GemFX is graphics enhancement add-on that allows users to apply a wide range of visual effects and improvements to certain games. It works as a shader injector that overrides a game’s default graphics effects. GemFx works great with Guild Wars 2 and installation is relatively easy, plus there is no risk for getting banned for using this add-on since it doesn’t violate GW2’s terms of service. This guide will show you how to get GemFX up and running with GW2.
