OK so the text is being mipmaped as everyone else has said, but there’s a texture for that. Click the text actor, open the material for it, find the texture for the alpha, open that, and change the mipmap settings there. that will fix the text issue.
For the motion blur, Epic have made a pretty **** move imho (I mean, i get it, defered rendering kinda makes it mandatory, but still). there’s a default post-process setting within the camera that over-rides a lot of these settings. if you set your post-process setting to anything higher than ‘0’ priority] that should fix that issue.
