What is DX12?

[Lanksta902]

Myst was working fine yesterday, today it tells me DX12 is not supported on my system and brings up some -dx12 thing?

DX12 is "DirectX 12".
DirectX is a graphics display framework supported by almost all PCs.
If it was working fine before, and not today that either means something went wrong in your PC - drivers, hardware, etc, or that you started it in a different way this time.
One of the first things to try would be to restart your computer and see if the problem fixes itself.
Some games can be started in DX10 or DX11 compatibility modes as necessary.
Not exactly sure about the message, but -dx10 or -dx11 would be a command line argument. You'd enter this under the startup parameters\options somewhere which tells the game to run in that mode specifically.

To see what version of DirectX your computer supports:
Right-click your Start Menu and select Run. Enter "dxdiag" and click OK. The first page of the DirectX Diagnostic Tool will list your DirectX version.

The same has just happened to me. Yesterday it worked fine, today however, the mouse doesn't work on any buttons in the menu, and the graphics are distorted. I've made several attempts to fix/workaround this to no avail. It's likely I'll refund now.

DXdiag says no problems detected

Sounds like it could be a recent display driver update, maybe?

Strange... we haven't pushed a Myst update to Steam in a long while, up until today. This does smell like a potential driver problem. Has the issue been resolved with a graphics driver update?

Make sure all your drivers--especially your graphics card drivers--are up to date.
