on my new iMac with i7 and 16BG RAM and a 1TB Fusion Drive on Mountain Lion the Lotro client constantly crashes when I move from one area to another. e.g. after travelling from Bree to Moria or entering a seperate zone like the auctioneer hall in Stangard. It crashes sometimes but not always at that second when the progress bar appears to load the new area. So this is not reproducible and the quote might be 40 to 50% when loading a new area.
Next thing is i have really bad graphics when entering for example Draigoch. I just see fractions of the landscape, i couldnt make one step because i dont see if there's a hole or a stone or a normal path in front of me.
And when i fight with my Runekeeper i see yellow squares around the mob after hitting him. This makes me nuts.
Outside the landscape is fine but also here i have sometimes the yellow squares bug.
Maybe someone can help me or tell me that the client is the problem, not my imac or some settings.
(ps: sry for my bad english, im from the EU)
