各位 mac 用 Razer Core X eGPU 的 v 友,你们的 chrome 有被 eGPU 硬件加速吗?

我用的是 RX 5700XT, 平时跑其他程序都在顺利使用. 也已经指定 chrome 的 app 优先使用 external eGPU,但是从内置的 active monitor 里看,google chrome helper(GPU)进程是始终在内置的 Iris plus Graphics 655(Built-In) 上活跃,而不是在 RX 5700XT 上. 这是哪里设置不对吗?

youthfire OP 自己先来一个找到的解决方案:
盒盖使用 mbp 来源如下: I had the exact same issue. The problem is that Chrome is defaulting to using the integrated GPU instead of using the eGPU. For some reason, if the integrated GPU has a connected active display, Chrome will always prefer this instead of any eGPU. You can observe this by going to chrome://gpu and seeing the available GPUs, and that Chrome has selected the integrated GPU. The solution for this is stupidly simple, but annoying that there isn't a Chrome config to avoid this. The solution is to just shut the lid of the laptop when using an external display. This puts the laptop into "clamshell mode" which effectively "unplugs" the internal laptop display. Once this is done, starting Chrome will result in it selecting the next GPU with an active display, which will be the eGPU. Check chrome://gpu to see if this is the case. Once Chrome has started, you can re-open the laptop lid, and Chrome will continue to use the eGPU even with the internal display being active. Unfortunately if you are using a setup with a machine using purge-nvda, then clamshell mode is broken. This was the case for me and I was stuck using laggy Chrome. I just recently tried using a fix for clamshell mode when using purge-nvda, discussed here: https://egpu.io/forums/builds/MacBook-pro-15-retina-mid-2012-razer-core-x-with-rx-580-and-functional-sleeping-waking-up-and-brightness-control/ I followed the instructions on that build to fix clamshell mode, which worked and as a result I now have Chrome using the eGPU and have a super smooth experience. 如果可以不盒盖的方案来关闭内置显示器,请帮忙补充 |

我看了一下 chrome://gpu，的确给的是集显。 活动监视器里面 google chrome helper (gpu)，如果打开 requires high perf gpu 一列，写的是 yes 实际使用中，显示器直连显卡盒子，在显示器上看 chrome 视频，看到的显卡活动在 eGPU 上。如果把窗口拖到笔记本内置显示器，活动就是集显了。 |

可能是自己太笨了，因为解决不了这个问题，Razer Core X eGPU 和里面的 5700xt 已经被我丢到一旁落灰去了～

youthfire OP @IgniteWhite google chrome helper 在内置显卡和 egpu 端都有进程,我测下来,只要开盖使用,活跃在集成显卡上,只有盒盖才能跑在 egpu 上,chrome://gpu 内会显示如下信息:
GL_VENDOR ATI Technologies Inc. GL_RENDERER AMD Radeon RX 5700 XT OpenGL Engine @bingheath 闲置的话就太浪费啦,你是习惯了开盖用么?其实我也一直是,一直到发现这个问题去买了键盘和立式托架 |

@youthfire 我确实是习惯开盖用，毕竟多一个屏幕，而且 chrome 里好多选项卡开着。 我实在不敢合盖用，我的是 16 寸 i9 的 mbp，那惊人的发热我怕把屏幕烤化～
