Windows Anniversary patch makes my touchpad laggy

My laptop is Aspire E14 E5-475G-30KY(1 week old), it automatically updates to the new Windows 10 "Anniversary" patch. That is when my touchpad lags, I think ELAN touchpad drivers stopped working because Windows 10 use their own HID-compliant touch pad that is OUTDATED, driver date 21/06/2006. I tried disabling HID-compliant and touchpad doesn't work(obviously), so I think that's the issue, but I don't know how do I fix this.

I already uninstalled ELAN drivers(touchpad works but still laggy just the same), reinstalled from my models driver site, and tried updating it to the latest 13.6.5.2 and it still lags from time to time.

I hope anyone can help me.
