P: Add the possibility to disable full image preset preview

[FeedbackCommunityMember]

In the latest update, full image preview has been added when hovering presets.
While this is fantastic and really useful most of the time, when handling large files like stitched panoramas, my computer crawls to a stop as my 7700K is maxed out for each preset.
Could it be possible to disable that in the settings for such case ?
Thanks

>> Please make some checkbox in settings to turn it off.

Not in settings, Stanislav. The ON/OFF button must be directly accessible during the browsing operations. For example, as you described, one may want to do a quick browsing through a lot of preset folders (groups ?) with full live preview disabled and then activate it when selecting a preset in a specific group.

I think the best place for this button is in the toolbar under the viewing area, along with the other tools.

NB : There's another related problem with preset previewing that I commented elsewhere. I just noticed something that I consider as a bug : when hovering the presets, I observed that some of them had absolutely no effect. Very strange. Until I understood that if the settings modified by the preset are located in a development panel that is disabled (switch button set to Off), the live preview doesn't take these settings into account.

This is questionable. The live preview should show the full effect of the preset by temporarily re-enabling the setting panels that are switched off. Otherwise, this doesn't make much sense.

In other words, new feature not tested by someone using LR for real work.

"if the settings modified by the preset are located in a development panel that is disabled (switch button set to Off), the live preview doesn't take these settings into account."

Have you posted this as a separate bug report?  Adobe almost certainly won't see or act on it unless it's a separate bug report.

[Samoreen]

Rikk Flohr, official rep, apparently reported this issue to the development team.

[Rikk Flohr: Photography]

It hasn't been posted as a bug, John - rather I have asked the team to provide feedback on expected behavior to determine if this falls into the realm of bug or behavior change. 

[johnrellis]

It's hard for users to provide their opinions about the expected behavior without a separate topic.  It is certainly "unusual" that the preview resulting from hovering would be significantly different from the result of actually applying the preset.

[Samoreen]

OK. I will open a new thread.

[fhhfhthfght]

I also saw a big general slowdown after this update, not so one thing is due. But now it is really unmanageable even just to apply a preset.

In this thread, someone posted a fix in post #27:

https://forums.adobe.com/thread/2473568?start=27&tstart=27

I tried it on my Late 2016 loaded 15" MacBook Pro Touch Bar and it did stop the preset preview on the main window.  However scrolling through presets is almost just as bad, very sluggish and jerky as the small upper left window renders the preset preview.

This never occurred on 7.2, but I think the older version allowed you to scroll fast and it would not render until you slowed down.  The fix above seemed to force it to render every preset no matter how fast you scrolled through the list.

So the problem is more than just rendering the preview in the main window.

I've again reverted back to 7.2

The new feature where Lightroom previews presets on your photo when you hover over them is driving me crazy! Its extremely annoying and slows down the app and my editing workflow when this happens as I'm trying to scroll to the preset I want. Please add an option to disable this for people who don't want it!

I wrote on another thread also, but the full screen preview has practically made me hate editing. It's one thing that my laptop fans are screaming and CPU overloading, but also super difficult to compare with/without preset. I need to see the change to understand what a preset does, now I need to move cursor out of the list to see pic without preset. Hovering from preset to preset is not the same as you never see the original in between.

Damn I hate this live preview stuff. Same thing with Illustrator reacting to every typed number in type size for example. Changing type size from 10 to 11 you never see the actual change from 10 to 11, only sizes 10->1->11.

Honestly, my opinion of Adobe is so low at the moment that if I was within arms reach of one of the "support" staff I'd have to be restrained from dishing out a bit of my flat palm to the side of their cheek! 

The solution to the preview problem has been posted on the Adobe forums and it works, but now I simply cannot upgrade any of my apps because apparently my internet connection can no longer communicate with their servers to download the updates. Updates get to 3% and then just die. They (Adobe support) literally told me to change my ISP in order to update Lightroom. Can you believe that?

Here's the fix for this problem that was posted on the Adobe forums by F. McLion: 

1. Launch Lightroom Classic CC

2. Choose Edit > Preferences.

3. In the Preferences dialog, go the Presets tab.

4. In the Presets tab, click the Show Lightroom Presets Folder button. The root preset folder opens in the File Explorer.

5. In the File Explorer, navigate into the Lightroom folder.

6. Go to the link https://adobe.ly/2He219B and download the config.lua file. Copy the downloaded config.lua file into the Lightroom folder mentioned in the previous step. 

