Hyper: Why does Hyper force dGPU (2018 MBP)

[mtslzr]

• [x ] I am on the latest Hyper.app version
• [x ] I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: macOS 10.14.5 (2018 15" MBP)
• Hyper.app version: 3.0.2
• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/mtslzr/a8843911e48dcbdcce6285ee4cb6a8c5
• Relevant information from devtools _(CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere)_: N/A
• The issue is reproducible in vanilla Hyper.app: Yes. Tried disabling all plugins, and issue persists.

Issue

Was wondering why Hyper.app requires the dGPU on my 15" MBP? And is there a way to disable it? Scoured a few older issues, but most seemed to talk about external GPUs, and I didn't see an obvious solution.

Same here. Impossible to switch to integrated graphics mode which means battery is being drained.
"Hyper Helper" is using the GPU. Please allow a toggle in the config file.

Same issue. Also macOS 10.14.5 (2018 15" MBP). Neither Terminal.app nor iTerm.app need the dGPU. It would be great if Hyper would follow suit. I've got Atom/Eclipse/TablePlus/GitHub Desktop/Safari/Parallels all open at once... but only Hyper.app is triggering discrete graphics.

When the dGPU turns on, it causes the "cursor flicker" bug in macOS that's existed for years when it changes states (e.g. hovering over a link) which is really annoying 😬

I prefer using integrated graphics at all times

I just find out the solution. Disable the new WebGLRenderer in config with: webGLRenderer: false
It will switch back to the Hyper 2's canvas based renderer and the system will switch back to integrated GPU. :)

Thank you!

That was driving me crazy! I was just about to give up looking for a solution when I found this!

How do you guys know the discrete graphic card is activated? I use the _gfxCardStatus_ app - but curious what apps/tools you guys use?

[mtslzr]

@saamalik Open Activity Monitor and go to Energy. There’s a column for which GPU each program is using, and at the bottom lets you k ow if your machine is using iGPU or dGPU currently.

This is a problem for sure - as I understand, there's some sort of flag within electron to specify which GPU to use. I don't think there's an issue with using the new renderer on the integrated graphics, it just needs to be configured correctly. This is the only electron-based application I've seen that has this problem.

[fsegouin]

Any real reason for the new WebGLRenderer to use the dGPU? I can't see any difference at all when disabling it.

[saamalik]

@fsegouin a few months ago, on my 2017 MacBook Pro - I noticed a significant performance difference when operating Hyper in fullscreen mode.

However, (un?)fortunately I got the new 2019 MacBook Pro and not able to reproduce the issue now. Not sure if it's because the laptop is just screaming fast or if hyper/xtermjs changes improved non-webgl performance.

Having the same issue. I tried setting webGLRenderer: false but it doesn't seem to solve the issue. I always have the dependency on Hyper Helper which prevents from using the internal graphics card and which is killing battery life when on the road. Using Hyper 3.0.2 and also tested it with the latest 3.0.2-canary.4

EDIT: Seems I did something wrong. Disabling the webGLRenderer indeed removes the dependency to the GPU and runs on the internal gpu.

[NozzyEz]

yes, disabling webGLRenderer worked fine, just had to restart the app

Doesn't work on latest canary

[saamalik]

Interesting, on my system the canary build is not using the discrete
graphics card - even if I remove the webGLRenderer option

Similar issue for me:

Hyper Helper shows "Graphics Card: yes"

Hyper 3.0.2 (stable)

MacBook Pro (Retina, 15-inch, Late 2013)
macOS Catalina 10.15.4

Can confirm suggestion above to add webGLRenderer: false to config worked, thank you 🙏 .

[bogdancss]

any feedback from zeit on this?

[lyndsysimon]

This is important to me as well - it makes a _huge_ difference in terms of battery life.
