Sorry, I should have been clearer: I mean there's an issue in High Sierra (that wasn't in Sierra) that degrades performance with all OpenGL apps and lags the entire OS while OpenGL is being used after it's been asleep at least once. Restarting restores performance back to what it should be, until it goes to sleep again, after which it'll cause the problem again. It may not be impacting all hardware configurations so you may not be experiencing it, but I've now seen other people mention it with other games as well.

Unfortunately their system doesn't allow the tickets to be viewed by the public - only the original submitter and Apple can see the content of it. But if you're planning on submitting your own report and want to reference mine, the radar number of mine is 34677832. I'll be interested to see if my radar gets marked as a duplicate of an existing report as well. For these types of bugs, submitting a report involves running a couple of utilities while the issue is happening to provide diagnostic system information ("sysdiagnose") and the files that generates can be a few hundred MB, so it can take some time to upload it.

Another update on my High Sierra performance problems: same thing happened again, terrible performance after leaving MacBook Pro closed for a while and coming back to it. A restart fixes it. Must be a bug in High Sierra. Groan! Edit: I've created a radar bug report with Apple about this issue. Will see if I get a response.

UPDATE! A restart fixed it. Looks like there's a bug in High Sierra that sometimes causes OpenGL performance to be destroyed after the computer has been asleep once.

EDIT: As per my post below, restarting fixed whatever was going on. It looks like there's a bug in High Sierra that sometimes causes OpenGL performance issues. The original symptoms were (on 15" 2016 MacBook Pro (16 GB RAM) with Radeon Pro 460 (4GB RAM) and settings on low at Full Screen 1680 x 1050) that after installing High Sierra GW2 frame rate was half what it was before and the entire OS was lagging badly while GW2 was running. I'll keep an eye out and see if I can replicate the circumstances that cause it to start happening, but it looks like a High Sierra bug and not a GW2 issue, and restarting fixes it. Hopefully it's not something that's going to happen regularly, but I guess time will tell.

As Jon said, "For anyone having issues that has yet to post their system specs, please do so."

For those wondering why they can't distribute the 32-bit wrapper client any more, it could be because of legal/licence reasons. The company (TransGaming) that created the wrapper system (Cider) sold their tech assets to other companies like Nvidia and became a real estate finance company instead (Findev). I'd imagine that companies like Arenanet had a licence to use Cider that they can't renew because it's no longer offered as a product. Even if that's not the reason (but it seems to be something along those lines because it's been said several times that it's not currently a technical issue), now that Cider is no longer available it's only a matter of time before an update to macOS or something else breaks it in a way that can't be fixed, so the only path forward is developing a native client, even if that's painful in the meantime.

Along with a bunch of other fixes that were noted in the release notes, it also looks like ambient occlusion setting is now properly saved. Thanks!

Ambient Occlusion setting isn't being saved. I have it turned off because it's causing a weird halo around all objects (another bug), but every time I close and restart GW2, Ambient Occlusion gets turned back on and I have to go into the settings and turn it off again.
