reQuiem is a custom OpenGL Quake engine for Windows and Linux. It's designed for maximum compatibility with all things Quake - past, present and future. It's fast, reliable, and easy to configure. In short: it fixes what was broken, improves what needed improving, and leaves the rest alone. It was developed by jdhack.
If a skybox is set and any fog value (eg fog 0.1), the fog will appear solid before the skybox. This is technically correct (skybox is far far away so there will be a lot of fog in front of it) but mappers don't want that. See http://www.celephais.net/board/view_thread.php?id=60979&start=134
