One VERY important thing I'd like to mention is that if you've got this or a similar graphics card, it is IMPERATIVE that you change "Post Processing" to "low" in the graphics settings. It will improve the performance of the game SIGNIFICANTLY and it will also look much better especially if like me you're running the game at a resolution of 1366 x 768 on your laptop screen. Setting "Post Processing" to high made the game look quite blurry. A bit like looking at an image who's resolution is much larger than that of the screen. Setting "Effects" to low will also improve performance but not as significant as "Post Processing".
Settings that I use to get approx 30-38fps
I'd like to point out that I've set most of the settings on medium just to get a slight increase in performance. I suggest you play around with them to see what will work best for you. If you have a gpu like mine, you should be able to play on high quite well so long as post processing is low. All in all, it's an amazing game and highly recommended. Here are a few screenshots I took. Another thing is that I set the first option to full screen instead of windowed because it allowed me to alt+tab to another window without closing the game.
