Windows on Arm finally has legs
What is the performance of Microsoft's Prism emulator?
Microsoft's Prism emulator promises a 2x performance boost in the next generation of Copilot+ AI PCs and even current-gen options3. It is designed to run x86-64 apps on ARM-powered Windows devices, translating the underlying code of software built for traditional x86-64 binaries used by Intel and AMD chips2. The emulator is claimed to deliver near-native app performance, making it a crucial component for running legacy applications on ARM-based devices.
What challenges do external devices face with Windows on Arm?
External devices can face compatibility issues with Windows on Arm, particularly if they require specific drivers that are not supported on Arm architecture. This can affect accessories like printers, scanners, and VPN adapters. While many common peripherals work with built-in drivers in Windows 11, some may need updates or native Arm support from manufacturers to function optimally.
What is the status of VPN compatibility on Windows on Arm?
VPN compatibility on Windows on Arm has improved, but some apps like Bitdefender, NordVPN, and Private Internet Access still don't work2. VPN developers use TAP and TUN virtual adapters and devices, requiring a signed driver from Microsoft for correct functioning2. However, Android Authority reports that VPN developers are working on ARM64 versions, which is encouraging for future compatibility.
