please help

i bought IL2 46 a while back from GOG.
and i enjoy it just as much as i did back when it was released all those years ago.

my issue is with the graphics. first of all i use to run this game in perfect back in the day so i know about open gl and settings in the config file.

the thing is that for the life of me i can not set this game on perfect.
if i set it on perfect the game does not run right and the water shows as this solid dark blue texture. im in windows 11. maybe is dirext x issue?
or is it this GOG version? by the way i have upgraded the game to 4.15.1
