I have Acer Aspire E5-575G-53VG and after windows 10 anniversary update, the touch is so laggy that it is unusable. (Window 10 Hme x64)
The touchpad so laggy that it's literally unusable.
Tried updating the driver via acer download and Microsoft and uninstall/reinstallig the driver.
It seems to be a common issue for E5-575G-53VG with elan tek touchpad.
