eON Technology

eON Technology, also popularly refereed to by name of the company, "Virtual Programming", is a monument to the extraordinary efforts that some developers will resort to, to avoid any other platform beside Windows.

This is not general emulation, it is specifically crafted for the game and the target hardware. This introduces quirks that are familiar to Windows users but alien to Mac and especially Linux users. Such as the game requiring a specific subset of drivers for a limited set of hardware. Where as "OpenGL" or even "OpenGL 3.0+" would be a typical Mac or Linux requirement for a 3D game, a game using eON might require "NVidia 340.65 only" or "fglrx 14.12 only" and further limits users such as "Radeon 7000 series only". Again, this is game specific. Just because a certain eON game supports certain hardware and drivers, doesn't mean later games will also support them. They will support a different set of hardware and drivers. This means if a player can run a certain eON game after they upgraded hardware and drivers, playing the next eON game will require an additional set of hardware and drivers and the first eON game won't play anymore.
