Summary	07024: Hardware acceleration not working
Description	MAME d3d is failing to do hardware acceleration, graphic shows that every time it try, the render keep falling back to software. Second screen shot added to show the GPU usage when hardware acceleration is working. The software used is from AMD, it comes with the driver to monitor the graphics card usage. Red line is software activity.
Steps To Reproduce	Any working machine, use -video d3d

Later versions of DriectX are not backwards compatible, but you can still install the DirectX 9 runtime on Windows 7, 8 or 10. If you want to use DirectX 11 or 12, you can use `-video bgfx`. MAME does not support DirectX 10.

Most of what MAME does with the GPU is just uploading a textured quad for each rendered frame and letting the GPU scale it to fill the screen window. That's virtually no work for any modern GPU. I'm closing this bug since you haven't actually shown any errant behaviour. Please think before opening bugs and wasting everyone's time. You will be demoted to viewer status if you continue to open pointless bugs.
