I've recently got to Skellige on my second playthrough and I've noticed the same graphical issue I first noticed last year when I first played through the game. Some of the grass/ground detail and shadows seem to render in a line around 15m in front of Geralt and continues to move as I move forward through the world. This doesn't happen in Velen or anywhere else though.

I've got the game on max settings and all my drivers are up to date, etc. I've also modified the user.settings file and some things in the nVidia control panel but that's made no difference whatsoever.

Was just wondering if anyone else had this issue and if there's a fix for it.
