In theory yes, but in practice I've heard of all sorts of problems when ANGLE gets used on XP (from rendering errors to plain random crashes). I *think* upstream doesn't even bother of supporting XP any longer, but maybe someone else knows more...

Re: [Interest] Qt5 with qml 2.x on Windows XP... problems?
Thanks for clarifying that. So it seems unless your embedded XP systems have after market 3D graphics cards, you can't succeed in the move to QtQ2. If you can upgrade those systems (Are the AGP? or PCI? (You can get a video card that will likely work for about $25-$45 USD) ) Thank you (and all the others, who answered). This is exactly, what I expected. Today was my first day on that project. And when they told me they would like to upgrade, but still have XP systems, which has to be supported, immediately some alarms went off in my head. But Windows isn't my preferred system, especially nothing before Windows 7, so I wanted some confirmation. Since I am so 'fresh' in this team, I cannot give more information about the exact hardware and driver situation.

Re: [Interest] Qt5 with qml 2.x on Windows XP... problems?
Another option is to use a software rasterizer (Mesa llvmpipe). It may not perform well, esp. on old machines, but could be an option in some cases. There is also the Qt Quick 2D renderer, which takes GL out of the equation, but that's commercial only.

Re: [Interest] Qt5 with qml 2.x on Windows XP... problems?
Please be aware that performance wise, you may have issues. Vista was the first version to require some 3D capability. XP has GL (opengl32.dll), but only a very simple implementation. Most vendors (NVidia, ATI) supplied their own GL driver. It is my understanding that QtQuick 2 assumes GL. I am not sure what version of GL it requires. I'd be willing to bet that the default driver in XP is insufficient. There may be a raster back end, but I could have sworn that GL was the core reason for the difference between QtQ1 and QtQ2?
