In my case all of this is happening in singleplayer (unmodded) testlive.
In addition to the previously reported performance issues when loading into the game (see here for an example), I am experiencing new performance issues with the map screen.
Specifically - when I press the key to open the map screen, there is a delay (a couple of seconds) while the game ‘decides whether it feels like it’ - this is not present in even heavily modded games on live branch.
I’ve also just had the testlive client crash on me again (after only around half an hour of testing) - normally I get around 6 hours before I have to start risking crashes and have to think about re-booting.
As noted elsewhere, none of these issues are major in themselves, but they appear to indicate a significant degradation in performance between the live version and the testlive version. (Crashes may not be an issue, since testlive may be unstable because it is unfinished, but noticeably worse performance seems to indicate a problem.) My machine is within the recommended specs for the game and I am having problems with basic elements of performance, which suggests the problem may get far worse for those on lower spec machines.
I hope Funcom will take a serious look at the way that the current testlive patch is performing and hopefully find a way to bring performance back up to similar levels to live branch.
Edit: This thread contains some further information that looks (to my untrained eye) like it may be performance related as well, also on testlive. Maybe @Papatango0269’s findings could provide the team some clues as to what’s going on:
