P: Add the possibility to disable full image preset preview

Perhaps replacing the preferences? The new option is working for me. 

And it doesn't work?! I disabled the option and hover is still active, so i thought a restart of LR would fix and nope!

Oh wait, i think i see now... they only disabled hover-previews for Presets and not Profiles? Are you kidding me?

Thanks Rikk.

And for those looking, the option is not in Preset or Interface... it's in Performance?

I would argue that it's a bug on some machines rather than an behavior change.  If the intent was to update the loupe image ONLY WHILE hovering over an image that's not what is happening for many people.  Personally I'm experiencing changes to the main image WITHOUT even hovering over the left panel.  The image will suddenly change to B&W or some bizarre flat image while using tools on the right side.  I have to either click on another image and back OR toggle into fullscreen "F" and back to revert back for an unexpected update to the main image to go away!  

I've been waiting desperately for a fix to the point of NOT bothering to process images until a solution is in place.  That's not fair when I'm paying monthly for a service that I can't reasonably use.  As for the reverting to a previous version?  That was not an option on my laptop that is still running Windows 7 and will NOT support windows 10 despite all of Microsoft's promises as well.  (Runs for about 1 month then always gets the blue screen every time I've installed Windows 10).  I Purchased new laptops on 3 separate occasions (all Windows 10) just to find they could not run Adobe LR without painful lags and finally resold or returned them.  Each machine I tried had an i5 or i7 processor and at least 16Gb RAM.  The performance was worse than on my current Toshiba Satellite P855 windows 7 i5 with 8Gb.  The performance to run LR just sucks on windows 10 vs 7.  And the three new laptops were $1,200 to $1,500 brand new Dell and Lenovo machines.  Why would performance be worse on several new Windows 10 machines than on an old Windows 7 machine anyway? 

Windows 7 meets the system requirements per the Adobe website (may 24th 2018 specs.) however Creative Cloud will not revert back a version unless Windows 10 is being used?  Why is that?

Adobe should be investing more time into efficiency to run on middle ware machines than bells and whistles that decrease performance and efficiency. 

I am really so tempted to scrap all future use of Adobe products and move onto something more reliable. 

Adobe LR should NOT take so many resources that a new laptop with a new processor and 16Gb of ram can not run efficiently. 

If cutting edge machines are what Adobe is interested in targeting, maybe they should create a LR Premium line and stop KILLING an crippling a huge portion of their customer base!

Rikk,
Why did you actually ask ? The result is the opposite of the expressed wishes. This choice doesn't make sense.

Laziness.

I am wondering, why you put it now in preferences and not as a simple toggle in the GUI, because most people prefered it to have it in GUI after your little survey here...

Rikk, I stopped looking at the releases when they wanted to overwrite 7.2. As mentioned in the Adobe forums I had some performance issues with the presets hovering even when the preview was switched off. Was this addressed at all post RC5?

Just in case - like me - it is not immediately obvious how to do this:-
FILE > PREFERENCES > PERFORMANCE  -  Untick box "Enable hover previews of presets in Loupe"
