I was the content owner for most of the scalability systems for Halo Infinite.
The goal was to create data driven systems that allowed the art leads/content teams to be able to fine tune visuals vs performance/memory to create something that looks good at all supported hardware specs.
I created specs, planning, documenting, testing and giving feedback as well as tuning the majority of the systems.
This was something that a lot of people was involved in creating and tuning. Both from engineering and content teams.
