[4.6 Preview] Why half res when playing ?

Why does the game seem to render in half res (all blurry and jagged edges) when playing in the editor on in a new window? Its looks fine in the editor without playing.

Thanks

Check your Scalability Settings found in the Settings button on the toolbar and make sure you have it set to Epic (or high). If that doesn’t work, try fix by DJ-INSERT here:

If it doesn’t help could you post a screenshot for us? thanks.
