I ran across this while trying to find my own solution. It would had been nice if this had been answered. I'm trying to create VMs to replace computers for family (and use cheap tablets or notebooks to access the VMs.
Games that require OpenGL (like Minecraft), won't work without OpenGL drivers. OpenGL is a graphics API that allows the program to tell the graphics card how to render shapes. Even in a virtualized environment, you need that graphics layer to do the rendering, and if the program is written to use OpenGL, you either find an OpenGL driver, or you can't run that application. There is no substituting for DX or anything like that without asking the developer to rewrite his entire graphics engine for a new API. It ain't gonna happen.
Thus, if anyone uses applications for OpenGL, they need this driver for VMware.
