Anti-aliasing OpenGL Intel HD 4000

Hello everyone,

AntiAlias does not work with OpenGL on one of my computers, it works fine with Direct3D9. It has a HD 4000 Intel graphics and everything is up to date. I can get FSAA x8 to work using OpenGL Extension Viewer but it looks like no matter what I do, Irrlicht's AA won't work. The only time AA doesn't work with OpenGL Extension Viewer is when i pick "FrameBufferObject" as Frame buffer.
Since I could not find any reliable information I thought I'd post here before I start looking at Irrlicht's source code in case you can provide me a simple and clear answer/solution.

Irrlicht version : 1.8.3

I tried with 2, 4, 8 and even 16, none worked. I used the Win32Window example to test it, i only added a line of code to enable AA in the params just before the device is created.

It looks like this guy http://irrlicht.sourceforge.net/forum/v ... =4&t=50910 had a very similar issue.
