Update after some playing around and testing further:

I have all setting on the highest possible because I like my game to pop. If I change the

value to false in the GraphicsRules.sgr file it instantly fixes the problems:

  • My system doesn't lag
  • I can happily tab between apps whilst the game is open
  • FPS jumps to 50-60
  • Overall gameplay is a lot smoother
  • The awful lines have disappeared (see screenshots in my opening post)

Changing the value back to true instantly brings the problems back. The downside is that my game does not look as good because of the shadow changes, not what I would expect from 4GB and 8GB GPUs.
