I have the update and it definitely fixed the Netflix and fixed Amazon Prime video playing issue. Before the update I had to use Intel iGPU to watch Netflix.
Unfortunately the service still not accessible in my region (outside USA). I tried registering and paying for the subscription but it asked for a US zip code :(. I could ented a fake code but i'm not sure if i can bypass their geoblock.
Your fellow here from Oman....I use Tunnelbear (Thanks to Linus). I use the free 500MB (per month) version. I may upgrade in the future to 1 year plan, because It's getting rediclos down here.
Did you install Windows? If no than install it. If yes than start installing drivers for GPU , network adopter...etc. DirectX comes within Windows you don't need to install anything it's just part of the OS.
