Community help,configurations and settings

[NedLynch]

I know this is probably a lot to ask for, but would anyone be willing to post what the things in the config file mean and how changing especially the graphics values will affect the game?
I think I do recognise some things in there from IL2 1946 but some things and their values are a complete mistery to me.

And if I change the config file should I also disable steam cloud for the game?

Thanks in advance for any help with this
