Hi

Struggling with poor performance in Lightroom CC. My laptop is a i7 (boosts to 3.4Ghz), 16Gb Ram and Nvidia dedicated graphics. I thought that would be plenty for lightroom, but it really bogs down rendering and during develop activities.

Any tips for speeding up lightroom?

Thanks

Andy

I also find Lightroom CC very slow. Have you made sure it is using the dedicated graphics card? For some reason it only uses this in the Develop module and I think it is not selected to use it by default.

I had to roll back the driver on my Nvidia 860m as it kept crashing with the latest driver installed.I also changed the virtual memory settings which helped a bit. It's still very slow at times though, especially if Photoshop is open at the same time. I tend to close Photoshop after editing an image if I want to continue using Lightroom. Switching off Adobe Application Manager (in task manager) after starting Lightroom also seems to speed things up a tad.

Try renaming your video cache folder so it gets recreated. There's a nasty memory leak in some versions
 
I checked and it's definitely selected for use in lightroom under preferences/performance. Maybe I'll try an older version of LR instead.
 
Would be interesting to know if the problem surfaces after LR has been open for a while, ie if you quit and restart is it a little snappier
 
Try renaming video cache folder here: C:\Users\YOURUSERNAME\AppData\Local\Adobe\Lightroom\Caches\Video

LR will recreate a new one. See if that helps and post back?

Is your computer a Lenovo by any chance? Mine is and I have read a lot of posts on various forums where people were complaining about Lenovo laptops being slow using Lightroom CC

Funny you say that. Yes it is! Runs Premiere Pro just fine though. I've just signed up to CC properly now so maybe the latest update will help.
 
Unfortunately Adobe made a hash job of their GPU acceleration and it simp,y doesn't work on some cards very well.
I have a top spec iMac with 4gb GPU and I have GPU acceleration turned off. It's much faster that way.

I'll give that a try as well thanks.
 
Which laptop i7 is it? Don't forgot that it's not a 'real' i7. Probably be roughly equivalent to a desktop i3 processor. Don't expect it to boost to 3.4ghz either. This will only happen under favourable temperature conditions which are rare in a laptop. Even then only one core will hit 3.4 ghz and the others won't.

A desktop i7 will rip through rendering.
 
It's the i7 4710HQ. It is a real i7, comparison charts show it similar performance to desktop i7's. It's blazing fast in everything else, even Premiere Pro editing 4K video. Just seems Lightroom has a problem.

Switch off graphics acceleration, 9 times out of 10 it is better without it.

LR isn't very resource intensive and is usable on my Core-M Macbook (although everyones expectations differ but I also use a top of the range iMac), I would expect yours to be pretty good. Does your laptop have a fast SSD?
 
Hi, it's got a Sandisk Ultra 2 SSD. Not blazing but pretty quick. I'll try turning all gpu acceleration off.

Check the event logs for CPU throttling, where the motherboards firmware slows the CPU to control heat dissipation. If it happens during lightroom sessions there may be settings in Lightroom's preferences you can change.

Real in name perhaps but at a power sipping 47w it just can't compete with a proper desktop equivalent. It will spend most it's life at its base frequency of 2.5ghz and is thermally throttled in a laptop. Expect the desktop equivalent to be at least twice as fast given they can be cooled properly, overclocked and fed a decent amount of power.

Yes yes yes. Fact remains it should breeze through Lightroom
 
Well I think I've sorted it. My laptop has the 4k monitor, so I've dropped the resolution to 1080p and it seems much better. Although photos looked nicer in 4k :(.

It's going to depend on many factors such as image size being handled and task but it will be good enough but it won't breeze through Lightroom.

Back to the OP, I would be surprised if it was the 4K element, given the laptop has a 4k screen, it shouldn't have to use a quarter of its potential, even the Intel integrated gpu should handle a display resolution at 4K for such applications as Lightroom.

Yes, but rendering a raw image into 4k resolution takes CPU power.

I'm still surprised it struggles though.
 
Well I've gone back to 4K resolution. However things are much better importing with 1:1 renders. Takes a while with lots of photos but speeds up choosing and editing no end.
