Ensure you click the link labeled specifically for 64-bit (x64) . The file name is typically libEGL.dll and libGLESv2.dll (SwiftShader 3.0 uses these names to hook into DirectX via translation layers).

SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and DirectX graphics APIs. It is designed to render 3D graphics on systems that do not have dedicated graphics hardware or whose graphics hardware is incompatible with certain applications.

The "SwiftShader 3.0 DLL" refers specifically to a version of this software often circulated to help run games and 3D applications on older or low-end computers.

Older games (like Age of Mythology, GTA: San Andreas, or World of Warcraft Classic) require "Hardware Transform and Lighting." If your integrated GPU (like Intel GMA) doesn't support it, you get a black screen. SwiftShader 3.0 emulates TnL perfectly.
