No...no one is saying it is the fault of the OS....
But you did when you told another person having this problem was because of Windows 7, and even suggested to "upgrade" the operating system (

It is almost ALWAYS the fault of the Display Adapter and Drivers which for some OS' is lacking and no longer supported for modern standards or came with a video card that really isn't up to snuff to play a modern 3D rendered game that uses much of DX11 and 12 to render it's graphics.
Yes and no. I've shown that some older cards are able to handle this game in an earlier post several pages ago. Most of the problems with the drivers is because of an upgrade or because one is allowing the OS to update drivers via Windows Updates. In my past experience, having the OS update the device causes more problems than it solves, and in most cases actually makes things worse. So it's not always going to be the video card. In most cases it's due to the drivers themselves.
A directX12 card comes with drivers and libraries to support DX12 regardless of what is in the OS itself...
A DX10 card that hasn't had a driver update for that OS you are running since it came out will have problems.
DirectX isn't a device you can go to the store or online to purchase. So there is no such thing as a "DX card".

Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms.
WIn10 Drivers are ALL compatible with DX11 and 12 but not all Win7 drivers are...
And therein lies the problem some people are having. You are at the mercy of the GPU Manfacturer's support and for folks with nVidia and Radeon cards that isn't a real problem....
Those who have Intel or some other company's GPU may or may not have the drivers to play. And those with onboard display adapters are usually the ones who don't get driver updates since the Mobo Manf has moved on and would rather you buy another motherboard than spend money on making up to date drivers for you.
Again, if you had read my previous post (

My conclusion is that if those who are experiencing this problem uninstalled the drivers for their video card and reinstalled using the software that came with the PC, motherboard (if you're using integrated video) or from the card's manufacturer (if you're using an expansion card - ex: PCI or PCIe), disabled the driver update through Windows Updates and not allowing the driver software to install any new updates, that will most likely correct the problem.
However... I am still waiting on my VM to finish Windows Updates before I can continue with any further testing.
