DirectX 12 book start almost finished!

I thought I would start book on DirectX 12

With a sequence of articles, programs, on DirectX 11on12.
Over the last couple of weeks, maybe a month, you get old and ...

I was converting Microsoft's Marble Maze example, originally VS15, legacy c/c++ to VS17, c/c++ 17.

When, yesterday I got it by accident. It is the most innocuous, unsuspecting accident or recognition of wrong logic that makes a program work. Like the time I took GitHub.com/matt_filer 's DirectX 12 toolkit (GitHub.com/walbourn) example of Super Mario Kart and realized that the whole thing could be upgraded simply to c/c++ 20 after mScene was changed from a pointer to an address - &mScene vs *mScene.

My is Marble Maze fast and responsive!

The interesting thing is all code is nearly the same for a DirectX 11 upgrade to DirectX 11on12 solely by modification of the DeviceResources header and source file of a template created DirectX App Solution.

True, projectMain header and source files need a smidge of modifications.

The nice thing about it all is it is easy to see with a test of the graphics card as to whether a program can be be run in DirectX 11 or 12.

And oh are the graphics sharp!
