Rumbleverse is a 40-player battle royale game built in Unreal Engine 4–but using a general-purpose engine doesn't stop Iron Galaxy Studios from making engine-level optimizations to push the game to look the best it can be, while running at 60 FPS across console generations.

Jon Moore, the game's lead rendering engineer, will share many optimizations made throughout the game's development and how optimization opportunities arise when leveraging a specific game's constraints. Ultimately, choice of engine doesn't affect optimization potential.


Attendees will learn about optimization strategies to best fit technology to the game and details of specific GPU and CPU performance optimizations made for Rumbleverse.

Intended Audience

This is for any engineer embarking to push performance as they tackle bigger and more ambitious projects, and will share a number of optimizations that fit a range of experience levels from fundamental to advanced.
