    调整你的》偏好设置》解码器设置，然后将vp9以下的（不包含vp9）解码方案选择为HW(AUTO)并勾选使用导致瓶颈的过滤器时，之后选择过滤器设置，尽可能将里面的所有过滤器移除，比如锐化滤镜，去块滤镜，降噪滤镜等针对画面处理的滤镜，因为这些是需要CPU处理的。做完这一切后的速度就是你显卡满速运行的速度，但是显卡本身的编码器或解码器模块不大可能就是100%，比如我的最高只有45%，这是因为显卡统计数据的方式不同，而且显卡的编码器只是其中的一小块硬件区域，并不是显卡的主要功能

    理论上来说，你的配置下完成2-3速度的场景应该是高分辨率编码，比如4K或8K，但你给的预设码率是3800，大约是108P的水平
