前段时间仿照MacMini低配装了台机子,相关测试下来性能跟白果相仿,升级到Big Sur后测试了一下核显的硬解,发现GPU频率被限制在0.33GHz,跑Cinebench R15 GPU部分频率是可以跑满。在论坛翻贴想找到解决办法,终于看到坛友angeltangdai回复别的坛友时的提示,说WhateverGreen从1.42起禁用了RPS Control Path,要开启需要添加igfxrpsc=1,添加到启动项果然起效。下面是WhateverGreen 1.42的更新说明:v1.4.2- Fixed disable-external-gpu (-wegnoegpu) on some systems
- Disabled RPS control patch by default due to a bug in 10.15.6 IGPU drivers
- Replaced igfxnorpsc=1 with igfxrpsc=1 to opt-in RPS control patch
- Support all valid Core Display Clock (CDCLK) frequencies to avoid the kernel panic of "Unsupported CD clock decimal frequency" on Intel ICL platforms. (by [color=var(--color-text-primary)]@0xFireWolf
)Fix the kernel panic caused by an incorrectly calculated amount of DVMT pre-allocated memory on Intel ICL platforms. (by [color=var(--color-text-primary)]@0xFireWolf)
添加igfxrpsc=1后运行intel Power Gadget的截图
没有添加igfxrpsc=1前GFX REQ显示0.33GHz
手头上只要i3 8100,遇到类似问题的朋友可以自己尝试,看看是否管用。
