It can effect alot of different things. I would still recommend you set EVERYTHING to low, and make sure to turn off all other things like Anit-Aliasing, etc.
Also, what resolution are you running your game at?
The optimal resolution for my laptop is 1920 x 1080
That is probably too much for your integrated graphics to render. Try turning the resolution down and see if it helps.
Unfortunately knocking the resolution down didn't work. I am considering uninstalling the game, like a clean sweep.
If you want to try a fresh install, go ahead and do that, it wont hurt to try.
