Difference between OpenGL & DirectX?

[Erzeal]

Like most have said. Both have their Pro's and Cons...
I prefer to use Opengl when i can...but unfortunately it seems i have to use Directx for IL-2 1946 cause i get severe slow downs in Opengl mode, i'm not sure why. The directx mode runs smooth except for occasional hiccups with large explosions. Probably just some quirk with my GPU.

il2 looks better in OGL

And it seems to run better too...fixed the severe slow down i was having...just had settings turned on that were too high. Runs fantastic now.

i just get a black background with opengl in perfect mode ..shame

In OpenGL mode it's now impossible for me to use the mouse on the game GUI because the fps is so low - and this is before I've even rendered anything! Once the game starts, things become a literal slide-show. I also cannot run "perfect mode" at all (grey-out option). Lastly, there are numerous artifacts in clouds that would be a big immersion killer.

DX runs smoothly, and quickly on excellent settings...Maybe it's because I have a horrible Intel GPU which is probably designed to handle other drivers poorly and have DX perform the best on any given function.

For il2 Open GL looks better, and run fast, you can archive Perfect mode.

With DirectX you can´t go to perfect mode for IL2.

Nvidia graphics card run very good OpenGL.


ATI graphics card run very bad OpenGL, for IL2... maybe a eternal drivers problem.

When an explosion or smoke is showed ...
The FPS going bad in DirectX , OpenGl runs better in those situations and get up the minimun FPS vs DirectX

This is only for IL2

OpenGL was my choice for 1946 and mods. I really liked the perfect mode. Currently I can't run the 1946 in OpenGl anymore. The graphics are garbled as the cards would be damaged. Directx is the only mode the game picks up with no problem. Could be an issue with the CAT 11.5.

Altough i've got CloD, 1946 with the mods will remain major for me to fly. Let them sort out CloD first.

(Ridiculous that you can't fly it with quadcore and crossfire cards....)
