I run DirectX for the moment and I tried OpenGL. I have OpenGL 2.1 and it's doesn't work very well. I think they have to fixe somethings in 4.13m, because that's what I have even If I change the conf.ini

I don't really understand my strange line in the cloud.
I have an integrated Graphic card and I run the game at 40-50 fps without problem and just want to have 3D water with water=3, but nothing work. I just think that could be easier to put the option in the game instead of conf.ini and don't block the option that you card might not support.

EDIT :
Just for fun I run a benchmark software and lol. I run at 6fps (Unigine Heaven) in directX 9 mode. I run that with Antialiasing x8...
Just to say that IL2 require a lot less graphic power and I have Opengl 2.1 (the test require OpenGL 4.0 to run the test in OpenGL) and Il2 1946 need to have a forced antialiasing like this test. My graphic card can't support natural antialiasing and just work with forced game antialiasing... (I discovered that with this test, because antialiasing look working.
I'm sure that Il2 1946 in OpenGL 2.1 can be run at 40fps on my small graphic card. I know that's not a gaming graphic card, but Il2 1946 work very well.
