Sort of. I think it's encrypted and gets decrypted when launched.
Just changing between windowed mode and full-screen and then changing the resolution seems to have restored the 4-way AFR.
Also, in my screencaps, it doesn't look like I was using max details. There is a "high" shader detail option that I thought was max but "highest" was the max setting.
Edit: Strangely enough, it seems to run better now that settings are maxed. I didn't drop below 60fps in the area I was in the 40'ish range when using "high".
Here are a couple now that I have it set to highest. I guess I'd have to compare from the same spot to notice the difference. At first glance, I don't see anything obvious.
