Why is the DCS terrain not as detailed as other games like Battlefield II and Armed Assault??
The initial release of DCS (the Black Shark module) uses a modified version of The Fighter Collection Simulation Engine (TFCSE). This is the same engine we used for earlier entertainment and military-grade simulation products. This engine provides worlds that are much, much larger and much greater rendering distances. As such, object density cannot be as high or suffer significant frame rate slow-downs. We believe the current DCS engine provides a good balance of large and diverse worlds with detailed graphics. As we develop our new DCS engine, we will increase terrain detail even further.
