Huge Performance issues on LightRoom 6 on my Mac

Finally installed LR6 upgrade from LR5.7. Really slow and unstable. I have 8 GB 1067 MHz DDR3 running 10.10.3 on a 2.53 GHz Intel Core 2 Duo on a Mac mini (Late 2009). I've had no performance issues with LR5.7 but LR6, now 6.1, is not working properly. What is going on please?

I find it utterly amazing that an upgrade can be released and sold to people like me that appears to be full of bugs.

Try turning off GPU acceleration. The MacOS 10.10 video drivers are causing issues, and the LR team is still trying to get to the bottom of the problem.

How do I turn off GPU acceleration?? I have a iMac 3 GHz Intel Core i7, 16 GB and LRCC has been a disaster. Freezes, lags, especially when processing the new HDR images. I've lost count how many times I've had to force quit.

The checkbox is located in the Performance pane in the Lightroom Preferences.

Lightroom > Preferences > Performance

Don't expect to much!

It just didn't work for me. With or without GPU acceleration: no positiv effect on my system! LR stays very unstable. As long as there is no solution I'm doing most of my work with PS and DXO...

Thank you for your response. I've turned it off after response from LR tech people but it still does not sort out the terrible stability and speed problems - eg I try to scroll down my files to import and get stuck with the revolving wheel for ages then have to force quit - the speed issue is just terrible. Also everything I do has a delay on it - I use the sliders for highlights etc and there's a delay.

I just want my money back for Adobe to sort out this beta version before they re-release it. Amazing that the LR team is still getting to the bottom of these issues - surely that have beta tested this on Macs? I also read that Windows users are having performance issues.

Same problem! I'm running LR CC 2015 on an iMac 2,9 GHz Core i5, 8 GB. There has been a kind of small update a few days ago but no effect on the performance and the stability at all. Working with LR has gotten nearly impossible. Don't they perform any testing at Adobe before such a miserable product is broad to the people?

Same for me too.
Running 2.9Ghz Quad Core i5 with 8GB RAM on iMac.
I have a large number of images which need to be edited over the next couple of days, and this is screwing it up for me. I too would like to see a months subscription refund for releasing such poor updates on us - that is assuming Adobe resolve the problem within the month.
I thought the point of CC would be regular incremental and stable updates, not beta quality.

LR 6 CC is installed on 2014 Mac Pro 12 Core Dual AMD Fire Pro 700, 32 GB Ram 1TB SSD, Dual Apple HD 30 Displays

When I first open LR CC, all is ok, tools are fast , Radil Filter is fast, after a short time in Develop module, the program starts to slow

The Radial, and Clone tools become VERY unresponsive, as well as global adjustment tools also slow,

After 1hour when using the Develop Module, the radial filter become UNSTABLE, the filter was VERY unresponsvive,then it would cause the entire screen to go Black, no image displayed, then the radial filter disappeared, and was not on the image.

As far as I am concerned LR CC IS NOT useable, I am amazed at how this product has been released, I also run Perfect Photo Suite 8.5, and DXO Optics Pro 10, both are VERY fast and stable.

Anybody had any joy from Adobe in terms of feedback or information on any pending fix?

I have tried to get some sort of response from them but to no avail?

Does capture one work with OnOne software as a plug-in? If so I might give it a try.

Nothing. My last FB message has been ignored. I have gone back to LR5.7 but it too appears to be running slightly slower - probably because I upgraded the directory in LR6. At least so far it's still stable. What a joke.

Okay, so I finally got somewhere (albeit that was no help) with the Adobe support team.

It all comes down to Adobe enabling LR to utilise the GPU to improve performance. I was informed that the GPU in my 2 year old iMac does not meet LR specification any longer! They referred me to this link which is worth reading:

https://helpx.adobe.com/lightroom/kb/...

Obviously I cannot change the GPU, so Adobe are effectively saying buy a newer computer.

Understandably I was even more angry and frustrated than before once having this conversation. The solution of course is to revert to LR 5.x and continue to pay your subscription but without the benefit of upgrades (or buy a new computer).

Having taken a deep breath and refrained from expletives I trawled the web further for user experiences and I think I may have stumbled across a solution. 5k iMac users have been having some issues due to display rendering requirements, one user as part of their solution increased the LR cache size. I thought I would give that a try, after all if the option to enable the GPU had been disabled I felt that despite what Adobe support were telling me there should then no longer be an issue.

Bottom line: I increased the LR cache size from the default 1GB to 50GB and turned off the restriction on Video caching. I do not seem to be experiencing the same issues any more. Intuitively that makes sense to me. I have even re-enabled the GPU option on the basis that is another 500GB available for rendering. All seems okay for now.

Time will tell if this is a solution, but thought it worth sharing. Give it a try and let the forum know if it works for you.

I am working on a brand spanking new MacPro, (32Gb, 1 Tb flashdrive, 2x500Mb graphics cards) — and the clone tool is incredibly slow. The brush tool is not much faster., Turning off 'use Graphics Processor' actually helps a little, though not much. Right now I am regretting updating to LR6 - on version 5 I could work much faster. Hope Adobe addresses this issue quickly!

I am also having the same issue! Everything I do gives me the spinning wheel! I'm on 16GB RAM and 500 SSD
