Lockheed Martin Prepar3D: What are the system requirements?

Prepar3D v6 requires approximately 85 GB storage, 32 GB RAM or more for optimal performance, 8 GB or more VRAM, and a DX12-capable GPU with 64-bit architecture. Detailed scenery and aircraft add-ons can significantly increase storage and performance requirements.

Source
Lockheed Martin Prepar3D: Can I create custom training scenarios?

Yes. Prepar3D includes SimDirector, a scenario generation tool that allows users to create training scenarios across aviation, maritime, and ground domains. Users can place world objects, define scenario logic, create missions, and provide instruction sessions, making it suitable for cockpit training, flight planning, and emergency response preparation.
