Oh, yes, it will work, but the OpenGL drivers aren't installed by default on many PCs.
But isn't that the same situation with DX drivers? By which I mean that the default drivers are usually useless.
I have a brand new Dell GX280 at work and I had to update the drivers myself to get Blitz3D working at a decent speed.
And at home I also have one of those Dell laptops that Dreamora talks about above that Dell only supply NVidia 27.something drivers for and I had to go hunting for later hacked drivers myself to run stuff like Call of Duty and Half-Life 2.
So what makes OpenGL support any more difficult or troublesome than DirectX support on these types of PCs?
Edit: Don't get me wrong, OpenGL still puts me off BMax, I just think the scale of the problem may be being exaggerated.
