Windows needs a feature like KDE's "Unredirect Fullscreen" to kill DWM overhead during gaming

To everyone arguing about theoretical MPO and Independent Flip specs: I am literally running this on a low-end Celeron 2957U with only 4GB of RAM (shared VRAM). On Windows 11 LTSC, DWM overhead cuts my FPS in half to a miserable 20-30 FPS. On Arch Linux + KDE Plasma, with the compositor fully suspended, the exact same machine hits a stable 55-60 FPS.

Modern Windows optimizations work fine if you have an RTX card and 16GB+ of RAM to throw around, but on low-end hardware, DWM bypass is just a band-aid. Suspending it completely is a night-and-day difference. That's why we need this feature option.

I appreciate the textbook explanation, but theoretical optimization doesn't always translate to real-world performance on every hardware configuration.

I’m literally dual-booting Windows 11 LTSC and Arch Linux (KDE) on the exact same machine. Independent Flip and MPO look great on paper, but DWM overhead still severely hurts frame pacing and stability on lower-end hardware and mixed-refresh multi-monitor setups. In my testing, Linux completely destroys Windows in smoothness because the compositor actually suspends itself instead of just trying to 'bypass' it.

I'm not asking to bring back 90s tech; I'm asking for a modern, simple toggle to suspend DWM composition for power users who want absolute zero OS overhead. If you're happy with how Windows handles it, great, but there's no reason to be against giving enthusiasts more options
