CPU usage question...

Community
#1

Why does ZBrush use 99% of my CPU when idle?

This doesn’t seem right at all. (It’s not necessarily causing any trouble,just seems REALLY weird.

Hi Kat . . .

What do you mean by “99% of my CPU”? :qu:

I have ZBrush open right now, while I’m on the internet with Explorer 5.5 open, & I’m still showing 265 mgs. ram free, out of 512 mgs. :rolleyes:

I’m probably missing something, but how do you display your CPU usage??? DUHHHHH! :o

Have a good one . . . Not too swift today :cool: Mark.

Here’s what I mean

This shouldn’t be happening. But I can’t figure out why it is…

If you go to the applications tab, you would see that ZBrush is taking 99% of that 100%. It was sitting idle when I took that screenshot.

I have Outlook open as well. Of course there are other little ditties running behind the scene (thanks MS!!).

Anyone have any thoughts???

Hi again Kat . . .

I’m running Windows 98SE, & I don’t have the tool you have on your operating system, I did a lengthy search for it with “0” results. Also, I’m ashamed to admit it, but I can’t even find a tool on my whole system, to find out what my “CPU” usage is??? :o

Anyway, I’m sorry I can’t help you with your problem. The only thing I can say is, that I agree with you in, you should not be seeing 100% system usage while ZBrush is in an idle state. :wink:

Good luck in solving the problem & have a good one . . . :cool: Mark.

PS: Hopefully, someone who has the knowledge for this will comment on & answer this question?

Thanks for the time Kruzr.

I’m hoping ZuZu or one of the other greats will peruse the posts and give me an idea as to what I’m facing here…

I really believe it’s half my problem with Photoshop (although, I recently found out P6 has some serious problems with Win2000, but they (adobe) blame it on hardware…which I say, is BULLS#($.

ANYWAY, thanks for the concern.

I’ve never run your OS, but I get my little manager at Ctrl/Alt/Delete, T, them blam! there’s my manager. I do believe this particular interface is Win2000 specific.

But thanks again for your time. I really do appreciate it.

The task manager shown looks like the same one from Windows NT, which mekes sense considering Win2K’s origin. I have not found a built in manager for Win95/98, but you can find many tools on the web that might help. I like going to moochers. Everthing there is free, so try what you like. Careful for the stuff marked as Adware, also known as spyware. Of course, not all of it is marked as such, so you have to do some research.

Kathy, I can’t give any insite on your issue, but as soon as I got ZBrush back up and running, I will see what I can find out, if anything… :rolleyes:

#7

Cool, thanks Kaz.

My hubby is at a lose, and that’s saying alot.

But hey, it’s working well and I’m getting alot done, so no complaints, just curious…

Hi Kathy,

We’re looking into this.

Thanks ZuZu!! I appreciate it.

Hi again Kat . . . :slight_smile:

I found a program "Free Meter" on ZDNet & installed it earlier. I think I can say that it's not your system at all or the operating system either. Soon after installing it, with all the meters showing, I opened ZBrush 1.23 - Bingo - my "CPU usage" Immediately jumped into the RED at ( 100% ). So this is something that Pixolator is going to have to look into. ;) I just wanted you to know it wasn't confined to your system or Windows 2000, or Windows 98SE. :D

See’ya a little later . . . :cool: Mark.

#11

Thanks Mark. I figured as much.

Cal just went out into the world and bought me over 700 Mgs of RAM…so DAMN the torpedos!!
BWAHAHAHA!

Do you like that Free Meter? (Heard it was very acceptable)

#12

Hi Kat . . . :slight_smile:

I just found it today, due to the fact that there's nothing in Windows 98SE, to do what I wanted. I've been messing with it for about ½ hour now & I really like it so far. Here's the link to the developers site & to download it -

( http://www.tiler.com/freemeter/ ).

I've got to tell you something though, while I was playing around with it to see what kind of CPU usage all my other programs were using, I fired up ZBrush 1.13 & to my surprise, it immediately drained my CPU usage also, 100%, so this is something that is not new to version 1.23. I'll send ZuZu an e-mail regarding this. ;)

See’ya later . . . :cool: Mark.

#13

hmmmmm. Interesting…

What’s it all mean alphie??? (OH god, I dated myself again)

Thanks for the link!

#14

You don’t have to apologize all the time Kat, I know a lot of people who would love to be “DATED” as much as you lately!!! Heheh. :smiley: :smiley: :smiley: :smiley: :smiley:

#15

HA!

That’s a good one. :smiley: :smiley: :smiley: :smiley:

“Dated all the time”…snicker…you crack me up.

Hi guys. Sorry to butt-in. Being a ZBrush user since version 1.03, (or version 0.95?? so long ago now!) I recall ZBrush use to crash a lot. When version 1.03 came out this was solved but the CPU usage hit the ceiling! I’m afraid I can’t answer your question, but draw the conclusion that high CPU usage = less crashing, or Zbrush is just ahead of it’s time, and was programed by Ofer-the-time-traveler who travels back in time to release ZBrush on our wimpy computers! (I think the first conculsion is more plauseable)

Kathy, a 100% usage of your CPU means only that it works with 100% efficiency at the moment-all CPU resources work for ZBR. If wou run other application Windows will keep a part of this CPU time for ZBR and the other remains for the new task.If ZBR use less than 100% of your CPU it will work slowly-you don’t want that?!For instance I usually run both ZBR and Photoshop and the difference between ZBR or ZBR&Photoshop isn’t so big(no need to switch on\off PShop every time I need it) I have AMDThuderburd 900 MHz + 320 100MHz RAM. Think that in your case this CPU info is useless.In fact if you move your mouse cursor quickly on the screen the CPU usage is getting higher. By the way have you ever seen indication for how much time you must wait(for example:1min) to finish the trasfer of data in Windows? And after 10 minutes you see the same thing? Windows is stupid software for users.

My CPU usage shows the same. Runs at 100% when idle with Zbrush open. I have other 3D software that does the same so I ignored it. It would be nice if it wasn’t running so high. I don’t run anything else while I’m zbrushing because of it.

However, I did notice something really cool while I was watching my CPU usage and that is … the Physical Memory i.e., Available and System Cache are cleaned up by ZBrush. In other words I have some software that loads up the cache and when I close the software the memory is not released. However, when I notice it getting out of hand I open up ZBrush and work for a little bit, close ZBrush and all my cache is returned for use. :smiley:

Not sure why it happens but it does and I like it!

#19

Oh, people,
this W2K task manager shows a 100% usage of CPU even during program installation! This is some kind of stupid-o-meter, “Oh, Dexter, what does this button do?”.

#20

Martin,

Since when do the TranslateMessage and the DispatchMessage calls to the Win32 API make the CPU usage for the application that calls them go to 100%?

The typical reason to see such CPU usage is from a loop that normally does not need to be coded the way that it is. The only “application” that should even consume close to 100% of the usage during idle is the “system idle process”.

This is the whole reason the process of 100% usage all of the time, even while static, is uncalled for.

Somewhat like squeeky brakes on a car. It doesn’t necessarily do anything bad or indicate anything WRONG with the car persay, BUT it just shouldn’t be happening.
