[0.91] It's nothing!

Bugzilla-like programs often collect tons of data that often can not be reproduced by even the built-in debugging features of Windows (I.E. Dr. Watson).

However, I do warn the average user with a lower end system. User beware! MapleStory 0.91 will contain debugging level code that not only will make the game run slower (unrelated to CPU and lag time) but also make the game more traceable by the developers for certain systems.

There is one major problem however with this system.

Sending data is voluntary.

Most users tend to click the Cancel or Ignore button of these programs.

Not much of a performance problem, mainly because most other language such as Java/ C# already have build-in unhandled exception catching and debug information.
Those language are still as good as C++.
