It has been known widely that Mac machines failed miserably when it comes to gaming. Its more prove when Steam launches “Steam for Mac”, with titles like Portal failing miserably along frame rates of under 40, whereas the same machine running Portal on Windows 7 using boot camp faired better with decent frame rates of above 60.

Many users of Mac has been whining and raging due to such issue, and Valve has responded that major improvement will be coming as they work together with Apple, ATI, and Nvidia to layout the problems and fix the issue. Things like OpenGL and drivers will be optimized along the way.
