I have the same problem since i updated windows 10 pro x64 to preview build 15025 :(

//edit2: this does not work.
I think it has something to do with opengl and the mobile nvidia card.
Now Avorion shows a white window, i can hear the music but cant see anything.
Same with No man's Sky.
Any idea how i can fix this?
