We have had some reports of users experiencing an issue with the game graphics after updating to the GeForce Driver 378.49 with a GeForce 10 series video card.
To workaround this issue, open the Factorio properties in steam, and set the launch options to:--max-texture-size=16384
We hope Nvidia will be able to address this issue shortly, if not we will release an update to limit the texture size by default.
Update: Nvidia released hotfix driver 378.57, but it doesn't fix the issue in Factorio. So we have limited maximum possible texture size in our code and released 0.14.22 to address this issue.
