[Interest] Qt5 with qml 2.x on Windows XP... problems?

[Michael R Nelson]

"Since you're on XP you can't use ANGLE as a Direct3D fallback"...

I believe DirectX is available for installation on XP. Can ANGLE be used if Direct3D/DirectX is installed on XP? 

Thanks, 
Mike

For the record, Qt Quick 2 on desktop requires OpenGL 3 (or 2.x + the FBO extension). As Microsoft only provides OpenGL 1.1 in the system opengl32.dll, you need the one supplied by your GPU vendor with the drivers. NVIDIA's drivers are just fine, for ATI's ones YMMV, Intel's ones just don't work on XP -- period.

Note also that since you're on XP you can't use ANGLE as a Direct3D fallback.

Hope this helps,
