REAC 2024 DAY 2 Optimizing the UI's CPU bound frame rate in Call of Duty
发布人
https://www.youtube.com/watch?v=iDhBz_PovwU This talk takes a deep dive into the system that drives the user interface and HUD of Call of Duty. Over the years the Call of Duty UI performance had atrophied and gotten into a state where it was impacting the frame rate of the entire game - and even risking the launch of the title. This is the story of the battle that was fought to both reclaim the lost knowledge of our UI engine while getting the performance back to a suitable state for the release of Call of Duty. Speaker: Simon Eschbach has somehow shipped 10 games while ending up in the same place every time: Detangling, debugging and optimizing long neglected user interface systems. His work started 20 years ago on the original BioShock games and ended up spanning several genres to finally end up back in the frame rate critical FPS space on Call of Duty. After being on the CPU performance critical path for the last three Call of Duty titles, Simon is ready to share his war stories from the trenches.
