Hi all,

On a near-daily basis my Photoshop appears to be running on only one of my cpu's four cores. I can't explain it... I do not have affinity set for Photoshop, and it is causing my cpu to nearly overheat by pushing that core's usage to 100% until I close the program.

Closing and reopening Photoshop will sometimes cause it to run normally across all four cores, and other times it will push its self back onto just the one. So far I have only noticed it doing this on core 4, the other three are running at the normal 10-20% usage. It seems to just be this computer as well, no one else in the office or my computer at home does not experience this anomaly.

I have checked the process when the core was at 100% usage and Photoshop.exe was set to all cores, not just core 4. Does anyone else experience this? Is there any reason for it or any way I can fix it?

hi,
always a good idea to give system specs.... cpu speed, ram, what OS, photoshop version, etc etc... when discussing system type problmes that one that always looked at...

i am going to first approach the issue as a system issue , and that thing are slow..... this is where knowing stats of the system could help...

but are we sure there no infections?
also try disableing all startupand see if there a improvment...

also take a look at what activity you have on the networks?

sometimes just doing a defrag helps ....

when look at the task manager cpu history... what does cpu performance show.... generally that should be very small(less than 5%) when your not doing anything..
now under the resource monitor..

cpu tab ... normal to see some of the cores parked.. the thing i don't knowfor if core 4 is the primary core or not ... i need to look into that...
on my system i7 win7 64 bits, lots ofram ...
everything islow and a few of the cores are parked

now under overview,cpu show shows very small activity what does your shows... ?

in fact right now, my system the ony things that show any significance is my netowrking and disk activity and that sort of normal .

found this one thread.... sort of sounds similar to your issue... however!!!!!! there remdy is to make a change in the registry... and to me that a very last resort.... you check out things first.... and alsoif you do... see what you have to do to restore if it turn out the change doesn't work .. smiling

Windows 7 home premium (64 bit)
8gb ram
AMD Phenom II X 4 965 3.4 ghz processor
Nvidia GeForce GS 250 graphics card

running Photoshop cs4 64 bit with openGL enabled. it is not a low-end system, and does not have any performance issues other than this one strange snag.

very little on startup, network activity is at a bare minimum, no viruses, defrags on a regular basis, no registry issues were associated with Photoshop. My idling cpu usage with Photoshop closed is 5-10% across all cores (I have background applications running at all times). With Photoshop up and NOT using 100% of core four, all cores are at 20-30%

hi,

hi,
ok.. a couple of things first...
100% on all cores... are any of them "parked" when parked they show 100% but they will be greyed which means there not being used...

next that 5-10% to me is high... it definitely should below 5% and in fact somewhere between 0-3% where most of the time it at 0%!!! ... with my system it around 0% vast majority of time..

and with photoshop open and cpu is at 20-30% again that is to high... withmy system with it open and idle, she jumps around alittle but it only between 0-3% , i can only think that your photoshop is maybe still trying to load up or there a issue with division of ram and it having togo to the hard drive a lot...

now some thoughts what to look for..
1. opengl,,
A. does your graphic card support opengl and shader!!!! if it does not then uncheck the ps opengl setting...

B. if it support open gl then check the graphic card setting and see if it checkmarkd .. Iknow on my system when i got it.. the graphic card setting turned off by default....

2. now in your task manager .. it probably be best at this time to have photo shop closed...for now.... but take a look at your processes tab and see which one of those process is using up 5-10% ...
note: if you leave ps open probably it would tell that it using up to 10-20% .. just a educated guess..

3. go to your msconfig>startup and disable all startups , click ok and reboot and then see what your task manager cpu numbers are... if there down near zero... then you know it was one of those startup ... and it a tedius task to try to narrow it down which one or two the culprit...

4. now in generally things will give high number for cpu activity...
a. of course malware but you said that clean...
b. some program is constantly check backing tohome base maybe checking for updates/patches or what ever..... programs like av scanners, firewalls, maybe even photoshop etc... so take look at those programs that do autochecks ...
c. might look at your event logs... and see what excessive activity and also any fail and any excessive failures..

c. might look at your event logs... and see if any excessive activity and also any fail and any excessive failures..
note: windows logs>applications not unusal to have a couple of warning.. butmyself i look for constant reptitious problems ... the other logs in in the window groups should be nice and clean ...

performance issue can be very time consumming to track down ... and requires patience...
