windows stuff, but it didn't made any difference.

    Could be a limitation of the trackpad, I need to check the Elantech drivers, try the synaptics drivers instead of Elantech and check where it goes.

    Where can I get the synaptics drivers?

    There is only Elantech driver on ASUS G751JT support page.
