> i'm playing a bit fast and loose with what lives on the GPU and what lives on the CPU here. On many systems, they share a memory pool anyway. But on systems with discrete GPUs, most of this is gonna be video memory

Yeah this is irrelevant here, windows doesn't share both in 99 of the case.

What do you mean by "windows doesn't share both"? Windows doesn't get a say, Intel iGPU systems literally don't have video memory

DWM quite literally does that all the time. For the general case it allocates GPU memory, but also swaps to system RAM or uses it as a synchronization mechanic when you have one screen on an igpu and the other on a dgpu.
