I recognize some of the problems the others are facing. Maps take rather long to load, but the most annoying thing are the really long loading times for mobs, npcs, minions, mounts, player models and sound effects. With group events none of the player characters will load, not even when the event finished. I only see the 'placeholder' model.Strange thing is the skimmer mount loads immediately, but the others all take a while. My character sinks into the ground and the camera will stay in place.Sound effects are often completely gone too.Walking into an unknown area (I'm a pretty new player so haven't discovered everything yet XD) is impossible: It seems the area is clear and I walk in when suddenly my healthbar lowers and surrounded by mobs. Have died several time because of this. Highest fps was 40(rare). Sometimes drops to 8. Often around 20. Graphics are all on low, render sampling on native.After a few hours of playing it runs a bit better for a few minutes, then it runs really smooth and even loads mounts, mobs, npcs and sounds fast. Good things are: my mac is really silent and doesn't vent loudly anymore. It doesn't get super hot immediately and crashes seemed to have disappeared.It's playable but the 32-bit was much smoother and i could do group events easily. Just hoping all the problems will be fixed by the macteam so that it runs like the 32-bit did.
