Celer

This mod improves frame rate, mainly by adding portals and occluders.

It does NOT alter visual quality. No textures are changed.

Occluders are surfaces that prevent rendering the objects they hide.
Portals are areas that influence objects visibility status, depending if you're inside or not.

Additionally, it features an improved occlusion manager and faster portals processing.
