Hangouts over taxes just about any machine, it's ridiculous. FCP exporting a 4k video uses less CPU than Hangouts does to show a choppy video feed.

Are you using Chrome? Apparently under Safari Hangout uses much less CPU.

I guarantee it doesn't. Hangouts in Safari will peg my CPU near the thermal limit for the duration of the call.

Hangouts is awful in general...it heats up even very powerful computers in the process of showing pixellated, glitchy video with distorted audio, even over a very low latency 200 megabit connection. We use it every day for work and its a source of constant frustration. Honestly I'd prefer a conference call on a landline, we have the video off most of the time anyway because it seems to cause more audio dropouts when…

I have this issue with linux and I was wondering if it was hangouts (really, the old "GoogleTalkPlugin") on linux that was the issue. Is this on Windows you have these issues?

I had the original rMBP, now the 2014 one, and don't see the same problem. A lot of it is in the persistent services that are running on the machine; I'd take a good look at Activity Monitor's "energy" pane. One thing I noticed: if you're using Chrome and have persistent pages open (cough, GMail, cough), this is probably a big part of your general heat issues. It made me go back to Firefox for a while, but Firefox's…

Safari handles those cases like a pro.

It does! Safari is much better at battery life. But, for my use cases, it's an unusably poor browser outside of its rendering engine. My extensions don't work within it, I can't easily find equivalents, and there's no easy, good way to sync between Safari and browsers on Windows (Xmarks hosed my bookmarks so badly that I haven't yet even fixed all of them).

turn off HD quality and it stops using the VP8 codec (no hardware acceleration) and drops back to H264 which is hardware accelerated. My cpu usage goes from 80% to less than 20%.

Notice this is coming from a user who did not even use a task monitor first. He writes in a followup post that he had a task maxing his CPU on the background.

Every system should come with a simple task monitor installed and running in a visible place, e.g. an icon in the Mac menu bar. Yes I know about the Activity Monitor - it's not enough.

It's basically like being sold a car without the engine oil temperature gauge.

I use hangouts daily and unless I'm on a high end PC I switch to audio only to avoid the jet turbine effect. They really need to optimize.

Video encoding is expensive. You get to pick between more CPU usage or worse video quality.

It's probably similar to the fullscreen problems Adobe Flash had in the past, where the CPU was being used to resize tiny video to fullscreen resolution. This lead to low definition video becoming choppy while pegging your CPU at 100%.

Playing the same video fullscreen in something like Media Player Classic would result in negligible CPU usage since it wasn't going through Flash's 2D engine + software scaler, and instead your video card would handle the scaling with ease.

Hardware scaling using overlays is very old technology, so it was kind of sad that from mid to late 2000s, internet video was being hampered by poor software scaling.

This seems highly doubtful. They are both Google's code - one is just packaged as a plugin rather than built into Chrome.

Browser-specific performance quirks has been the name of the game since forever.

Activity Monitor allows you to switch out its static icon to a dynamic CPU Usage gauge on the dock.

View -> Dock Icon -> *

* CPU Usage

* CPU History

* Network Usage

* Disk Activity

The 'garbled microphone input' seems a bit of a red herring, it's likely that the thermal throttling is kicking in which is causing the audio recording app to get slowed to below real time making it sound like garbled. I've had the laptop for about a month now, and yes, Hangouts will bring it to its knees, but for some reason Hangouts will bring just about any laptop to its knees. Battery life is as advertised, you d…

>yes, Hangouts will bring it to its knees, but for some reason Hangouts will bring just about any laptop to its knees.

I've got a couple year old x1 carbon 13", and it handles hangouts fine, more or less everyday. That's with the (annoyingly high) cpu usage of a couple hundred tabs open as well. If a tiny couple pound ultrabook van easily handle hangouts, I highly doubt that hangouts would be difficult on most laptops (let alone "just about any").

The 15" rMBP will apparently throttle if you load the CPU + discrete GPU at the same time. That said, I have no use for GPU, and I've been pretty impressed by how cool it stays given the thin profile and quad-core CPU.

Do the fans stay at a pretty consistent level, or do they throttle a lot from quiet to noisy? I'm thinking of getting one, but the people I know who have them tend to use them in noisy environments and can't answer my questions.

The only time I really notice the fans is when I'm running a website in debug mode in visual studio. Note I have no issues with running a vm in VMware Fusion all day, or with using visual studio in it. Which I assume is a fairly high base level load.
