The game runs fine and the tile disruption is so rare that only once in a half an hour or so 1 tile on the ground is wrong, but if I
turn away from it then turn back it's fine. It was freezing up some times before I did this and that stopped too. I have been playing
for a few hours now with no problems. Turning 360 degrees it still looks somewhat abnormal for what your used to in a game but
not too bad. This worked for me, just though I'd share my experience.
