Update to previous post...
Although I had a crash 30s in just after updating, I put this down to network issues, and that game has played okay since then (rebooted the hub and PC).
However, I have noticed that the anti-aliasing on fine lines is wrong - especially noticable on orbit lines and gravity well rings (blue). I say "wrong" and not just poor as it looks like its being applied in reverse - as the line transitions across pixel boundary it fades out, but does not fade in on the new raster line, producing an elongated beaded effect.
This seems trivial, but is very distracting as I have never seen pixelation before on my current rig.
