![]() To solve this, by default, MBPs with dGPUs boot into Bootcamp with the iGPU disabled-something that, as you've discovered, can be problematic.įor reasons, this is a particularly sticky issue with eGPUs. However, although Windows does have graphics switching, it isn't as well integrated with Macs. ![]() ![]() ![]() Under macOS (and Linux), this is handled by the OS and drivers sending the appropriate commands to the hardware and switching when needed. The long and short of it though is that the unique hardware architecture of the MacBook Pro means that it can't just operate like most other laptops. If you want to read about this more, I recommend you read up on the Linux kernel's documentation or Arch page on hybrid graphics. By contrast, most other laptops simply share a framebuffer which both GPUs push to and the display can read from via some methodology. Unlike most other laptops, MacBook Pros with dGPUs use a graphics muxer to physically switch which GPU is pushing pixels to the display.
