Hmm, so you have a notebook with a powerful notebook gpu. Can you check if it works with lower settings? Especially with a lower internal resolution? It could be that something is messed up on systems with 2 gpus.
Yes, it works in D3D. mimimi, surprisingly it does work at lower IRs. Anything below 3x works, it seems, and anything 3x or above (including 3x) doesn't work; I didn't notice this because I always play at 3x.
What GPU do you have? (or GPUs if you have an optimus setup)
I do indeed have an optimus setup. My integrated GPU is an Intel HD 4600, and my dedicated GPU is an Nvidia GeForce GTX 980M (driver version 365.19).
As usual, optimus is a neverending source of graphics issues.
Nvidia driver 368.22 still has this issue
And D3D12 also works.
Working on a fix for this.
