The game uses OpenGL on macOS which is the single biggest performance killer here. It is no secret that for some time OpenGL is in a bad state on macOS and unfortunately ANet opted to use that over the more advanced Metal API. Aside from this, the game is also better optimized on Windows. Currently your alternatives are 2: Setup Bootcamp with Win10 just for the game or install a modern Linux distro (the latter might be a bit tricky). I really tried everything... and for me* the native macOS 64-bit client is still the best solution (as hard as it sounds...) Bootcamp using Windows 10: Doesn't really support eGPU, there are hack-arounds on the web, but I didn't get it working at all. And anyway all those hack-arounds seem pretty fragile (concerning OS updates, etc.).Parallels Desktop 15 using Windows 10: Despite advertising to be optimised for gaming, the performance is still worse compared to the native macOS clientWine: No macOS Catalina (64-bit) support yetCodeWeavers (commercial wine version?): Performance also worse compared to the native clientWhat else could we try? :-)Buying a Windows PC? ;-)*MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports), i5 (2.3GHz), 16 GB RAM, Radeon Vega 64 8GB (inside Razor Core X eGPU housing) For comparison: Playing Heroes of the Storm in 4K at pretty maxed out settings runs at around 100fps.Guild Wars 2 doesn't really care much about the settings, it always sucks in performance. At least using 1080p, and turning down shadows and/or reflections were really the only settings that very very slightly improved the performance. The FPS really are going up and down, but there is definitely visible stutter at around 5-15fps in cities or so, and I think I never really get more than 30-40fps (very very best case). Especially when entering a new zone (e.g. teleport) in the beginning it's so sluggish, and almost unplayable. -.-
