Quick answer: Loading times affect retention. Tracking P50 / P99 loading time per asset class surfaces regressions; players drop off if loads are slow.
Players quit on slow loads. Track loading times; act on them.
Per-asset class
Texture, mesh, audio, scene. Each tracked separately; bottleneck visible.
Per-platform
Mobile vs console vs PC. Per-platform percentile; surfaces platform-specific regressions.
Track over releases
Per-build percentile. Spike on a release = regression; investigate.
Set budget per scene
Loading screen budget; over = action required.
“Loading time is gameplay friction. Track it.”
Loading time is one of the easiest metrics to track; one of the hardest to fix retroactively. Track early.
