一般情况下会与VGA(甚至是屏幕)滞后有关,比如当你的显卡集成了显卡并共享了处理器功能时,在高处理器负载时的低帧率等。如果不是这样,Windows有一些配置会影响到这种性能问题。这个链接](https://support.steampowered.com/kb_article.php?ref=5365-RXBN-5508)提供了很多排除输入滞后的提示,mst只针对游戏,但另一个是一般的输入滞后,可能会对你有帮助。检查一下,如果你没有错误地启用了这些配置:
Windows Vista/7 Mouse Options
Go to the Start > Control Panel > Mouse
Click on the Pointer Options tab
Ensure that Display Pointer Trails, Smart Move, and Acceleration in Games options are disabled (some of these options may not be displayed, depending upon which version of Windows you are using)
Exit the Mouse Properties window by clicking OK to save your changes
Windows Vista/7 Accessibility Options
Go to the Start > Control Panel > Ease of Access Center
Click on Make the keyboard easier to use
Ensure that Turn on StickyKeys, Turn on FilterKeys, and Turn on ToggleKeys options are disabled
Click on Set up Stickey Keys and Set up Filter Keys and uncheck the Turn on Sticky Keys when SHIFT is pressed five times and Turn on Filter Keys when SHIFT is pressed for 8 seconds options and click Apply
Exit the Ease of Access Center window by clicking OK to save your changes

另外,可能与键盘芯片(嵌入式)、键盘线甚至USB/PS2接口有关。如果还是出现同样的情况,我会用另一个键盘检查一下,如果还是这样的话。
