Why LiberNT.
Windows 11 as the reference
Kernel and application behavior follows Windows 11 and is checked against it test by test.
A new NT memory manager
NVS, a clean-room memory and cache manager written for LiberNT, replaces the one inherited from ReactOS and runs faster in our measurements.
64-bit platforms
Native amd64 and arm64, with riscv64 in progress and 32-bit x86 still supported, all built from one source tree.
Windows apps on ARM64
WoW64, ARM64EC and the FEX emulator run x86 Windows applications on ARM64 machines.
Modern graphics
WDDM display drivers with hardware-accelerated OpenGL and a composited desktop, starting with the Raspberry Pi 5 and 3.
Modern storage and USB
A modern StorPort with an NVMe driver, a new NTFS driver, USB 3.0 through xHCI, SD cards, and USB RNDIS networking and game controllers.
