Hi, eddyp. I had this problem a lot of time ago, but can't remember what I did to solve it.
Try to install Carmasters mod and set "Water=4" in [Render_OpenGL] section in "conf.ini" file.
Also I recommend to set "DynamicalLights=0" and "Effects=0" there too.
Look at this:

I have this mod installed only on "HSFX 7" and "VP modpack".
This is the version of Carmasters MOD I'm using (CarsmasterWater-512 v.0 02(3.17)).
For VPmodpack or stock game:
https://drive.google.com/file/d/1BWg3mna_UFK1p4ORDo8dJnAsnNFSPSvr/view?usp=sharingExtract folder: "Maps" from "CarsmasterWater-512 v.0 02(3.17).rar\CarsmasterWater-512 v.0 02(3.17)" to the "#SAS" in the root of game folder.
For HSFX use this:
https://drive.google.com/file/d/1UBjd7tyoTX07HmrcW4xm_bKTXzCQJwTp/view?usp=sharingFrom archive "CarsmasterWater-512 v.0 02(3.17)_HSFX_JSGME.7z" extract folder "CarsmasterWater-512 v.0 02(3.17)" to the "jsgmemods" folder in the root of game folder.
Probably you do not know about cirrus clouds feature in GE mod. So additionally you can donwload next archive:
https://drive.google.com/file/d/107ksCcprvNQhBT3Qwb7gIwe_6mpTreI6/view?usp=sharingJust extract content of "il2ge_random_cirrus_textures.zip" to the game root folder.
This will work in next way: "IL2GE will now look if the folder "il2ge_random_cirrus_textures" in your IL-2 folder exist and randomly pick one of the textures inside it.
A new random texture is picked each time a map is loaded."
Also this is content of my il2ge.ini file. You should play with options in this file:
# enable graphics extender
EnableGE=on
# disabling this gives higher fps but looks bad
EnableObjectShaders=on
# enable terrain bumpmapping
EnableBumpH=on
# cirrus clouds - experimental
EnableCirrusClouds=on
# enable shader for transparent objects - experimental
EnableTransparentShader=on
# experimental
RealisticShadowColor=on
# atmospheric light scattering shader
#
# choices:
#
# Default:
# the original shader
#
# Precomputed:
# (experimental)
# precomputed light scattering
#
Atmosphere=Precomputed
[Atmosphere.Precomputed]
# more accurate colors
AccurateLuminance=on
# possible values are between 0.0 and 1.0
Haziness=1.0
# no description
SingleMieScatteringHorizonHack=off
All this is not "official" guide. This is only the steps I did to got GE working for me.
