Quote: "Unity3D has embedded the engine in the software, which basically means you can't update the drivers without updating the whole package."
While this gives you less flexibility to update faulty drivers, it does remove the "I'm not going to litter my computer with yet more junk just to try out a demo, so I won't bother" impediment.
And if a lot of people are like me, they won't try out a demo that requires "system stuff" to be installed.
Between the two evils, I'd personally much rather have a statically bound DPhys rather than the current setup.
I have vague plans for World Domination
