This is the first I've heard of it, not sure what could be causing this. Nevertheless I'll take a look and see if I can do anythingHey making a post again in case it hasnt been seen. But I'm pretty sure there is something in the menu layout that is causing a huge increase ein CPU usage. The game speeds up fine when going through the story but lags heaps when I right click to make a new save.
This is the first time a game has such laggy menus too, even more than games like Broken Dreamers or Deliverance. Please try to optimize the menu, its really messing with game plays for slightly less powerful PC's :')
