Can I download different drivers/software for my ASUS touchpad?

Hi! I have an ASUS x83vb-x2. Love the computer, hate the touchpad. It jumps around when I type, the scrolling is difficult, and it's hardly customizable. It uses Synaptics, and the latest driver is installed. I don't know much about this stuff, but I know that I can't stand the touchpad anymore, and that the touchpad on my brother's dell is a whole lot better. I was wondering if there are any drivers or software that I could download and use on my touchpad that would let me customize sensitivity and let me program multiple finger functions and just make it better all around. Like, can I download and install dell touchpad drivers? Any help / explanations to someone who obviously doesn't know anything about this would be appreciated. Thank you!
