OpenGL doesn't work on Intel HD Graphic???

[IceFire]

I *think* IL-2 was programmed in OpenGL 2.1 but I wouldn't get too hung up on the OpenGL version as IL-2 is very old.

The bigger issue is that your graphics system is designed mostly for low powered performance. 3D acceleration on the Intel GMA cards (including the "HD" versions) is oriented around acceptable throughput for running HD video streams and having a smooth experience in Windows Vista/7.

Even bigger an issue is that Intel may say that they support OpenGL 2.1 but it's not likely to be an optimized implementation. They did it to check off the boxes for simple OpenGL applications but flight simulators may be right off their charts. If you can get it running in Excellent mode I'd say you're doing very well. If it works at all in Perfect I'd be surprised.

The guys on the thread say you have an older driver version. I'd say try and do a driver update to at least help things along but you may not be satisfied.
