Intel(R) HD Graphics

why is diablo 3 running on my laptop. in diablo 2 it asks to update the video card? do something about it

While Diablo III is supported on iGPUs like the Intel HD Graphics, Diablo II: Resurrected is not supported on iGPUs, and only on dedicated GPUs.

You can check Intel’s website if a newer driver is avaialble and if that allows you to play, but if not, there’s nothing we can do.
