Blue screen when running AI Dev Gallery model with shared memory

[hansmbakker]

I am using AI Dev Gallery and am trying to use the shared memory of my internal video adapter to allow for using larger models on a GPU.

To do this I modified DeviceUtils.cs to return the shared memory when an internal video adapter was found.

However, I'm getting a blue screen when running larger models on this GPU.

Stop code: VIDEO_SCHEDULER_INTERNAL_ERROR.

• Run a model of e.g. 7 GB like Phi 3 Medium DirectML using the shared memory.
