Do you have DirectX 9 End User Runtime installed? If not, -video d3d will not work. It supports DirectX 9 only. 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.

Actually, it's possible this is perfectly normal. 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.
