Yep, that's my experience on a high end MacBook Pro as well. It seems to do some main-thread-blocking texture/model loading or shader compilation that results in the entire game freezing for as short as a split second, but sometimes as long as up to several seconds. It makes for a very bad experience (sometimes unplayable for things like jumping puzzles, especially when other players are around) and is my number one complaint with the current state of the game. It's nice to see they're making progress on other issues but this one should be a high priority.Appreciate the affirmation. Your description is very similar to what I'm experiencing with the split second freezes (what i call jittery). @DrMORO.4627 said: Welcome back to GW2! Unfortunately, your timing of return was not opportune, as what you are experiencing (or not...) is the sad reality of GW2 on Mac at this moment.This tread has a TON of info on others' situations, obviously most all negative as those would post here, while looking for answers.The one's with working & playable GW2, they most likely wouldn't post here.There are a few posts on Hackintosh users here as well, and some working, some not so lucky. And seems one issue is with the latest Mac OS X 10.13 High Sierra, and some including me are actually holding off upgrading to High Sierra just because of this problem.Others, high I/O disk activity, and obviously graphic issues, possibly caused by different configurations of everyone's Mac, even thought it is not an infinite variety like in PC. We are all mostly just waiting for THE people 'high up there', to identify and to fix problems within the Mac 64-bit GW2 app to an acceptable level, as soon as possible, and then release it for us Mac users to play GW2 happily. No ETA announced yet, unfortunately, so our waiting continues... (beachball rotates forever here) I was looking forward to giving GW2 another good effort with a few other folks, so maybe I'll tinker around a bit more. I'm locked into the Apple environment for a bit - even with the hackintosh - and after reading a bit it doesn't sound like upgrading to a RX580 will make much difference. I overclocked the CPU to 4.0ghz and GPU about 15% (both temporarily) and it made little difference; adding around 4-8 fps all around. FWIW, I played for 2 days prior to upgrading to High Sierra from Sierra on Monday and don't notice any difference in performance between the two. Appreciate all the feedback.
