A simulator is disclosed. A cockpit model comprising a plurality of cockpit model parts that collectively correspond to a simulated cockpit in a simulated vehicle is maintained. For each frame of a plurality of frames, a plurality of cockpit view frustums are determined, each cockpit view frustum corresponding to a different cockpit view of a plurality of cockpit views of the simulated cockpit. Shared cockpit scene information comprising a set of cockpit model parts that are within any of the plurality of cockpit views is generated based on the plurality of cockpit view frustums. A processing device submits to a graphics processing unit (GPU) the shared cockpit scene information and GPU instructions that direct the GPU to generate a plurality of cockpit view images that correspond to the plurality of cockpit views from the shared cockpit scene information. The GPU generates the plurality of cockpit view images.
