GPD WIN, xpPhone and Portable Computers

As you want, I am new here, as I saw on the forum that there were more or less interested people I preferred to inform about this problem very inconvenient ...
Where did you buy it from? (GeekBuying, DragonBox Shop, or you were a backer?) Because this problem has been discussed to the death on Dingoonity forums. Kendy also shared some driver files a few days ago, so I'll leave the link here just in case :
I'm a backers, and i can assure you that i did everything that kendy proposed ... and after these tips, i did all that was found on dingoonity, on reddit, and elsewhere (https: // for example) ..... nothing works, 3D games still do not work
