Same here. My main is in Bjora Marches and the client crashes in less than 10 seconds since the character is visible.It's really sad that such a bugged version can get released. They don't even test it anymore on the Mac.

I've recently noticed that Vertical Sync, with High Sierra, under certain conditions, drops the frame rate significantly, from ~25 to less than 20. The area where I find it more noticeable is in Verdant Brink. Not only it drops the frame rate, it seems to do so by wasting CPU cycles: fans spin up, and there's a general slugginess and unresponsiveness. Pretty sure this was not happening with Sierra. So, if you are running on High Sierra and have mid- to low-end hardware, my advice is to turn Vertical Sync off.Hope this may be of help.

From my understanding, the disk I/O bug was not a High Sierra-specific problem. My wife plays on a 2011 iMac with Sierra and suffered from the disk I/O bug since the initial 64-bit release. The recent bug fix improved performances on her iMac so much that she could raise the settings and is now playing with most settings to Medium. She's extremely happy now, in fact. She says it looks almost like a new game. Regarding my experience, what I can say for sure is that High Sierra triggered the disk I/O bug for me. I was not experiencing it with Sierra. I don't know the reason, and as a software developer this makes me curious enough to ask for a post-mortem about the bug. Now that the disk I/O has been fixed, my experience with High Sierra is equivalent to what I had with Sierra. If there's a difference it is so minimal I can't say what it affects or of how much.

As a Mac/iOS software developer, I would be interested in reading a post-mortem on this disk I/O bug. It puzzles me how a bug like that could have slipped beyond testing and why it took so long to fix. I would really appreciate a technical report.

Briefly tried the updated Mac client this evening. In 40 minutes of play the disk reads totaled under 2.8 GB, which is fair. Moving from one location to another was almost instantaneous, and performances were much better, at least to the level they were with Sierra. I am hopeful you guys got it right and fixed that damned bug. Can't wait to enjoy smashing some more chacks this evening.Thanks, sincerely!

I recently had to switch to High Sierra, and now the game is really a pain to play: There is a sort of latency between action and reaction, even just rotating the view. You press your A or D button and it starts turning half a second later (ping is 63).FPS down by 30% at least: where I previously had 30 FPS (auto-limited), now I am around 20.The CPU usage is higher than before (around 150%, while previously it was around 100%). In fact the fans spin noisily, while before the Mac was almost silent.Last but not least, the client continuously reads from the disk at a pace of 10-30 MB/s, to the point where in 30 minutes of play it has read more the entire size of the Gw2.dat file. This does not make any sense.Guys, seriously, optimizing the client for High Sierra is a must. You can't rely on people keeping an old OS version with Apple. They force you to upgrade, in a way or in another. Please, please, please... fix this.
