Since 1.4. I have a weird lag in the shipmovement when the fog of war needs to be refreshed. You can see the ships jump from tile to tile so that the the FOW can be recalculated, it is not a smooth movement at all. If ships move within space that has no FOW the movement is a smooth flight.

Can anyone else confirm that?

I'm running an Acer Aspire VN7-791laptop with Windows 10 home and a GeForce GTX 860 M graphic card. Before 1.4 the movement of the ships was always smooth, even if the FOW needed had to change. Also the overall performance of the game is very good. And since nothing on my machine changed that would explained this, I would think the 1.4 update is responsible.