7. Relaunch Lightroom Classic CC.

The System Info dialog (Help > System Info) should display the config.lua flags entry as shown below, indicating that Lightroom Classic CC is now disabling the live preset preview in the loupe view:

Config.lua-Flags:
Develop.disableLoupePresetPreview = true

I can confirm that this worked for me. I have now also solved my connectivity issue (something 4 of the Adobe support staff over 4 remote sessions lasting an hour each time weren't able to do). The fix? Reboot my router...

With minor differences in OS this works well for Mac!  Thanks, Dallas, you have saved me from DPFF (development preset frustration forever)!

[CFBSr]

Here is the slight modification made for Mac

1. Launch Lightroom Classic CC
2, Chose (top menu) Lightroom>Preferences
3. In Preferences go to Presets tab
4. In Presets click on Show Lightroom Presets Folder button. Open as a new windows
5. In that window click on the Lightroom folder (not the Lightroom CC folder).
6. Go to the link https://adobe.ly/2He219B and download the config.lua file. 
7. Go to the download folder and drag the config.lua file into Lightroom folder in step above.
8. Relaunch Lightroom Classic CC.

The System Info dialog (Help > System Info) should display the config.lua flags entry as shown below, indicating that Lightroom Classic CC is now disabling the live preset preview in the loupe view:

Config.lua-Flags:
Develop.disableLoupePresetPreview = true

Can't do 7.2 because it doesn't recognize RAW from the Sony A7-III

[jacklthorpe]

This feature SUCKS... PLEASE turn it off or give us the option, ASAP.  My workflow along with others has come to a screeching halt.  

[Rikk Flohr: Photography]

Greetings all, 

I see a couple of users have posted a workaround involving the use of a 'config.lua' file to temporarily disable the current preset preview behavior. 

Please do not consider this a permanent fix for this issue. This was a temporary rough workaround for test purposes only. Use of a config.lua file to modify behavior can have unintended results and may cause issues with future installations. 

For those of you who've contacted me via email regarding special access to a preliminary update for a permanent resolution of the issue, we expect to have that available for you to review shortly. 

Thank you for your patience. 

[rpengale]

Thanks for being here, Rikk, and I hope you don't mind if I laugh a little at the phrase "unintended consequences" because that is precisely why this config.lua file is so appreciated.

Even if my laptop could perform the render instantaneously, I don't want my main image switching its presentation without my intentionally choosing it. Looking forward to Adobe correcting the unintended consequence of a mouse movement.

[FeedbackCommunityMember]

Amen

[CFBSr]

Thanks for the warning Rikk, so far all is well on my Macs.

May we expect that the removal of the .lua will not cripple  the preliminary update when it becomes available?

[simonsaith]

No.

[Rikk Flohr: Photography]

Thank you to those of you who volunteered to preview a proposed update to the Preset Preview behavior. You should have received an invitation for access to this at the email address you provided to me in your direct message. 

We look forward to your feedback in the test area on the changes.  

[FeedbackCommunityMember]

Would be great to disable this feature, as for me it makes not much use. The preset preview in the full image takes as long as to apply the preset and it slows d own my workflow. So please give us the chance to disable it.

[Anja Pfeifer]

Concerning the Question "how would you like to implement this"

Preferable (and in my mind the only logic place) - since it is something which changes the general behaviour - in the preferences. There where I as a user can find all the other general behaviours to influence the general behaviour of LR and computer related tweaks as smart preview use, parallel preview rendering, preview sizes, etc.
(Up to now this is one of the things i really love using LR - one place, where i can set my preferences and no need to search like hell all over the place)

Since when do we need to vote for stuff that is common sense. With every version Adobe 'officially' releases to its paying customers the performance goes years back.  All we get is alpha and beta quality releases. 

I see full screen previews jumping on my screen when the mouse was hovering over them 1,2 seconds ago. The gpu is turned off.
I'm running my catalogues from 2GB/s pcie flash drives on a quad i7 / 32GB iMac with smart previews. I use a catalogue per project to spread risk and will backup them every 10 minutes because of catalogue corruption which i never had before 7.3.  It's like Adobe tries to make this worser with every update for sport or something.

I cancelled my subscription and exploring alternatives, because i refuse to pay 1 cent for stuff that shouldn't be a release version in the first place. 
Just hit cancel, you can use it anyway untill your renewal date. Just let the Adobe descision makers know how you feel. 

It's obvious that the development resources of Classic are not what professional users deserve.
You want me as a customer next year Adobe? Fix your products or make it free of charge so i can't complain.
