## Warmup cost

This sky type requires heavy precomputation to be rendered. Because of this, the first few frames (depending on the *Number of bounces* parameter) are going to take much longer. This needs to be taken into consideration when switching from another sky type to the Physically Based Sky for example as it might produce a noticeable drop in framerate.
