Planning for Top Performance: Optimization Techniques
The goal of this workshop is to present participants with proven workflows for overcoming the performance issues in games. As participants work their way through the activities, they will be presented with different projects that have varying optimization scenarios that they will have to investigate and fix.
Each project focuses on a specific area of common optimization issues like graphics optimization, script optimization, memory allocation and platform limitations.
Level: Intermediate
Prerequisites: Prior experience with the Unity editor.
Duration: 7-8 hours
Class size: 15 people
Trainer: Unity Certified Instructor
