Improve Screenshot Quality

Is there any way to clean up the screenshot quality? I want to render out a 4k screenshot at 16bit with all the buffer data, but the base image just comes out grainy.

Any pointers appreciated!

Thanks

Hmm, you can be sure to set your scalability settings to max, you can do this at runtime with the console commands seen here:

Then using the HighResShot command you can render at twice the preferred resolution then downscale it to maybe help with the graininess.
