Sentry helped Amanotes identify the root cause of their Unity game's Application Not Responding (ANR) errors, which were not apparent through traditional profiling tools. By analyzing Sentry data, they discovered that scene loading transactions and heavy methods were causing delays, particularly when initialized too early during startup. Optimizing these areas led to a significant reduction in ANR rates by 50%, from 0.98% to 0.46%. The key improvements included reducing scenes' loading time, minimizing dependencies, preloading assets smartly, and deferring instantiation. By using Sentry for Unity, Amanotes was able to pinpoint invisible performance issues and optimize their game's startup and scene loading processes, resulting in a better user experience.
