Major improvements are an up to 10x higher throughput for scenario files that are sent from a session host to the clients via typical DSL connections, making “join in progress” cases and last minute changes of multiplayer scenario files a lot more practical. All 3D characters will now use normal and specular maps, and therefore blend with the surrounding environment much better. An improved lighting model will now also bring out the normal maps when there’s only indirect light on the surface.
Also, the installer will update the security settings for the map folder, so that an installation as administrator is no longer necessary.
Beyond that, a truckload of bug fixes.
