Lightrooom CC - a little too slow on my MacOS 10.10 system

i have just started using lightroom cc (been using lightroom and photoshop for a long time) and it's just sluggish. When I press R to get the crop tool out, the image flashes and adds on time to my editing. Also in the develop mode, when I go to the next image it takes a second for it to sharpen up on my screen. It's definitely slower than the last version of Lightroom. These are fine if I am working on a few photos but once I start editing 500-1000 images, its going to be annoying.

*macOS 10.10.3, iMac (27-inch, mid 2011), 3.4 Ghz i7, 16 GB ram, and AMD Radeon HD 6970M

Go to Preferences > Performance and disable the GPU and see if you're happier. Your GPU is probably struggling.

that helped a little bit, still slow for it to sharpen on my screen but there is no slow down with the crop tool. I know my video card isn't that great but I'm surprised that lightroom is going to be this taxing on my system. I'll see how it is for a wedding and see if I have to switch back LR 5. Thanks for your help Victoria!

With the GPU off, there *shouldn't* be any difference between LR5/LRCC.

Well there is ! On a french LR users forum, we're running a benchmark since LR 4. I've redone the benchmark this morning with LR 5.7.1 and LR CC. Based on bunch of dng files, we are testing, import, preview rendering and export.

Here are the results for my computer :
on import, LR CC is 30% slower !
on rendering 1:1 preview, LR CC is 18% slower !
on export from dng to jpef, LR CC is 40% faster.

I can give you the link, if reading french is not a problem for you. We're expecting more users to run the benchmarks these days.

Hope it can help !

To clarify, loading in Develop shouldn't be any slower in LR6 than LR5.

Most of the other things shouldn't be either, although a few bits were throttled in response to complaints about computers becoming unresponsive during certain tasks.

LR CC is completely unusable for me with that slow speed

Your results don't say whether they were done with the GPU on or off and you probably need both statistics from now on or at least choose the faster time between the two scenarios and specify whether it was the GPU on or off.

On my several-years-old Windows 7 computer, I noticed glitches and slowdowns with the GPU on so I turned it off even though it was supported in LR6.

On my newer one-year-old Windows 8 computer, the GPU remains on as things are smooth and faster.

Steve, why would the GPU matter for import, rendering previews and exporting?

It depends on if the GPU is used for rendering image in general, not just rendering to screen in the Develop module. It depends on whether the computations are faster in the GPU by enough that moving the data into the GPU memory and reading the result back out is less overhead than the time saved by the GPU doing the computations.

I wouldn't just assume that the GPU isn't involved without actually trying things both says and seeing if one way is faster or slower.

Fine Steve, I'll try without GPU.

on my brand new W7 core i7, 8GB ram, Lenovo Carbon X1 LR CC is slow near to unusable ...

I agree. Using LR CC on my spanking new fifth gen i7 with 16 gb ram and 1 TB SSD, it's painfully slow to use with/without GPU mode. I'm not sure if it's because my screen is 4k or not though.

Same here. On my imac, LR CC is much slower than LR5, with and without GPU acceleration on or off. it is slower in import/export, but especially slower in rendering previews....multiple seconds every image that makes it incredibly inefficient to sort thru images. (There is another thread just on preview generation slowness).

It would be great for Adobe to comment on this.

Amazing to me that after only a few weeks of release, there are almost 100 pages of LLCC problems on this forum.

and no reply from Adobe that goes beyond "Did you try turning it on and off again?"...

Do you know if there's any other ways to improve this? It is nuts how slow it is and I'm on a brand new MBP.

For me, loading speed of the images is the most important thing that Lightroom should do is load images quickly so that I can figure out which ones aren't sharp. Perhaps lightroom could have a louped area that sharpens immediately while the rest of the image loads? Any other suggestions?

Thanks,

Tex

Are you viewing in the Library module, and have you rendered previews in advance? And if so, where's your catalog stored (e.g. Internal vs external drive)?
