In the last months I have tested the animation capabilities of v2.2 and want to share some results:
Because of OIDN and persistent PhotonGI cache it is possible to render 3k frames in less than 5 min on a Windows PC with RTX 2070 + GTX 1060 (PathOCL).
The new hybrid engine lets you add caustics rendered super fast on CPU with no time penalty.
Big thanks to all the devs for their great work
