So for what it's worth looking at adopting libinput would likely improve your touchpad experience.
You should investigate if you are using that after upgrade. It's the default with 17.10 fresh install but I don't know what would happen with upgrade. PS2 mode doesn't support as many features as I2C does. If you still aren't happy with the performance in I2C mode you should be able to adjust many options in libinput that can better improve it than switching to PS2 mode offered.
