Frame-rate Issues

[Kritz]

I didn't make myself clear, sorry. When the game cycles to night time, the game becomes unplayable for me. 1-2 FPS at most. The game runs absolutely perfect at any other time of day, including the fade from afternoon to night. It is the moment that the game reaches night that it becomes unplayable for me.

I have tried turning down every setting. I have gone into .ini files and attempted to remove shadowing, reflections, etc from the game. I have tested in different cities and different times of day with different graphical settings. Night time drops the performance down to nothing.

Is there a way to disable night time during the story mode? Or is there a known solution to this issue?

I do have alternate hardware to test on if needed, but I'd sooner ask here.
