Best Ways to Improve Performance of Unity 3D Game
6 min read

It is relatively easy to make a game these days. But, it can be difficult to create a game that looks, feels, and moves fluidly. It can be frustrating to see games that don't perform well or lag after a long time of development.

Unity engine is becoming more popular because of its intuitive interface, wide variety of tools, and powerful features. It can be difficult to develop high-performance games, especially for complex and large games. These are some tips and tricks that will help you improve the performance of your Unity 3D game engine.

Ways to Improve Performance of Unity 3D Game

Optimizing Game Scenes

Unity makes it easy to optimize game scenes for high performance. You can achieve this by reducing the number of objects, using optimized textures, and models, and using a Level of Detail system (LOD). This allows you to control the level of detail of objects when they are further away from your camera.

Also, it is important to make sure your scene is well-constructed and that your objects are correctly sized and positioned. Scene optimization also involves reducing the number of dynamic objects to make it more efficient. Instead, use static objects whenever you can. Because rendering is more efficient, this is important.

It is also important to optimize the scene for occlusion. Also, ensure that objects are properly culled to reduce the number of objects rendered per second. These tips will help you optimize your game scene for smooth operation on different devices.

Unity Profiler

Unity Profiler can be used to optimize your game and improve its performance. This tool gives you detailed information about CPU and GPU usage, memory use, and other factors that can be used to optimize your code.

Open the Unity Profiler window and run your game. This will display a breakdown of the resources used. This information can help you reduce the number of resources used, optimize your code, and minimize calls to the non-essential functions.

Unity Profiler also profiles different platforms and devices, so you can ensure that your game runs well on all systems. This tool can help you improve your game's performance, resulting in a more enjoyable user experience.

Use Lightmap UVs

The Lightmap UVs are crucial in optimizing the performance of Unity games. These precalculated maps store shadow and lighting information. This greatly improves performance as it reduces the need for real-time lighting calculations. Lightmap UVs can be used to utilize baked lighting which is more efficient than real-time lighting.

Lightmap UVs require that the UVs of objects be properly unwrapped. After that, you must bake the lighting information into the lightmap. The lightmap can then be used to light objects in the game. This greatly reduces the effect of lighting on performance. The game's appearance can also be enhanced by using Lightmap UVs.

Lightmap UVs can be used to ensure your game runs smoothly on many devices. They also create high-quality shadows and lighting without sacrificing performance.

 Avoid unnecessary calls

Unity's performance can be optimized by avoiding unnecessary function calls. This will ensure smooth gameplay. It's important to avoid overusing functions in your code. This can cause the game to slow down and cause stuttering.

Cache variables are a way to reduce the number of function calls. They store the result of a function and allow you to reuse it rather than calling it again. This can dramatically improve performance by reducing the number of function calls.

A co-routine can be used to reduce the frequency of function calls by breaking up processing into smaller chunks that are executed over multiple frames.

It is important to avoid calling functions that return the exact same result. This can be seen when you repeatedly call Get Component to access the same component. It is better to store the reference in a variable than repeatedly call the function.

These techniques can dramatically reduce unnecessary calls in your game. This will result in better performance and a better user experience.

Use a Job System

Unity's Job System is an efficient optimization tool. Multi-threading is used to improve unity game engine performance by simultaneously executing multiple tasks. The system assigns work and increases performance to worker threads. This reduces the load on the main thread, particularly for games that require heavy computations like AI or physics. It allows you to create simple parallel jobs that can be scheduled, synced, and combined for optimization.

It also offers automatic memory management which makes it easier to manage memory when working with worker threads. Some tasks may not be possible to parallelize, and others will need to be re-run. Analyze your game to identify tasks that could be parallelized. Unity Job System is a powerful tool that can dramatically improve performance. It allows for smoother gameplay and better use of resources.

These tips will help you optimize your games' performance and grow them into a cohesive game engine. You should test your games regularly to identify and fix performance issues and optimize your code and assets as your game evolves.

Conclusion:

There are many ways you can improve the performance of your game, not just one style or genre. However,  this overview of common performance  will be helpful regardless of what type of game you are making. If you have any quires about Unity 3D , Glownight Games will be helpful to you.
