affinity

The affinity tag on WindowsForum.com covers discussions about setting processor or interrupt affinity in Windows. A common topic is changing the interrupt affinity policy for drivers like DirectX.sys to reduce interrupts on core 0. Users explore methods such as registry edits and the Windows Driver Kit (WDK) to assign specific affinities to specific cores. These threads focus on low-level system tuning for performance optimization, often involving hardware interrupt handling and driver configuration. The tag is relevant for advanced users seeking to control how Windows distributes processing load across CPU cores.
