Qbism has more modern features like a distinctly odd but high-performance implementation of colored lighting and Gouraud shaded monsters, but these can be turned off in the console. Qbism Super8 and Mark V WinQuake are excellent software rendered ports compatible with modern Quake mods. But I'm not interested in all these dynamic lights and animation smoothing stuff, and honestly, I'm not 100% which source ports will actually let you disable that kind of stuff. I want to maintain the closest I can to the original software renderer, and the only thing I want to add is support for a widescreen high-res display, and maybe some limit lifting in case I want to play some custom maps. I'm really looking for a 'Chocolate Quake' (or a Crispy Quake). I was looking around for a better source port, but there's quite a large list of them, and to compound matters, the most popular ones are touting features I don't really want. I was playing some classic Quake this weekend, and I came to realize that the only source port I have for it is the GLQuake that Id released.
