请自行测试优先级选项
Interrupt affinity 驱动中断相关性

Interrupt-Affinity Policy Tool: https://www.techpowerup.com/download/microsoft-interrupt-affinity-tool/


选择设备 (GPU、USB控制器、音频控制器、USB设备)
Set Mask - 选择CPU 0外单个偶数核心(HT/SMT开启)


自动设置进程CPU相关性、优先级(HT/SMT/小核开)
Process Lasso https://bitsum.com/get-lasso-pro/
基本设置




基本使用
后台程序、服务:
右键点击项目 > CPU Affinity > Always > Select…

选择奇数核心/小核Ecore
酌情降低优先级
游戏、(启动器、平台):
选择除CPU 0外的偶数核心或全部核心(CPU 2,4,6,8…)/(CPU 2,3,4,5…)
推荐选后几个核心,blame microsoft
CPU优先级:高
(某些游戏继承启动器或平台的CPU相关性优先级设置)
系统项system, registry, smss.exe, csrss.exe, wininit.exe, services.exe谨慎设置(基本不管用)
