这是你的 Windows 版本/配置问题。你正在使用 Windows 7 或 Server 2008,这些版本在没有用户登录(无头)时不支持硬件加速,至少需要有一个用户登录。
在你的“自动模式”下,当没有用户登录时,它会抛出一条警告信息:
2018-02-21T21:05:58 MCEBuddy.AppWrapper.Handbrake → Starting process as a UISession process with Admin privileges. This requires atleast 1 user to be logged into the system (remote desktop or locally)
ERROR> 2018-02-21T21:05:58 → StartAppWithAdminPrivilegesFromNonUISession WTSQueryUserToken failed (No logged on users) with error 1008. An attempt was made to reference a token that does not exist.
WARNING> 2018-02-21T21:05:58 MCEBuddy.AppWrapper.Handbrake → Unable to create UI Session process with Admin Privileges from NonUI Session. Is any user logged on?
因此,它会回退到非用户会话,你的显卡驱动“缓慢”运行,大约只有 50fps
