Question

Lightroom CC vs Classic CC 64bit etc now totally confused please HELP!

Hi folks,

Sorry for amateur question that follows. I use Lightroom in my workflow but I am a light user and am now totally lost with it all. Hoping someone who knows can help with a few questions which, I suspect, are simple once you know what you're talking about. As follows:

1. I was an "old" Lightroom user before all the CC complication came along. One of my main criticisms was how slow it was to show images as you click through, I have tried all the various fixes (1:1 previews etc etc), I have two Xeons, a CUDA card, 24Gb ECC RAM and an M.2 SSD as my scratch / buffer disk so I don't think I'm short of power.

- I wondered if it could be somehow I am using a 32-bit version (read that in a few places)

- Nowhere, anywhere, in my current version of Lightroom (Lightroom Classic CC 7.3.1) does it tell me whether or not I am using the x64 version

- The forums seem to say it would be indicated in the title bar (it isn't), maybe in the splash screen (it isn't), maybe in the Help->About (it isn't)

- They also say the 64-bit version would install automatically if I'm using a 64-bit machine and running 64-bit Windows (which I am)... but how to check??

The chance I'm running 32-bit is the only remaining reason I can think of for it to continue to appear so slow when hopping from image to image, it actually makes the side-by-side keep / discard process painful when, surely, that's where it should excel.

2. On my laptop I installed Lightroom and it looks totally different. This was unintentional. I assume I have accidentally installed Lightroom CC (the "all new app") rather than Lightroom Classic CC.

- Is there any reason to believe that CC will be faster than Classic CC?

- If I gain speed by moving my main workstation to CC (in place of Classic CC), do I lose anything in exchange for what I gain? Is Lightroom CC functionally inferior?

3. Lightroom Classic CC seems, honestly, no better and no different to the previous version of Lightroom (standalone, non-CC) I had before I "upgraded" - other than the few additional features that came with the later product, most of which I do not use.

- Speed: I know it's a question asked many times before but it seems like there are contradictory answers (e.g. I read one article saying I should build 1:1 previews on import, and another saying for a big import this takes ages and I should definitely NOT build 1:1 previews on import!).

- If it's my priority to have the ability to flick between imported images, and to have the screen update instantaneously as I flick between images (e.g. when I have a loupe / side-by-side view and I want to put a preferred image up and quickly compare to the other similar images without delay) - should I indeed render 1:1 previews on import and, aside from a large scratch disk and enabled GPU, is there anything else I can do to make it fast.

I just struggle to believe that my machine - which is a sledgehammer to crack a nut when it comes to image processing, if ever there was one - cannot use all that power effectively through Lightroom to make it a pleasurable, lag-free experience. I must be doing something wrong. Or using the wrong program. Please help if you can... otherwise I'm off to Capture One or something else!

Thanks.

Alastair

There is no such thing as a 32 bit Lightroom Classic CC. All versions of Lightroom Classic CC are 64 bit.

As far as your speed problems, you need to be very specific and detailed. What actions in Lightroom are slow? You mention Loupe view, what else? Also, have you actually built 1:1 previews, or not?

Also, please state your exact CPU, your exact GPU, the exact make and model of the camera you are using, and the exact size in pixels (not inches) of your monitor(s).

Thanks for posting sorry for my slow response, been travelling.

In response to your three responses:

OK thanks then I guess that clarifies that any issues I might have are not related to using the 32-bit variant.

I may have to go back and spend more time on Lightroom to remind myself (as an light user). However from previous experience what I recall struggling with the most is that when I want to flick between different images (and I do mean "flick" i.e. I want to hope instantly back and forth between similar images to determine - for example with a run of twenty exposures for basically one image to keep - which of the 20 are the 1-2 keepers, and which are the 18 discards. I always found Lightroom laggy loading the next image, so it was not a "flick" at all and with such small image differences if it doesn't load instantly you can't really see the differences because by the time the new image draws itself and the image 'clears' (I don't know the correct term but the images start out blurry and then clarify) you can't remember what the previous view was like. To try to solve this I tried all the online articles I could find which led to me trying different things with rendering previews, cache size / scratchpad, etc etc.

I mostly don't care if background tasks take a while (although even then, with all this power, does it really need to be SO slow??) but it's the quick opening / quick changing of the images as I try to pair down the hundreds of shutter-openings to get to the tens of keeper images that I always found painfully slow. By comparison, even just using the Windows image viewer is much faster i.e. instantaneous. Similarly (from memory) I think it's much faster in Photoshop (e.g. Bridge) but I am much less famililar with PS so I prefer LR if I can make it quick.

Also, please state your exact CPU, your exact GPU, the exact make and model of the camera you are using, and the exact size in pixels (not inches) of your monitor(s).

CPU: 2x Intel Xeon E5-2640 v3 8-Core 2.6GHz [16 Threads, 20MB Cache, 3.4GHz Turbo]

GPU: 8GB NVIDIA Quadro M4000 GDDR5 [1664 CUDA Cores]

RAM: 32GB Kingston DDR4 2133MHz ECC Registered for Server/Workstation (2x16GB)

Camera: Sony Alpha a9 (latest firmware), shooting primary image files as Sony Alpha Raw (ARW)

Monitor: Eizo ColorEdge CG318-4K, DCI 4K (4096 x 2160) native resolution, 149 ppi pixel density

I hope that gives you the info you need to take me on another step.

Thanks again

Alastair

Please indicate if this problem happens in the Develop Module, or the Library Module. You don't say if you rendered 1:1 previews.
