Outlines around people pixilated. How to fix?

Have the outlines always looked like this? If not how do I fix it? Is there a simple setting I can change?

I didn't notice this type of low res outlines before tonight.

Here is an example: http://i.imgur.com/eskC1ka.png

I posted it on the subreddit and others are having the same issue.

This is a problem with the darkness effect. Just try to get through Act 2.

As OnmyojiOmn mentioned this was caused by the darkness effect in Act II.

Here is a show after getting done with Act II: http://i.imgur.com/q699OqE.png

Maybe GGG has some more optimization to do to solve this. At least know I know what caused it and not that I was crazy and forgetting what the outlines looked like.
