This is Crysis running with SwiftShader, a Direct3D 9 and OpenGL CPU/software renderer. Crysis is running in Dirct3D 9 at the lowest settings in 720p resolution. The framerate is just barely playable. This was rendered with a AMD Ryzen 2700x. The encoding of the screen capture was done with the GPU as to not steal CPU cycles from SwiftShader.
