LZDoom

LZDoom is a 360-view Doom source port based on GZDoom, developed by Diego Antonio de Membiela Sánchez. It is intended for lower-end computers and therefore uses the older OpenGL 2.1 renderer, allowing for greater compatibility with older graphics cards.

The port maintains GZDoom features such as ACS, 3D floors, slopers, reflective floors, dynamic lighting, etc.
