» Refined profiling for mobile
Unity 4’s Profiler now reports on GPU usage for games running on Android devices with Tegra chipsets, so you can zero in on and adjust performance bottlenecks for gameplay on the move. The Unity Profiler reports how much time is spent in the various areas of your game. Play your game in the Editor with Profiling on, and capture performance data for CPU and GPU usage, rendering, physics, audio and memory.
» DirectX 11 rendering
Higher visual fidelity and faster rendering times for your professional PC games: Unity 4 now supports the Windows DirectX 11 graphics API. Improve performance with compute shaders, which give the ability to use GPU as a parallel CPU. Utilize more complex shaders with shader model 5.0, and add richer details to your game worlds’ models and environments with tessellation.
» More detail and control with your lightmapped scenes
Unity 4's iterative lightmap baking gives you complete control of your lightmapping workflow. With the option to "bake selected", you spend time baking only the parts of the scene you are actively working on. Coupled with new updates, such as the use of normalmaps when lightmapping, and lower memory requirements for the bake process, it has never been faster or easier to add detail and nuance to your lightmapped scenes. Scenes with both normalmaps and dual lightmapping appear more polished, smoothing the visual transition between objects at far and near distances.
» Skinned mesh instancing
Efficiently create your own crowd rendering system. Unity 4 gives you script access to the output from a skinned mesh renderer, so you can precompute animated poses, or cheaply render multiple instances of a mesh in the same pose.
» New Text Rendering Backend
Unity 4 now features dynamic fonts for mobile games. Render asian characters at any resolution, and use HTML-like markup to control font sizes, weights and typeface selection.
