Project Build Quality Changes?

Hi all, hopefully this is the correct space for this - I need help. I have a project that visually looks great in the view port, frame rate is high (between 50-80fps) and also when I run in a window in UE4. But when I build\cook the project for windows and run the app, the graphics automatically change to a lower quality automatically. How do I force it to be at the best quality?
Check out the attachments. Quality is set to cinematic and lighting build I have tested at preview and also production and I still get the same results. The better quality is within UE4 and the lower quality is from the build. Any words of wisdom? Help would be very much appreciated!
