So I just noticed origin pop up and ask to download something, and I was pleasantly surprised to learn that it was downloading another C3 update. Fingers crossed, I logged in, turned my settings back up, and VIOLA! Framerate is back to where it was before the patch throttled it.
Seriously though, that is some good response time. Like, less than 72 hours after the problem, the devs have it fixed. Props to the dev team.
