Was it just the audio driver, or the the Realtek helper app that seemed to be causing it? ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#25 Fri, 12 Jun 2015 21:28:26 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#25 DisplayFusion Sorry to take so long getting back.

Issue has not returned since getting rid of the sound card application, which I never used anyway, so I'm satisfied, but if you want to RCA it, I'm willing to provide logs in case there is a bug. ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#24 Tue, 21 Apr 2015 13:01:54 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#24 DisplayFusion Also, we've just posted 7.2 Beta 4. Could you give it a try, and if you still have this issue, attach a new debug log?

Thanks! ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#23 Wed, 01 Apr 2015 14:23:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#23 DisplayFusion Wow, that's really strange!

For some reason, while DF is running, my Sound Driver application (not the driver itself) starts churning out SeCreateGlobalPrivilege requests and failing.
So, here is how everything stands

Everything works normally without DF
With DF, CPU pegs, DF hammers the event logs
With DF running as Admin, My sound application hammers the event logs
With DF running as Admin and the sound card application not running, everything is good ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#20 Tue, 31 Mar 2015 20:24:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#20 DisplayFusion Thanks, that's interesting!

As soon as I stop it, it starts up again, but if I disable the service and stop it, the disk activity drops to normal. DisplayFusion is still eating CPU, but the disk churn stops. ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#16 Tue, 31 Mar 2015 01:01:47 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#16 DisplayFusion Ok, that's really bizarre. I can't imagine what DisplayFusion would have to do with any of those services that are run in that instance of svchost. If you startup DisplayFusion again, can you stop each of those services (from the Services console) one by one and see which specific one makes the disk activity go back down to normal? ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#15 Mon, 30 Mar 2015 14:32:24 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#15 DisplayFusion Currently that service is churning 50 MB/sec on my HDD ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#14 Mon, 30 Mar 2015 14:05:05 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#14 DisplayFusion One more thing I discovered

  • In Sysinternals Process Explorer, open the Properties of the DisplayFusion.exe process
  • On the Threads tab, take a screenshot so we can see which threads are running up the CPU
  • Click the Thread that has the most CPU usage, and click the Stack button
  • Click the Copy All button and save that to a text file
  • Attach the screenshot and text file here

I'm running 7.1 Pro on Windows 7 Enterprise (64 bit dual core 2.8GHz with 228G - 4G free). My system is dual monitor, both wide screen. I have a personal background image that spans both screens and other custom settings.

I notice that usually after running either a Virtual Machine session or in some cases using conferencing software (MS Lync), that my system slows way down and becomes unusable. Sometimes if I go to lunch it may recover by the time I come back, but usually I do a hard power-cycle to reboot because the response doesn't even allow me to restart gracefully.

I've noticed when I run some diagnostic tools (Process Explorer, etc.) that DisplayFusion is up there in CPU and memory utilization (even when nothing is happening on the system). I've seen CPU running generally around 10-25% with spikes and memory consumption in the 100+M.

I don't know if this is the cause or just being adversely affected by another program - I haven't tried exiting DF when these situations occur - that will be my next test.

It's not crashing like it was previously, but its now eating up 100% of a CPU core.

I'm going to install Beta 2 that you linked and see what happens. ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#7 Fri, 30 Jan 2015 21:43:38 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#7 DisplayFusion Also, I'd recommend re-downloading and installing the 7.2 Beta 2 that we posted yesterday (http://www.displayfusion.com/Download/Beta/), as we made some more critical changes after we posted that test build in the forums. ]]> RE: Performance Issue https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#6 Fri, 30 Jan 2015 21:42:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/performance-issue/?ID=0b9f09b3-b8aa-4c8f-b32f-93a55579938b#6 DisplayFusion Ok, that's really strange!
