At its core, RealView is not a revolutionary rendering engine but a toggle that enables advanced OpenGL features. During the 2010–2013 era, many consumer-grade "gaming" cards (like the GeForce or Radeon series) possessed the raw architectural power to handle these features, but SolidWorks’ software registry would purposefully disable them if it didn't detect a certified professional card. RealHack functioned by modifying the Windows Registry, effectively "tricking" SolidWorks into recognizing a consumer card as a professional counterpart.
