1. Executive Summary GSDX is a graphics renderer plugin for the PCSX2 emulator, enabling PCs to render PlayStation 2 (PS2) graphics via modern APIs (Direct3D 11/12, OpenGL, Vulkan). Originally developed by Gabest (hence "GS" for Graphics Synthesizer + "DX" for DirectX), it has evolved from a basic Direct3D 9 proof-of-concept into the most sophisticated PS2 GPU emulation layer available.
