Look at apex ?

Although there's a setting for helmet look at apex nothing seems to happen even set to 100% ?

 

You need to be in Helmet view for it to do something. That's the second view after cockpit view.

 

Thank you, I'll try that

 

Also don't forget you can turn off the helmet in helmet view, which gives you cockpit view with look to apex etc
Something I find works well for me is to use helmet view with no helmet or depth of field, and very low movement on all the sliders, like 20% on G-force, leaning etc so you can get it to be so subtle that you barely even know it's working, but gives a nice sense of immersion without it being too obvious or disorienting.
