Need some help for cpu time control ...

[marc_256]

Hello everyone,

I'm using a 3D modeling program,
no, I'm using 3x 3D modeling programs at the same time.

When I'm minimizing the programs, one of them is still using 33% of my cpu time.
so when I'm rendering I lose a lot of cpu time and have to close the program and start it up after rendering is done.
I do this about 20 times a day, so

When I ask about it at the software developer, they can not give me an answer for that problem.

I payed a lot for it, so I like to use it.

Q)
Is there a way to find out what this software is doing while minimized ?
? Internet connections
? mouse
? keyboard
? memory


I use:
PC
WIN XP pro - SP3


Thanks,
Marc,

Since it's using 33% of your cpu with 3 programs opened it's practically going 100%.
Well I mean if the other two are maximized, not sure from your sentence.

So I guess it's rendering at full speed even when minimized.
The developer should put a check and skip all unneeded activity when minimized to resume it when restored.

You can try to lower its priority below the one of the other twos.

Since it's a graphical program (opengl?) you could also try to force vsync enabled in the drivers of your graphic card to limit the rendering speed. But probably the software already do that unless your drivers are ignoring the request.

Hi luis,

Since it's using 33% of your cpu with 3 programs opened it's practically going 100%.
Well I mean if the other two are maximized, not sure from your sentence.

Even when the other two are minimized it still take +-30% of the cpu time.
Even when I'm not rendering.

You can try to lower its priority below the one of the other twos.

I can try this ... (this after noon)

I did some tests with second PC.
Intel - P IV
Win XP pro - SP3
Same software
same anti virus
And works OK there.
Only with AMD (Athlon XP) cpu's I have the problems ??@#%&


Thanks,

You could try a software i wrote. It's meant to slow down games that run to fast on modern CPU's.

All other programs that do this, grap CPU time to slow down the whole system. My program only slows down a specific process and actualy frees CPU time. I never got it to work 100% accurate but it might help you with your problem.

Extract both the .exe and .dll.
Start the .exe and double click on a process in the list. Use the slider to adjust the slow down.
You might need to start it with admin rights.
