E6530 with Win10 jumpy touch pad.

Clean install with win 10 pro on my 6530. Love 10 over 7 pro now but my touch pad is jumpy,not as sensitive just plain doesn't work as well as in 7. Also lost the one finger scrolling which I liked. I tried many different settings now for over a week. Tried changing drivers as well. I wish I could install the old software and driver to get the same function again. Both were 64 bit pro.
