DirectQ is a port of Quake to native Direct3D 9. The primary focus is on replicating the original look and feel of software Quake, but it also has significant usability and rendering improvements. The old Quake engine was hardware accelerated using OpenGL. However, it was written in the infancy of OpenGL (at a time when even texture objects were only available as an extension), and several of the rendering methods used back then had some room for improvement. Furthermore, it is known to cause issues with some manufacturer's OpenGL drivers. Rather than hacking around at the existing codebase, a clean start was chosen with Direct3D that could run on a modern laptop. As part of the port the codebase was also changed from C to C++. |
