Phenomena
After installing WINDOWS10 on Macbook, install the graphics card driver
Running some games may prompt DirectX not finding, error, or D3DERR_ NOTAVAILABLE
After uninstalling the graphics card driver, the game is normal
But I really want to install the graphics card driver.
Solution
Reinstall BootCamp: https://www.iplaysoft.com/bootcamp.html.
Possible reasons
Guess that the graphics card driver needs to use Apple customized Intel drivers instead of Intel universal drivers.
