To be honest, I was hoping Juce 6 would have more useful features or longer support in time. Or Juce 7 a good feature set, like a proper replacement for OpenGL (Vulkan). Anyway, if your Direct2D implementation works without the problems that @reFX mentions here, maybe it could worth the price.
But for just faster text rendering and some OSX improvements (I’m on windows only), it barely justifies paying 800€+VAT again (even with the 30% of discount)
