@lsalazarm99 No, that's something the team has been working on very recently. Not all changes or new features make it into the live game right away.

A small correction here: The optimizations mentioned in the article are about improving performance and loading times at the cost of disk space.
Apologies for any confusion, and a thank you to @simplygon once more for your support in this!
