Try as I might - and believe me, I've tried - I can't get il2ge to work on my install. It's probably so simple that I'll kick myself when I get to the bottom of it. In the meantime, I'll give the latest reshade a good going over.
I found that Il2ge must be installed directly into the il2 main directory. I usually install mods into a new folder and then manually copy and paste into the main directory. I do this just to see which files are affected. I tried this with Il2ge and it did not work. I've read that other 'effects mods' can also cause issues.
If you can't install Il2ge then reshade4 is a must. It just has so many more interesting shaders than sweetfx for tinkering by a dedicated screenshootist.
You have to install it from the site into the sim main directory so that it installs the correct dll name(opengl32.dll)
You can copy and paste the files for use in other games taking care to rename the dll to d3d9 or whatever the other sim/game uses.
That second lightning pic looks great.
