forcing stage3d to use opengl

[Guest]

I am having serious performance issues with certain GPUs using dirextX under windows but the same card under OSX runs perfectly fine openGL, i was hoping there is a way to force stage3d to always use openGL over directX on windows.

Why would you want to do this? Benchmarks like this show, that at the moment stage3D performs in general much better under DirectX than under OpenGL? Anyway...here is a project that claims to use OpenGL even under Windows: https://github.com/adobe/GLS3D

Thanks for that, but unfortunatly that code does not appear do what i need to. I need stage3D to choose to use gl under the hood instead of directX rather than a API which looks like gl but uses stage 3d under the hood in what ever mode it chooses

As to why we would want to do this we have found that on some hardware particulay radeon GPU's when stage3D is running under directX the performance is worse than if it was using software mode while the the same cards on a OSX system running gl runs perfectly fine.
