Difference between OpenGL & DirectX?

I know nothing about either of them but I do get entirely the opposite effect here; when I use OpenGL my game looks smoother and more real?

I get better fps with DX so I use that when online and I use OpenGL for flying offline and taking screenshots etc. since as far as I know you can only use "perfect" settings under OpenGL.

The textures get filtered with DX so you can see the IL2s 8bit-textures with just 256 colors looking much smoother. DX also eliminates microstutters experienced during online-play largely.

That has little to do with FPS, though. You get better FPS because you can only run the game in perfect mode under OpenGL, as you posted correctly, which directly effects rendering-distance for the landscape, for example.

So while the whole game looks better under OpenGL at perfect mode, the TEXTURES look smoother and more realistic under DX.
