A look back at the Prism3D Engine: The backbone of niche simulation.

The is the proprietary, in-house game engine developed by SCS Software that serves as the foundation for nearly all of their simulation titles . Written entirely in C++ , Prism3D has evolved over more than two decades from powering early hunting games to sustaining massive open-world simulation giants like Euro Truck Simulator 2 (ETS2) and American Truck Simulator (ATS).

First, the visual component of Prism3D is known internally as the . Dagor is a proprietary rendering middleware that supports a wide range of hardware, from high-end PCs to mobile devices and even PlayStation Vita. Its hallmark is the ability to render extraordinarily long draw distances—essential for aerial combat in War Thunder —without compromising performance. Dagor achieves this through a highly optimized level-of-detail (LOD) system and a deferred rendering pipeline that efficiently handles hundreds of dynamic light sources, from muzzle flashes to exploding fuel depots.
