Unreal Engine Game Optimization

Lighting and Shadowing
Lighting and shadowing play a pivotal role in creating immersive environments. Unreal Engine provides a host of tools to optimize lighting and shadowing effects, such as dynamic shadow resolution adjustment, precomputed lighting, and efficient light-baking solutions. These tools ensure that games maintain visual quality while maximizing performance.

Miscellaneous Effects
Unreal Engine also caters to optimizing various mizcellaneous effects that enhance the game's aesthetics. Tools are available for optimizing particle systems, post-processing effects, and material shaders, enabling developers to strike the perfect balance between visual impact and performance efficiency.

When it comes to your Unreal Engine game, blind optimization should be avoided. Identifying the bottleneck in your project is essential to achieve meaningful performance gains effectively. With the Game Thread, Render Thread, and GPU operating asynchronously, understanding which component is causing performance limitations is crucial.

Finding the Bottleneck
Measuring and identifying the bottleneck is a crucial first step. Unreal Engine provides tools to assist in this task. Unreal Insights, a flagship profiling tool, offers detailed insights into various aspects of your game's performance, including CPU, GPU, memory, file loading, and threading. By using commands like "stat unitgraph" and "stat detailed," you can gather valuable information to identify the performance bottleneck.

Unreal Insights
Unreal Insights is a powerful profiling tool available in Unreal Engine 4 and continuously improving in version 5.0. It provides advanced memory profiling and offers detailed insights into frame timings, CPU/GPU usage, memory consumption, file loading, and threading. This tool allows you to drill down into specific frames or sessions, enabling deep analysis of performance bottlenecks.

Optimizing Memory & Loading
Unreal Insights provides various commands and features to assist in memory analysis, such as "memreport -full" and "loadtimes.dumpreport." These tools provide detailed reports on memory usage and loading times, helping you identify areas for optimization and improve overall performance.

Culling
Culling is a vital technique for optimizing scene rendering. Unreal Engine offers powerful culling tools that determine which objects and assets are visible to the camera and dynamically cull out those that are not. This reduces unnecessary rendering calculations, leading to improved performance and frame rates.

Defeaturing
Defeaturing is an optimization technique that simplifies complex geometry by removing unnecessary details that may not impact gameplay significantly. Unreal Engine provides tools to automatically defeaturing geometry, reducing the computational load and improving performance without compromizing visual fidelity.

Utilising Unreal Insights Tips
To maximize the effectiveness of Unreal Insights, consider the following tips:

• Run commands during a session to compare performance, such as using "r.ScreenPercentage 20" to reduce rendering resolution or "Pause" to freeze the Game Thread.
• Customize the profiling categories to focus on the most relevant aspects of your optimization goals, reducing unnecessary overhead.
• Utilise custom bookmarks in Unreal Insights to mark specific gameplay contexts and easily revisit them for analysis and comparison.
