I found the best setting is to use the helmet cam, 100 on world and gforce movements, no helmet shown, no helmet depth of field, look to apex 50, helmet leaning 75 and camera leaning 50. I raced in R07 with look to apex which followed your wheel and this feel about the same. LTA on 100 here is overkill.
Yeah, its ridiculous for the fact that you have the DOF kind of built into your eyes, so when racing, you are focused on the road and the motec is not in your focus anyway but you divert the focus from the road to the motec to see it. Why would you want to force the "drivers eyes" to lock onto the road is beyond me. But hey, atleast there is an option to turn it off so thats +1 point for them.
