Elite dangerous graphics setups

Hi guys,
I tried playing ED, on my pimax 8k+ i just got, but in general there are few things that are complete mistery to me.
i just cant wrap my head around tripple settings. What i mean by that, is that i have pitool, i have steamVR and i have in game settings… So how that all affects graphics resolution in VR and settings?
NO matter what i set in steamVR(resolution per eye) , and what render quality in Pitool i set, text in game is not readable. Really low res. and no matter how i change them, does not make any difference.
Can someone with more experience try to explain me how to approach with this?
Does Pitool overrides steamVR settings? of vice versa? or they are add / multiply?

What i noticed, is when i disable PP, and close one eye, than graphics are much better, all text clear, but i have double picture. When i turn on PP, game again looks bad, i can se pixelization and i need to struggle to read text in my ship. But text in menu is better i think.

Also, with all this. where do i start game? i can lounch it from steamVR, from pitool, from desktop or that does not make any difference?

You must edit the SteamVR Settings, maxrecomendeResolution.

Here is a little manual
