Lightroom Classic 9: Extremely slow after update

After updating LrCC to version 9 - the program is now incredibly slow.  All graphics accelerators are on and working. 

Cropping is difficult and staggers now, the develop module is slow too - all sliders lag to the point where it's impossible to work on anything - especially when you have a high volume of images to deliver.

That sounds like a graphics card issue, or the graphics card is too old to be supported anymore. Which card, and have you updated the driver?

I tried resetting preferences - no change. I'm having the same issue as the poster below - you move the mouse and the crop only changes when you stop moving. 

I also went into the preferences to store presets with this catalog and that crashed the software out. Might be another bug.

In anycase, all my drivers are up to date now. Sliders work fine, but crop is unusable.

Hang on - I haven't updated Camera Raw yet, or Photoshop - would that make a difference?

Checked graphics support in Lr - and it appears its not seeing OpenGL?

Here's the dialog as i see it.. The text in that box is also flickering..

It's not using OpenGL on your system because LR is now DirectX instead. Your GPU is fine

Cool thanks. I've had to revert back to the previous version of Lr - it's working perfectly again.

I've posted a possible workaround in the forum thread that Victoria pointed to. Give that a try. Thanks.

In general, Lightroom 9.0 is slower.  My graphics card is a 1050 TI 4GB and LR indicates it is supported.

 My comments below are based on editing 45mb raw files from my Nikon Z7.

Basic Develop Sliders are slower and more "choppy".

Range masks are slower to paint and adjust.  Rather than following my mouse movements, some range mask adjustments turn into straight lines and then need to be erased and retraced.

Sharpening sliders also seem slower.

I have tried turning GPU Off, On, auto, custom in preferences and that does not help.

Very frustrating that the new release on my I7 6 core 32GB ram 1TB SSD (for catalog end executable code) system now provides a less functional and usable experience.

The workaround is intended for customers who experienced crop slowdown only.

I was brought to attention of this camera raw thread https://feedback.photoshop.com/photoshop_family/topics/camera-raw-lagging-issue-after-update-dng-pictures). One suggestion there is to stop the service "Acronis Active Protection" service on the machine (an anti-ransomware technology). One Lightroom customer reported to me that turning off the "Acronis Active Protection" have helped resolved the slowness he experienced in the latest Lightroom update in multiple ways, including the sliders and crop, even without the above workaround. Please give this a try if it applies to your particular situation.

I performed the uninstall and reinstall as suggested earlier in the this thread.  I also did the same for PS and Bridge.  PS was giving me some funky brush quirks (and still is).

LR still takes about 3-5 minutes to load.  It did this in version 8.x as well.  FWIW, the first launch of LR after the reinstall was quick.  After doing some round trip editing of LR -> PS -> Topaz -> PS -> save to LR, the next launch of LR was very slow.  I also notice some auto import issues with PS saving back to LR.  

I also noted the mention of the Config.LUA file.  I checked my settings for LR and noticed an entry for OpenGl and took a screen shot (inserted below in this response).  I thought that was strange since my understanding is Direct X is now the norm for LR 9.   There is a line in the System Info for my 1050 TI graphics card and does indicate Direct X.  I overwrote the entry with the one posted for the crop fix.

I also noticed in this thread about Acronis Active Protection causing a problem - yes, I use Acronis True Image and active protection is on.  I suppose, since I am running Norton, I can experiment with turning off Acronis Active Protection.  I'll report back on whether this helps or not.

Side comment - One would think that a public beta would help Adobe to find bugs before an  official release.  I contacted Adobe offering to be a Beta tester with an NDA but never heard back, one way or the other.

Well, the thing about this one, 'Acronis Active Protection' being the issue is, it's something not every beta tester would have. Even if one person had it installed and reported poor performance, it would be tedious to isolate that one part of a given program. Unless the tester went switching off one service at a time of course. Anyway,, delete that config file and switch off Active Protection and you can put an end to all the troubleshooting you're doing :-)

All my issues are resolved by turning Off 'Acronis Active Protection'. See if that makes a difference for you too.

Sorry if I misunderstood. It seems two problems have become intertwined in this thread:
  • P1: a general slowness in displaying changes made with sliders, and
  • P2: slow display of changes made with the Crop tool.

Along the way, we also had five recommended workarounds:
  • W1: Reset Preferences (e.g. using Rikk's steps above).
  • W2: Reset Preferences and config.lua flags (e.g. David Hewison's steps above)
  • W3: Update graphics drivers (e.g. David Hewison's post above)
  • W4: Enter an exception in Acronis Active Protection Settings (e.g. William Naiman's post above)
  • W5: Disable Acronis Active Protection (e.g. Simon Chen's Response above).

Perhaps someone can just clarify if I've summarised the problems and proposed workarounds completely & accurately, and –while we wait for the results of a formal problem analysis– clarify which of the above workarounds apply to which problem(s). Cheers!..

There are likely more than just 2...

P2 is affected by W2
P1 is affected by W5
W1, W3 are general fixes for all slowness and fixes some slowness complaints by those not encountering Crop-specific or who are not running Acronis.
