Impressions after 12.1 release ? For me nothing seems to have improved much so far, first crash after 45 mins (total) of gameplay in Moria/Galtrev area with 2 different toons...graphic settings as suggested above..
I've been busy updating material on lotro-wiki.com and just now finished patching.
Assuming that there was not much changed between the end of the Beta and today, there is/was nothing exciting for the Mac Client.
45 -60 minutes is what I have been seeing consistently since the middle of the HD beta. Things seem to be much more "stable" in West Rohan than in East Rohan.
"Stable" refers to everything but the 45-60 minute situation. There is definitely a timer-runout triggering my crashes -- I see them in the dumps all the time. Even when I'm just sitting there reading/copying stuff.
