How to Optimize Unity Mobile Game Performance: A Real-World Case Study

Mobile game performance optimization is rarely about fixing just one issue. Low FPS, frame-time spikes, excessive CPU usage, and GPU bottlenecks can all contribute to a poor gameplay experience.

But where should you start when a Unity mobile game struggles to maintain a stable frame rate?

In this case study, we'll walk through a real Unity 6 mobile game optimization process using GameOptim GOT Online. The test covers performance profiling, CPU and GPU analysis, memory investigation, and several practical optimization techniques.

The results were significant:

  • Average FPS: Improved from 16.60 to 29.87 (+79.9%)
  • Frames exceeding 40ms: Reduced from 94.51% to 0.19%

Let's take a closer look at how the performance issues were investigated and optimized.
