I'm using Irrlicht in my project and I have a problem with rendering scene on different graphic cards.
EDT_DIRECT3D9 mode works fine anywhere.
EDT_OPENGL mode works fine, but on the integrated graphic cards and some notebooks picture looks bad.
What I need to do for correct work in OpenGL mode?
Here is two screenshots from the same computer with integrated graphic card
Direct3D looks fine
