[ Thanks to Michael Larabel for this link. ]

"The graphics improvements in this game update include tangent light space vector normalization for per-pixel mesh rendering, GLSL program management, GLSL normal/specular mapping for dynamic lighting, GLSL specular lighting, new water shaders, distortion shaders to basic water, faster image filtering, and new glass effects with a semi-true reflection. There are also performance increases in this release through calculating bounding boxes at load file along, occlusion culling of entities, and moving the vertex lerping inside of a texture-mapping loop."
