With the promises of infinite system memory and disk bandwidth devoured by 4k assets, it is once again beneficial to balance performance against utility and memory footprint. Occasionally, however, by taking advantage of ubiquitous hardware features and paying close attention to your data bit by bit, gains can be made on both fronts. This session is a highly technical deep dive into the process of optimizing the high-accuracy model collision in Call of Duty: Black Ops Cold War to reduce memory footprint to less than one-fifth it's size while simultaneously conferring a two-fold speed increasing.
Attendees should leave this talk with ideas for optimizing their triangular collision representations as well as a better understanding in general of making good use of every available bit with respect to alignment and hardware constraints.
Collision programmers are the primary audience with backend engineers also obtaining some useful information in terms of in-memory database representation. Only a basic understanding of linear algebra, bit manipulation, and SIMD code is required.
