Running 9.7.1 Beta 10. CPU usage is crazy (i7-8705G). 4x 24" Dell U2415 monitors with one in profile. DF set to manage wallpaper, but only 1 monitor is dynamic, and the rest are pictures from local system.

Known issue that will go away with next general release?

GPU is Radeon RX Vega M GL with 4GB VRam (HBM2 700MHz).

Hey.
I have the same issue.

Win 10, geforce 1060, AMD Ryzen 9 3950X, 64GB RAM.
My CPU load is 15-20%.

It's OK after disable taskbar on all monitors (I work on 4) it's a bit better. No lags while switching windows / apps. With taskbar ON there is a noticeable, annoying lag while switching windows.

Downgraded to DF 9.7.1 Beta 6 nothing changed.

I use beta because of the issue with Edge Browser (this beta fixes that).
For some time it was working just fine ... and for a couple of days now it's bad.

Don't know why. I have upgraded to Beta 10 and probably had some windows updates. No more changes.

I didn't reboot after downgrading to Beta 6 from Beta 10.
Is this necessary?

I attache my debug diary.
Hope it will help. My windows default language is Polish.

Thanks in advance.
Regards,
Damian

Same issue here! I've updated to latest beta version and I'm still seeing 40% cpu usage by display fusion. I'm running latest version of windows 10 pro on an Alienware with I7 processor and 32gb of ram. I have to shut down DF to keep my cpu from maxing out while other processes are running!

Time for me to chime in on this one too. DF running 30-70% CPU.
DF Pro 9.7.1
Windows 10 20H2 (19042.685)

As I see last stable version doesn't solve our issue ...

This latest stable version seems to have resolved my issue. DF is only using about 2% of my CPU even with multiple task bars enabled.

Occurs immediately.

Unfortunately with the 50 MB limit, can't upload the dump file.

Mine has been OK since rebooting approx 1 day, 15 hours ago, and updated to 9.7.1 release yesterday as well. Current CPU between 2 and 3%. I'll report if it spikes again.

Win10 1909

I tried latest 9.7.1 ... no difference
CPU usage 15-25% right on DF start.
DF off CPU usage 3-5%.

CPU is back to fluctating between 12-36% (mostly right around 20, but it's bouncing up and down).

Really not good.

Seeing the same type of issues. Debug info from L2 log attached. Give me an FTP and I can send you a dump as well I had windows create.

Hi,

Same problem here. Usage >40%, starts immediately. Using DF Pro on Steam 9.7.1, Windows 10 Pro 1909 (10.0.18363).
DF used to manage the real estate on one ultrawide (5120,1440) monitor. I do NOT use DF for wallpaper management, or multiple monitors.
Logs available upon request.

Kevin - please advise on the best/easiest solution to this issue (i.e. what version is best to downgrade to, and where to get the install file). I've now also got my windows hiding behind the multi-monitor task bar (i.e. the windows maximize to the monitor, not the task bar). Leaving us all to run on 9.7.1 with this issue is unfair. I expect to be having clients with issues in the new year as they complain about performance too.

After a few days on 9.7.1 my DF cpu usage remains at around 2% with multiple task bars fully enabled. Just to be clear, that is not total CPU usage, just what is being consumed by DF. I'm hosting a camera security system on this machine that uses around 40% of my CPU so when my total usage skyrocketed to 80-100% I discovered that the culprit was DF. Looks like I'm the lucky one so far with this version solving my problem.

Uploaded

I upload two dump files. One from yesterday and one from today. I already tried to uninstall and reinstall. I tried older 9.7 and 9.6.1c as well and nothing worked. I restored setting before the dump today from when the system did not have the issue.

Cheers.

9.7.1 dump file uploading. CPU averaging around 20%. Definitely jumps when moving windows between monitors.

Upload failed (site 'down for maintenance').

I uploaded 9.7.1 DUMP no upload fail.

Hello,

I found the problem, in my case it was "Acronis Protection" after disable the protection, DF is now using 1-3%.

I keep you updated.

Kind regards.

Re: switching off Acronis Protection. Doesn't work for me. I followed this process:
reboot PC with DF and Acronis Protection (AP) running - High DF cpu
turn off AP - no change to high DF cpu
reboot, leaving DF on, AP off - still high DF cpu.

Latest version of DF, Acronis True Image 2021, up to date.

