Client Crash Rate

What exactly does the Client Crash Rate analytic represent? Because I can’t relate anything to it, I have a game that’s optimized but still has a 3% crash rate, then a game with worse optimization and a lower crash rate.

According to my knowledge , correct me if I am wrong . The crash rate does not always depend on the optimization , however memory leaks play a major role . As discused in dev fourm , the client crash rate can also be increase if a player directly closes roblox either by hitting Alt+F4 on PC or by closing the app on their phone. Also your game could be well optimized for mid range , or even low range , but still there could be someone with very low end device , which could not process your game . Tip Press F9 and see the errors and memory usage to futher dig down the problem


crash rate for PC is higher than mobile???

Many people just close roblox directly , without going to the tedious process , of first leaving the game and then closing roblox , hope this helps :))

Client Crash Rate is basically the percentage of sessions where the Roblox client shuts down in a way that is not considered a normal exit.

It does not only reflect issues in your code or performance it also includes cases where the client itself encounters an error the player force closes the app, the device runs out of memory or the hardware just cannot handle the load. That is why you can see a well optimized game still reporting a higher crash rate compared to something less optimized.


This page should help you understand and learn more about it!!


The number is more about how often players end up leaving because the client did not exit cleanly and less about being a direct score of how good your optimization is… Things like device variety, memory usage patterns and even how players choose to leave can all influence it! Like @Raghavbhalla907 said mobile players AND pc players can close Roblox without using the leave button… which the Crash Rate detects as a crash!

Hope this helps you!!
