Question about Windows XP support

Why you so obsessed over DirectX9? :stuck_out_tongue: it’s a rendering libery, something that you wont have any interaction with in UE4 (or else you gonna play around with custom node in materials or go deeply in to engine source code) regardless if you use DirectX9, DirectX11 or OpenGL. And as said above OpenGL is a lot better DirectX 9 on XP
