Avid Media Composer用游戏显卡加速.doc

Avid Media Composer 5.5.2 可以使用 游戏用显卡 进行加速，通过测试效果提升显著。

在AVID MC 的安装目录里找到 Avid\Avid Media Composer\SupportingFiles\Config 这个目录，用记事本打开  QualifiedGpuBoards 文本文档：

这是AVID MC 5.5.2 版本的 QualifiedGpuBoards 文件，

把自己电脑里的显卡的   完整名称 ， 厂商名称  ，型号字符串，以及电脑安装的显卡驱动版本 添加到这个文本稳当里，比如我的显卡是

GeForce GTX 460 ，我安装的驱动版本是 275.33  ，就修改成下面的样，

即可。

附修改前后的测试，

这是本人的 GeForce GTX 460 测试，红线为添加的显卡信息。没有测试过其他型号显卡。

另外：
费米显卡( GTX  460 .470 . 580 .560TI. 450 等 fermi 核心 DX 11 的 NVIDIA 显卡） 性能比较出色的，并且有节能功能，在不需要太高的 GPU 显示性能的时显卡会自动降低 核心.显存.流处理器的速度，以达到降温节能的作用，在需要 GPU较高性能的时候会自动全速运行，当运行 MC 软件的时候会出现显卡节能低速运行，可以通过在 NVIDIA 的驱动控制面板 3D 设置里开启电源管理的高性能选项, 强制运行 MC 的时候 显卡 GPU 全速运行，附图 ：

这样在 运行 MC  软件的时候显卡 就会以高性能 运行了，其他支持 GPU 加速的软件可以用同样的方法，比如 AVID FX 5.8.3
