Latest OpenGL Supported by Irrlicht [Solved]

Just a quick question.
Which is the latest OpenGL version supported by Irrlicht?
3.3 or Maybe even 4.0?

I have OpenGL 4 card but even if I recompile Irrlicht, I only get 3.3.

When you run Irrlicht, it will say whatever the highest version of OpenGL is currently supported by your video card and drivers. For instance, I have a Radeon 5850 so it says I am using OpenGL 4.0.someothernumbers but that doesn't mean it is using any 4.0 features. Irrlicht only uses OpenGL features up to, I think, 3.2.

As for what version it is reporting, if you are currently supporting OpenGL 4, it should show that. Either you don't have all of the drivers up to date (The prepackaged NVidia drivers only do, I believe, 3.3 and only 3.2 for ATI so you have to get the latest from their websites.) or your card doesn't support OpenGL 4 (Only ATI Radeon HD 5xxx cards and NVidia I think just the GeForce 4xx cards)

It's a HD5970, with latest drivers! How can it not use GL 4?
Well I'm gonna look into this problem a little more, keep the suggestions coming.

That is quite strange. Like I said, irrlicht reports OpenGL 4 for me. You have the 10.6 catalyst drivers?

Yes, The 64bit version. But I think the problem lies with the opengl sdk, here. So I'm downloading the latest windows sdk now, since that includes the opengl lib and headers.

The Windows OpenGL SDK only has OpenGL 1.1 functionality. You can find gl3.h on OpenGL's website. I believe they also have an appropriate glext.h I don't think that's the problem, though, because if it was, you wouldn't be seeing OpenGL 3.3

Irrlicht support OpenGL 2.0 features in the core (it support also 3.0, but in not efficient way). What You're seeing at the Irrlicht start up is only info about OpenGL version in Your gfx drivers.

Ooops, Sorry guys.

Problem solved, I accidently capped my driver at OpenGl 3.3, in order to run a game which threw issues when using OpenGl 4.

But thanks for the extra info aswell.

Haha, that's awesome.

By the way, what tool did you use to cap your OpenGL version? I wasn't able to find one for ATI cards, I know for NVidia you can use Riva Tuner. I'm gonna need to test out some OpenGL stuff later, so if you can show me where to get a tool to limit OpenGL versions that would be cool.
