Yes there is, to answer your original question it's technically the same engine, but a much evolved version. So it's yes and no... Awkwardly 😀
It's a shame it's not backwards compatible too. Would love to run through HL2 with the updated EP2 graphics engine.
Would it run on a new MB? Probably not. Looking at the system specs it'll run okay on my iMac with it's X1600 graphics card. So you might get it running on low. It's the graphics card that lets it down, everything else is perfect.
