Well you could improve performance by modding the game and tweaking with the video settings. There is a really simple way to achieve this as well. Here's a video that I found that works. The tutorial part isn't great but it does show where to find the software. It says FPS but it should generally help in performance as well as you can disable intros and stuff. http://https://www.youtube.com/watch?v=AHcbEnjXIYw
