acer aspire e 15 e5-575g-39m3 laggy touchpad, system interrupts high cpu processes

hi. i had bought e5 575g 39m3 about 1 month and i has some issue
System interrupts high cpu processes when i use touchpad (advanced touchpad Bios) 5-15%, the mouse pointer is very laggy
I had install full driver (IO driver, synaptic driver...) but issues still unimproved. I tried change to basic touchpad, this issue has solved but two finger scrolling doesn't work.
