CPU usage

Hello, I recently bought a 2nd display (24" LCD to complement my 19" CRT) and I've been trying out the UltraMon and DisplayFusion trials. It's not taboo to mention the competition is it? :P

So far I actually like DF better overall, it seems a lil' more polished... UM is more tweakable in some regards but most of it is common sense stuff that DF does by default, I like the way DF handles wallpaper much better (lots more options for randomization, etc, gotta do all that via a script on UM), and I like some of the extra windows positioning hotkeys... Though there's two mouse hotkeys in UM that I'd love to see in DF (move mouse to 2nd display and center mouse on-screen).

Anyway, I'm about to plunk down the cash for two DF licenses but there's just one thing that concerns me... DF seems to use more resources than UM, CPU utilization on UM is usually at 0% and it switches wallpapers pretty quickly, DF seems to take longer (doesn't really concern me) and I notice CPU utilization is always bouncing between 0% and 3%. I suppose it's not a big worry with today's quad cores and such, but I wanted to know if this is normal behavior or if there was something funky happening on my end...

What I describe only happens with the extended taskbar enabled so it's gotta be related to that I guess. For what its' worth, I think DF does use less RAM overall than UM (which runs three separate process if you use the script to switch wallpapers automatically).

I tried to do a bit of searching on the topic but came up empty...

The CPU usage is probably related to the polling that DisplayFusion does to keep the 2nd taskbar updated. Lowering the CPU usage is something I will be trying to tackle in the next release. I'm glad to hear that you're enjoying DisplayFusion overall, and I hope to drop the usage into the 0%-1% range with the next release. Thanks!

Cool, thanks for the prompt answer. I'll be purchasing a DF license (or two) soon, it's nice to know you're still actively working on it so much ('specially with W7 comin). :-D

I've been pouring a ton of time into DisplayFusion lately, mostly because of the new 3.0 release. A few bugs were discovered after releasing it (as with any software) so I've been working to clear them all up. Windows 7 has added an extra challenge to the process as well. The Windows 7 taskbar is so radically different from XP/Vista that it has been interesting trying to interact with it. :)

Well the 3% cpu usages is a bit low ... for me it can go up to 24% which when playing games or vids with zoomplayer can cause trouble.

This happens when i have enabled taskbars on all desktops.
On a dual core it can be troubling..

Version 3.0.4 contains more improvements for the CPU usage. :)

Lately DF is making my OS lag like hell, I don't know why though.

@rpsgc: Does it seem to happen more frequently when certain applications are open? Does it happen when the DisplayFusion taskbar is turned off?

It happens especially when I'm installing new software. I have to test it further but I don't think it happens with the taskbar turned off.

This on Vista x64.

I can say that I get 45/50% CPU load (for DF's process only) when I'm using a virtual machine and it lags both my OS and the VM's OS. However if I shutdown DF and run it again everything gets back to normal.

@rpsgc: Can you go into the DisplayFusion settings window, and enable "Debug Logging" on the Troubleshooting tab? Let it run for a few days, and after you start experiencing lag can you send me the log file? I would like to see what is causing the poor performance. Thanks!

Where is the log located? I click "open log location" but it doesn't do anything.

I also notice some cpu spikes when I'm extracting a large archive file (rar or zip) for instance.

The DisplayFusion log is located in the same place as the downloaded images. On Windows XP this would be:
C:\Documents and Settings\[username]\My Documents\My Pictures\DisplayFusion\DisplayFusion.log

Were you able to make anything out of it?

Thank you - I reviewed it and made some changes for the next version to try and reduce the CPU usage.

Unfortunately version 3.0.4 apparently makes it worse. The high CPU usage remains but now instead of slight "hiccups" the whole system micro-freezes for a few seconds (can't move mouse,etc) when I'm installing something, running a VM or any more intensive task. Sometimes also when I'm gaming.

I've also noticed this too since I began using DisplayFusion (3.0) with the mouse freezing or lagging when doing something heavy. I'll try and take note of what I'm doing when this happens.

Strange... If I close DF and then start it again it seems that the freezing/lagging issues are gone. I'll have to test it some more.

Yup. I tested it and it's true. If I close DF and start it again those freezing issues are gone.

I have made some significant improvements regarding CPU usage in the upcoming version 3.0.5. If you would like to test it out please send me a PM. Thanks!

This has been bugging me for weeks! Using Outlook 2007 on Exchange, if I click a new message I haven't read yet I would get a breif moment of mouse lag whilst it loads the page. Or playing Sims 3 my wife would complain of mouse lag for up to 5 seconds, yet the game is still running fine in the background, she just can't move the mouse when she clicks on her Sim sometimes.

However, today the free trial of Displayfusion ended, so I exit'd the application and the problems disappeared! I never for the life of me thought it would be this causing the issue. If I'd of had enough free time over the last few weeks I would of re-installed Windows as it was driving me crazy.

Meanwhile though, Displayfusion has otherwise performed tremendously and I shall be purchasing Pro tomorrow morning, in the hope that the "significant CPU usage reductions" will remove the mouse lag.

The next version (3.1) will completely unload any system hooks (including the mouse hook) when a game is detected, so this should help with the Sim 3 issue for sure. It also includes some other performance improvements, which should help general applications as well (like less frequent and less intensive taskbar polling). :)

Thats great to hear. In the meantime I can satisfy the wife by training her to close DF before she loads Sims 3.

PS. The latest news item at http://www.binaryfortress.com/2009/06/displayfusion-306-released/ reads as "I am very announce the release of DisplayFusion 3.0.6!". May want to add "happy to" to that sentence :)

Hmm... I thought that problem was gone but yesterday when I first played Crysis I noticed it too. The game would freeze for a couple of seconds every 5/7 seconds. I turned off DF and the problem disappeared. And I'm using Prevent System Hooks!

I can report a 90% improvement on mouse-lag with v3.0.6. I no longer notice mouse-lag in Outlook 2007. Haven't used the PC enough to give a thorough test, but Sims 3 is almost trouble free although it does happen once in a while, not nearly as frequent as it once did. Wife can now use Sims 3 with DF active without nagging, so must be good!
