Asset Manager in Unreal Engine lets you asynchronous load game content with soft references and even partially load assets.

Unreal Engine is a complicated piece of software, throughout the course you will gain a solid understanding of how the many CPU threads and GPU operate and how it all ties together to create a fully rendered frame. We’ll dive deep into the process of profiling, finding bottlenecks and discovering opportunities to improve the overall performance.

In this talk, Tanglewood Games will dive into the Game Thread in UE5 and explore how we can profile and optimize this.

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.

When you are dealing with assets, it’s easy for dependency chains to get out of hand. And sadly, you don't always notice them until they become a big problem. In this talk aimed at programmers and Blueprinters, Lucid Games’ Studio Technical Director Mark Craig shares tricks developed at the company for spotting, analyzing, and fixing such problems—so you don't make the same mistakes.

A weirdly broken blog post, but contains enough info to setup a way to split the game data into different files for optimized updates.

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

As you continue to push the boundaries of the next-gen graphics features of UE5, you may find yourself in unexplored territory with an overloaded backpack and nary a trail marker in sight. How do you find your way back to the trail? Should you be changing how you pack your bag for the trek? Was there anything you could have done before you set out to make things easier? Let’s dive deeper into debugging Nanite, Lumen, and VSM performance issues so that we can get back on to the trail. Then, we’ll learn more about managing the memory of our new graphics features, including how we can leverage virtual texturing to make sure our pack is properly balanced. Along the way we’ll learn about what we can do to make sure we’re staying on track far into the future.

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

Garbage Collection (GC for short) is a very basic feature that is present not only in many Game Engines like Unreal and Unity, but even some programming languages like C# come with it built in.

Dr Elliot has some C++ tutorials on constexpr, networking and low-level allocations.

Faced with the challenge of building massive environments from over 60,000 mesh components, including fields of real-time simulated debris, the engineering team at Creative Assembly needed to find a way to reduce level streaming costs and optimize rendering of unique instances. In this talk, Grant Johnson, Senior Graphics and Engine Programmer at Creative Assembly, will look back at the problems the team faced building these environments in a multiplayer first-person shooter set in space, as well as diving into their solution (dubbed ‘Chocolate Rendering’): a modern geometry renderer injected directly into the engine. This talk will highlight how to reduce level streaming costs and increase unique instance counts while still using the foundations of Unreal Engine. Grant will also specify the team's approach to minimise engine modifications and ensure seamless future integrations.

This is part 1 of the "How Unreal Renders a Frame" series, you can access part 2 and part 3 as well. I was looking around the Unreal source the other day and inspired by some excellent breakdowns of how popular games render a frame, I thought to try something similar with it as well,…

Ari Arnbjörnsson: "I’ll be speaking at Unreal Fest Seattle! Come watch my talk where I myth-bust “best practices” in Unreal Engine: “Are Ticks really that problematic? Should you avoid using the Construction Script? Is the ChildActorComponent truly cursed? Should you never use Cast? You've probably heard many of these so-called "best practices”. Let's put them to the test and find out which ones are true and which ones are bust!”"

Unreal Engine can auto-detect ‘optimal’ (graphical) settings per player based on a quick CPU and GPU benchmark. The functions are available in Blueprint to hook up into your game’s options menu. Behind the scenes, the...
