Guide to graphics performance in Unreal Engine

Companion text version of the Unreal Engine Game Optimization talk I presented during JetBrains GameDev Days 2022.

Debugging GPU crashes on PC can be challenging. We'll go over best practices and the tools available in Unreal Engine to debug such crashes. This includes a new GPU breadcrumbs system, which provides the equivalent of a GPU “callstack.” Additionally, we'll examine case studies and discuss classification tools we use internally to automate crash grouping in Jira. This approach allows us to focus on the most critical crashes, eliminating the need for manual digging through logs.

This is a collection of Ari's personal Unreal Engine learnings, notes, cheat sheets and more which he's made public.

Everyone on your team should be able to gauge the performance impact of their work. In this session, Unreal Engine Evangelist Ari Arnbjörnsson uses the new built-in tools of Unreal Engine 5 to find nasty performance traps and bugs he deliberately planted in his demo project before the presentation.

Not UE-specific, but a very nice profiling tool that can be used with UE for more precise stats.
