Pc usable without graphics driver?

Moin I wonder what happens when I e.g. I don't install graphics drivers on a gaming pc, I know that the resolution does not look nice but the point is you can play games like Fortnite Apex Cod and so on without a graphics driver or does anything happen?

Win10 ALWAYS installs graphics drivers otherwise your screen would remain black

Basic drivers are always involved, explicit ones should be left out

But is nonsense, because otherwise you can't use the performance that the graphics card can develop

It happens that many features of the graphics card are unusable and that there can be nothing else

Thank you

Thank you
