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?

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...

lol welcome to the forums, Impulse - this post sounds rather familiar

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).

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..

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

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.

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.

Here is the logfile, it's chinese to me though

Were you able to make anything out of it?

Wow, whad'ya know. It actually helped!

Oh and you have a 'leet' post count now eh eh

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.

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.

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!