Still 30-40%. Creating dump file now. Uploaded successfully.

Yes, Running Acronis TrueImage 2021
Also TrendMicro Maximum Security 2021

Hi, downloaded and installed the test release. Better, but not there yet. Went from consistently north of 40% usage to around 15-22% (both immediately upon installation, and following a reboot).
This is an instant feedback, I'll leave running over night to see if % changes.
I did NOT uninstall the old version. The decrease in % would indicate that I am definitely running the test version. However, is there a way to check (about screen just says 9.7.1).
I am still running True Image 2021 with protection switched on.

I did send in a ticket to Acronis TI Support but they appear to be MIA as far as responding goes.

I also have had this problem for several days. CPU usage 20 - 40% constantly.

Windows 10 Pro 64 20H2 19042.685
Windows Feature Experience Pack 120.2212.551.0

Computer is unusable for AutoCAD 2021 when DisplayFusion is running so have disabled DF for now.

Also running Acronis True Image 2021 build 35860.

Peter.

Hi, overnight the test build has crept up from 15-22% range to 20-32% range.

I also have Acronic True Image installed if this is a clue.
And to bo honest during my investigation I also had a clue that Acronis is possible interaction software in this issue.

Hope you will be able to fix it.

@cbeckmann try Acronis live chat ... I naver had a problem to contact them.

I too was running Acronis protection when I first became concerned by the high cpu usage on my system. It was one of the first things I turned off to reduce the load. Turning it off did not resolve my high CPU usage issue with DF. Once I installed the latest version of DF its CPU usage went back to around 2% consistently. This morning I reactivated Acronis protection, updated it, ran a san, and let it settle in. DF is still using about 2% of my CPU.

Test build installed. CPU was previously jumping to ~15% consistently, and now hovering between 5 and 10%. Expect this will creep back up over time (which seems to be the pattern).

Not running anything Acronis.

Bitdefender is on my system (MSP version with firewall component disabled). Excluded the C:\Program Files (x86)\DisplayFusion folder from scanning, and no difference.

Fixed my issue. Great job! Now Display Fusion is using essentially no CPU!

Hi Keith - no difference when disabling 'Advanced Threat Control'.

Definitely better with the latest version though. Now hovering between ~5 and 11%.

Upgraded to 9.7.2 Beta 2. Still hovering around 10% (4x Dell U2415 monitors, if that is important).

Any word around this with Acronis True Image and the ransomware scanner there?

Uploading dump file. Zipped it first (134M instead of 46.

Hi, Any news on a fix for this? Whilst test2b improved the CPU usage, it still starts at 15% and creeps up to 30% over time. So, currently, DF is unusable for me. Thanks.

It looks OK on my side.
I've turned off that Acronis protection feature.

I agree that I was able to disable Acronis protection but I feel both Acronis and Display Fusion need to work this out together and get it working. I have support tickets open with both and I expect them to find a resolution or I need to pick one product and ask the other to give a refund since I cannot use it. To be blunt end users should get the function they paid for. Just disable virus and ransomware is not the answer hear nor is just disabling features of Display Fusion so both need to work together.

Yes I agree @cbeckmann but I also have Bitdefender and Malwarebytes installed so in my case it's ok to disable this feature in Acronis.

9.7.2 beta 3 appears to have resolved the issues for me (running Bitdefender).

Currently CPU is peaking at 3% (which is what I would expect).

Thanks Kevin.

Yes, Beta 3 seems to be considerably better.

I can't remember when the issue really became evident, but I can't remember it being specific to an acronis update... it was late last year that display fusion became completely unusable resulting in disabling and eventually uninstalling.

Hi, thanks for the reply. I've disabled Acronis Protection and the high CPU usage does indeed go away. I'm fortunate in that I also have Malwarebytes and BitDefender so (I think) can cover what Acronis Protection did. I cannot comment on when this happened, as, although I'm a long term Acronis user, I've only just become a DF user (having just bought an ultrawide monitor ). On a positive note - DF is, IMHO, excellent and essential for ultrawide monitors. cheers, Adrian

Uploaded new dump file now (1GB zipped to 250M). 9.7.2 b6. System was rebuilt with new WD Black NVMe M.2's about 3 weeks ago, and noticed the CPU hogging this morning. Exit and restart of DF did not make any difference.
