While Chasm may look more like Quake engine game, it is actually closer to Doom/Duke.

It has slopes and 3d models, as well as interactive 3D environment and loads of cool effects, but it can only doo 1 floor with no RoR whatsoever.

It was being able to run at 486 at decent speed (where Quake and Descent could barely do 15 fps), due to it using some sort of approximation algorithm for rendering world geometry. (also world is not true 3D and can not render looking up/down properly, same as Doom and Duke), Not noticable on low resolutions, it becomes a bit visible at 640x480 (highest the game can go on my Dosbox setup). You can see the wall and objects wobbling a bit if you look down and rotate.
