Hi
Are all the client settings on lowest? I’d also try turning on “Run clients with DX9” in the launcher settings, although it should default to this.
Does changing the resolution / window mode change anything? Is the MacBook plugged into a power outlet? I know that Wine sometimes struggles when any sort of power saving kicks in.
This is going to be really difficult for us to debug. Officially we only support 10.13 and higher, and I don’t think we have any Macs going back to 2011 or machines that have older versions of MacOS on.
What’s the ticket number?
