Here you can see examples of mutipass shader use. Multipass allows to create intricate per-pixel effects such as specular highlight or even texture compression. Because FreshEngine is symetrical, you can use multipass shaders on skinmeshes, non-skinned objects, dynamic or static geometry.

These are examples of full-screen antialiasing (FSAA) on FreshEngine PSP. As you can see, the image quality is greatly improved when fsaa is turned on, with a fixed cost of about 1.75 miliseconds. The cost is mainly due to the buffer copying, as opposed to simple buffer swapping. Buffer copying provides other effects for free such as tone mapping and is mandatory for post effects anyway. So all in all, it is worth turning on FSAA in your projects.
