Viewport pixelated, low res

When pressing play on any project the camera view is very pixelated as if the game is running on a lower resolution. The actual viewport in the editor is not affected by it. Happens across all projects, even the sample content ones. And this started last night so my guess is I accidently downgraded the display quality in the editor, but I can not find what setting controls it. Any advice on this issue?

You could try Settings -> Engine scalability settings

Thanks that fixed it.

Thank you for posting this. I have know idea how my settings got changed but that was driving me nuts. This totally fixed my issue.
