But the explanation just does not satisfy me.

I mean, world building is an expensive but actually pretty simple, predictable operation. If they want to see how it performs on slower computer they don't need to get telemetry, just actually run it on slower hardware.

As if all problems are reproducable at will on all the different set of software / hardware out there ...

In theory it ought to be, but since drivers are generally closed source we actually have to test on everything.

What I meant is that you don't know the problem until you had it, out of the millions of players you need feedback that something is not working properly, reports / telemetry is a must have. Most serious online games have such mechanism.
