Unity's HDRP (High Definition Render Pipeline) is a new set of tools that unlock the power of modern graphic cards and allow achieving better visuals. We invested a lot of work to convert all graphical assets to the new system during the recent months. However, it is only the first step of the migration process. We decided to release the current progress, although we have not reached the full power of HDRP yet. There are many parameters that still need to be tuned for the best visuals and performance. We plan to introduce all the advantages of HDRP step by step in future updates.
