How does the driver interface work?

IsoKey utilizes a custom-signed kernel-mode driver that hooks directly into the Windows Human Interface Device (HID) stack. By intercepting raw input packets at the lowest level, we bypass the standard message queue, allowing for absolute isolation of secondary hardware from your primary system input.

Is there any input latency?

Because the interception occurs at the driver level rather than the user-mode hook level, latency is effectively sub-millisecond. In benchmarking, IsoKey overhead is statistically insignificant compared to native Windows input processing.

Is IsoKey safe for Anti-Cheat?

While IsoKey uses kernel drivers, it does not use "cheat" techniques like code injection. It is a legitimate productivity tool. However, some highly aggressive anti-cheats may flag the driver signature. We provide a native uninstaller to completely remove all hooks when not in use.
