No doubt you have heard players complain about their settings in the normal game being changed to the settings of the PBE (Oh, and if you have used the PBE, check your network and gameplay settings. You will thank me later.).

Default network buffering on the PBE is maximum because of the loosened MM settings. I found this out after my shots would visibly hit someone but deal no damage, people started teleporting around, among other weird network jank. One you have probably heard about its enabling stats in the top right.

While these are easy to fix, they are not always obvious and could easily go unnoticed (but as is the case with higher buffering, drastically harm gameplay). Thusly, they should not transfer automatically between the two. The first time the PBE is opened by a user, yes (so sensitivity and such are the same) but after that they should be treated as separate configurations.
