Description
There are frequent questions on #performance about poor FPS in E6 with otherwise decent systems; these are frequently addressed by changing the following in forge-client.toml:

alwaysSetupTerrainOffThread=true

I'm not clear that there is a downside to making this the default; if I understand correctly the potential downside is with low core count systems, which for lots of reasons probably won't run E6 particularly well anyway.

There are issues with chunks not rendering or even only partially rendering with this option. Also some general rendering funkyness that can occur. Which is why it is not default.

Interesting. If it's unstable I suppose making it the default doesn't make sense. I suppose we can just keep pointing those with FPS issues at it when they ask ^_^
