What is needed to enable it again?
I have installed the synaptic drivers from acers homepage but it did't do anything but add a useless tab to the mouse settings in control panel. (which SHOULD contain the settings for multitouch but doesnt)

Acer updated their site with the drivers for Win8 for those of us upgrading so you should be able to find the appropriate drivers there (note that those on Synaptics' site are outdated).
Also, as @ernie mentioned, you should probably be using Elantech's drivers (those at least were the ones working for my S3-951).
Downgrade the drivers, then reupgrade them:
