The 3D client technology is built for Windows PCs and browsers and is available on iOS, Xbox 360, and PlayStation 3 via a network API.

BigWorld Technology also integrates various third-party plugins such as Umbra (occlusion culling), Scaleform (user interface creation), Speedtree (foliage), and Vivox (VOIP).

BigWorld Server supports dynamic load balancing, a feature that automatically and dynamically spreads user load across multiple cell apps on the same game server, allowing for large numbers of concurrent users to inhabit the same game space.

BigWorld successfully demonstrated the linear scalability of its load-balancing technology by dynamically balancing 100,000 entities across various cell apps on a single server.
