I have a laptop with Intel integrated GPU graphics, and I can't squeeze 100 fps out of this card in D3D mode, while the game hangs periodically when using OpenGL.
The graphics are worse in D3D. Given that OpenGL is a better opensource graphics library, shouldn't it perform better then something devised by Microsoft?
What can I do to help this? Would upgrading to a i5/i7 processor with Intel HD Graphics solve this issue? Do I really need a dedicated graphics card?
