Game crashes to desktop and performance issues

Game crashes to desktop when i try to open an assembly line to change the vehicle type and quantity to produce. It crashed over 5 times on a row when i tried to change the production chedule. After 6th reboot of the game it worked again.

Also mayor performance issues when playing the giga factory map (biggest standard map). Game is unplayable. Slide show. picture after picture. Placing anything you just need to wayt 30sec for it to spawn. HORRIBLE!! I got AMD FX 8 core CPU 8350FX and 16GB ram and SSD HDD. And a big games GFX. CPU does not get above 20% yet the game lags like a whore.
