Having the same problem - "Disconnected from Server" upon starting a new singleplayer game, after the loading screen.
Changing texture resolution to medium (or any other setting to low quality) does not help. Anyone having the same problem? First several hits on Google (4GB RAM patch, disabling secondary screen, etc.) did not help either.
Win 10 Home / i7-6700 / NV GF1060 / 16 GB RAM
