Found what generates & regenerates the xorg.conf & patched to include the tearfree line.
Users wishing to test can get an patched ubuntu-driver-common here, instructions on page to get going & how to purge if unsuitable.

Note that it's for Trusty only

Title:
  Nvidia-prime produces unbearable visual stutter

Status in nvidia-graphics-drivers-331 package in Ubuntu:
  Triaged
Status in nvidia-prime package in Ubuntu:
  Triaged

Bug description:
  I've installed NVIDIA-Prime v0.5 on Ubuntu 14.04 with all required
  dependencies, on a Clevo 355STQ with a 765m.

  My issue is that whilst the new switching feature works very well, it
  still produces an extremely noticable amount of visual stuttering. In
  graphical and applications and games I can produce very large frames-
  per-second numbers yet the amount of visual tear makes the program
  unusable. Vsync/Sync to Vblank/vblank_mode=1 also does not work as
  intended, with tearing still present.

  Has anyone else had this issue or found a fix?
