Microsoft just improved dGPU performance on Windows 11 laptops (CASO) (devblogs.microsoft.com)

"In our tests, on a select set of popular PC games, we observed an average of ~16% FPS increase1 and ~27% display latency reduction1. In addition, CASO contributed to a 45% decrease in timeout detection and recovery events (TDRs)"

Cross Adapter Scan-Out (CASO) can improve the performance of hybrid laptops that have both an integrated GPU (iGPU) and a discrete GPU (dGPU) or external GPU (eGPU). CASO is a feature of DirectX that allows the dGPU/eGPU to directly display the rendered frames on the screen, bypassing the iGPU. This reduces the display latency and increases the FPS for gaming scenarios. CASO does not require any specialized hardware solutions like NVIDIA’s Advanced Optimus or AMD’s Smart Access Graphics (no mux switch needed), but it does require Windows 11 and compatible hardware (AMD 6000, Intel Iris, any nvidia dGPU).

It sounds more like they finally unfucked their own display subsystem.

Possibly. It also suggest you'd get all these benefits by just disabling one of the GPUs, because unless battery life is a concern for your gaming laptop the difference in power draw on the desktop will be fairly minor.
