The graphics settings on the pro have nothing to do with resolution. One favours graphics - apparently either at or very close to Ultra PC settings, the other favours smooth frame rates. Both are better than standard PS4 settings.
I don't get why they can't publish the Pro patch details. It's basics man. Serious let down

and the no hdr thing is unexplainable. I'm tired of developers not communicating the reasons behind these decisions, or sharing the Pro patch roadmap to manage expectations. Edit: I have ED on PC but PS4 Pro is my platform of choice. This is why I'm adamant about these details. They should have been provided ages ago.
