And that is only the main process. I have 4 additional processes running

What shell are you using with Hyper? (Options: cmd - default, powershell, native bash, maybe others I don't know). Are you using plugins? Try to disable them if you do and report back.

I have made no changes to default settings of Hyper. So it use cmd as shell and no plugins at all.

Also experiencing this, though it is more pronounced when I get into zsh going up to about 7% usage

I also experienced, and also just the default experience. Made it unusable, had to close it and stop using. I will wait for a later release.

Just updated to 1.3.0 and CPU utilization is still quite high. About 30% constantly across the 4 processes. Also Windows 10 build 14393. I'm using Powershell.exe. My Config.

FWIW, after letting the window site idle for a couple of hours, I found CPU utilization to be near 0. I don't know really how long. That and JS profiling shows nothing leads me to believe it's some background task that eventually finishes or times out.

And I let it sit overnight and it's still using 30%+ CPU this morning. /shrug

This also happens to me on Win 10 build 1607, but only when I install hyper-tabs-enhanced. As soon as I remove it, CPU usage goes back to normal. Curiously, the Desktop Window Manager also cranks up at the same time.

@cdhunt Can you try with a vanilla HyperApp. Without any (hyper-tabs-enhanced) plugin?

I was just testing and I can corroborate disabling hyper-tabs-enhanced reduces CPU usage to ~0%.

Great!
So we can close this issue (other feedbacks are old).

But feel free to reopen if last version of Hyper has a high CPU usage without any plugin.
