There used to be a problem where you would see a white line in the ground and if you crossed it the game would freeze. Now I can see a wide white area across my path when moving. When I see this the game is not loading as I move forward. Does not matter if I am flying or walking, the game cannot keep up with my progress. IF I get near the white line the game just locks up. When it comes back it will often jump back in time in the game.
I had a similar problem (where the game would not keep up with movement progress) before the update that the game would stall while swapping files to keep up but I changed the paging file from system managed to fixed and made it large enough so it would have a single contiguous file space. That made the game run much smoother prior to this latest update. Do I need to make it larger still?
