The goal of this challenge is to create a tutorial that explains how to optimize the performance of a game. The tutorial should be easy to understand and approachable for all skill levels. Describe what factors affect the performance, and how to optimize these factors.
Some topics to consider for the tutorial are listed below.
Explain how to use the Performance Panel as well as the Play-Mode Profiler to analyze the performance of a game. Describe how to identify bottlenecks (game, render, networking, GPU). Cover testing with single player, multi player, and live server modes. Mention other helpful tools such as the FPS Tracker and Performance Mapper Tool in CC.
The player count dramatically affects the performance of a game. Explain how such things as player attachments, and object and camera collisions can impact the performance, and how to optimize things.
Explain how Core contexts affect the performance of a game, and how to use contexts properly to optimize performance. The most common mistakes are using the wrong contexts, and using more Networked Contexts than is actually necessary.
Describe how to optimize the models in a game with such techniques as limiting the object count, and using Merged Models.
VFX and SFX can also affect the performance of a game. Spawning a lot of FX can get very expensive quickly depending on the particle size and density. Make sure effects are in the proper Core context, and have a lifespan set. Adjust the draw distance for further optimization.
Lights & Shadows
Too many lights, overlapping lights, and lights that cast shadows can significantly impact the performance. Optimization techniques include using less lights, less overlapping, and adjusting the settings and draw distance.
Too many decals can affect the performance. Use fewer decals and adjust the draw distance settings to improve performance.
Some scripts and objects may not properly be destroyed if referring to equipment, user data, or other items in the game. See Cleaning Up Event Listeners.
There is a high cost associated with animating objects that have collision enabled. If possible, disable collisions on anything that is animated.
Large triggers that move can also impact performance significantly.
Describe optimization techniques for terrain and foliage within a game. Cover the various performance related settings such as LOD and draw distance.
Include any other other topics that affect performance (outline object, transparency, custom materials, etc)
