And as far as your quad core, i'm pretty sure it's using 25% of a single core or about 6.25 of all 4 cores. Still not good, but perhaps not as bad as you previously thought.
Well I doubt 25% of my overall cpu being used is equivalent to 25% of one core. As I stated before, I have 4 cores, so no matter which way you look at it, I'm losing the equivalent of one core overall, whether or not it is divided up among my other cores makes no difference in terms of performance. (or at least very little)

Even if it isn't as bad as it looks, the steam client shouldn't be anymore demanding as Safari...

I started another thread to explain the cpu confusion- you're not the only one having it.

if activity monitor is showing steam at 25% CPU, that means 25% of one core, not 25% of your overall CPU power. If you have a quad core, that means ~6% of your overall CPU power. It's still too high, but it's less ridiculous than maxing out a whole core. Steam does a bit more than safari, and it has to maintain a constant connection because it does IM and some other things in addition to being a browser, but it should be idling under or around 1-2% of one core regardless. It's about 1 order of magnitude too expensive on the CPU.

Okay, I wasn't aware of that. I'll keep that in mind.

I don't think I've noticed any of my games reaching above 100% cpu usage which is why I assumed it was for overall cpu.

I'm shocked that source games don't use more than one of my cores...

Putting that in perspective, should steam even be in the ballpark of 1/4 as demanding as Portal? No, no way.

I guess I'll weigh in on this, too.

I'm using a Macbook Pro 2011 with quad-core i7 and sitting at 20-24%, basically maxing out one core, on idle.
This is a killer for battery life, game performance, and whole-system performance.
I've seen malware that has less detrimental effects than the current version of Steam does.

For a product I've put so much money into, this in inexcusable.
Valve made a big promise to Mac-owning gamers when they committed to OSX as a platform.
I remember how exciting it was for Macs to adopt Intel processors and then for Steam to finally run on Macs; it looked like Mac gaming was poised for a return to the golden days when it defined the PC game market.

However, this apparently was a nothing more than a sloppy gesture by Valve to squeeze a few bucks out of us without actually delivering on performance or support.
The selection of games has been sparse. I'll give them some kudos for releasing their 1st party games duel-platform, but when compared to, say, Blizzard, and even some 3rd party ports, there's a huge performance disparity between the Windows and OSX versions.
Furthermore, I can go find plenty of Mac games elsewhere and, when I check Steam, the same games are Windows-only.

I sincerely hope Valve reconsiders it's stance on the Macintosh platform.
I think there's good money to made from the ever-expanding Mac user base, many of whom would like to stay as far away from Windows as possible, rather than restart into Bootcamp anytime they want to get their game on.

I have one core AMD Sempron 2200+ 1,5GHz and i have big computer lags when I use Steam. I have really problem with lags.

Amen to that.

But according to masterchef341 from a few posts above, that 20% cpu usage is out of 400%.

correct, mac counts each core as 100%

indeed. 25% CPU in activity monitor for steam means 25% of one core, not 25% of your overall CPU power. It's not maxing out a core.

Although I agree that you guys all have issues... QUIT THE DAMN CLIENT instead of leaving it idle. Im sure that valve are aware of the issue

Obviously you need the client in order to play games. I shouldn't have to quit the client every time I launch one of my games.

As stated, you have to have the client running in order to play any games, as well as using desktop client features, like chat, voice, etc.

Mine hangs around 10-12% (Mac Pro 3.33 ghz 6-core) Lion 10.7.3
Same on my Macbook Pro 2.8 ghz 2-core. Kills battery life and heats it up a good 10˚C.

Adium is the closest in terms of idle CPU usage and it idles at 2.3%

What's Steam doing constantly that requires it to crunch numbers like that?

The Steam Mac client is trying to figure out a way to make our gaming experience even worse... (there is a lot of number crunching involved to figure that out)

>Quitting the client
