I think that you should support graphic cards that look like for example. 670M and 680M for Nvidia cards because It runs far better on another computer I have and it has a 510 nvidia graphics card. I'm thinking this is the issue and I would love it if it was looked at being this. Also if I could get a response if this is even an issue being this specific.
Mobile editions of GFX cards tend to be the last desktop model shrunk down into the right form factor and tweaked a bit to use less power. When they do the optimization work, this should fall into place on it's own.
What broken says is mostly true. Mobile performance, unless you buy a machine designed for it, tends to be at least one generation behind whatever their claimed numbers are. Seems like it's getting a little better, but my 6770M in my Mac Book performs significantly worse than the 5770 desktop I had in my machine for a while, despite having more memory and a much faster processor than than my desktop had. :/ Sucks, but such is the nature of laptop graphics.
