No Man's Sky: game slows to a crawl after having been in the background for a few minutes

[lgarron]

• Start No Man's Sky on macOS in full-screen.
• Switch to another app.
• Wait 5 minutes.
• Switch back to No Man's Sky.

Observed: the game runs at less than 1fps.

Expected: the game resumes playing.

I have only found one workaround, which is to quit the game (hope it autosaved recently!) and restart.

My guess is that some sort of background throttling is put in place when you move the game to the background, and that throttling is not properly removed if you are away "too long". (Perhaps if a certain event happens in the meantime, like an autosave.)

It doesn't seem to matter:

• If you "pause" the game in a UI screen (using e.g. Esc) or stay AFK "in-world".
• Whether you're using a built-in MacBook Pro screen or an external monitor.

This hasn't been an issue recently, although I'm still super careful not to leave it in the background too often (or for too long).
