Just installed the new Lightroom CC and OMG the brush is HYPER slow...  like almost unusable with the GPU enabled. Like 20 times slower, no kidding. And my machine is pretty fast and the GPU pass and is compatible and pretty fast with anything else..  Slow like I do not see the results until I release the pen....  Same Machine, same photo LR 5.7 works perfectly fine.

If there is any doubt about that this is a LR CC problem and not my machine, here is a video of the very same thing with LR5.7.1 where you can see it is many times faster than LR CC.

Not only this is slower, even the simple zoom in to 1:1, the time the software needs to render the full resolution preview is a lot slower too. and I have a stripe of SSDs that gives me over 1000MB/s so it is not an HDD problem, plus is 5 times faster in LR 5.7.1 

At the office my HP Z820 have a Quadro 6000 and also is MUCH slower than LR 5.7.1   with and without GPU enabled.

On all the years I have being using LR I have never seen a new release to be this much slower than the previous one.

I have same problem, tbh the spot removal is even much worse with  LR 6

And btw, sadly the biggest problem is, that even when i switch off GPU, the 5.7 is faster then 6

I realy hope Adobe is fixing the speed issues on LR6 / LRCC because on my Mac everything seems to be slower.

Also the installation / upgrade from LR5.7 wasn't smooth. This is solved, but IMO, this software is not ready yet. It is slow with previews, brushing, comparing.

I am working on an 2013 maxed out iMac so I don't expect my Mac to be the limiter here. LR5.7 was way more smooth. Please fix this, Adobe.

I am having similar problems - working with 57,000 photos - some tasks in the library module are taking a over 30 seconds to complete.  It seems there is a problem with this LR6/LRCC - although I am not sure if it is a creative cloud problem.  I also noticed error messages about my software when not connected to the web - is this now essential for a creative cloud version to be connected to the web at all times?

Overall not a good update by Adobe.

Not sure about the connectivity errors since I have a laptop that's almost never connected to the web running LR6 and I don't see it complaining. Do you have something constantly connecting out in the background, other than the cloud?

I just upgraded to LR 6 and have the same issue.  I haven't explored all of the tools but the adjustment brush is glacially slow compared to LR 5.7.  I am running the following hardware.

Win7 PRO 64

Intel Core i7 5820K 3.3GH (6 core)

32 G DDR4 2133 MHz

GTX 970 Video (4G)

Crucial M550 SSD (512)

Western Digital Black HD (4T)

Dell U2412M Ultrasharp Monitor

This should be plenty of horsepower to run LR easily.  How could Adobe release this pig without adequate testing?

Please advise if there are any solutions short of reverting to LR 5

Best thing you can do is go bat to 5 until 6 is tested and ready if you are a heavy user of the adjustment brush, I am, and I could not use LR CC to do my job, it would take me easily 10 times what takes me on LR 5

I would love to go back, but the LR6 library isn't backwards compatible. Now I'd have to open a library file from March or something, with the whole gap of image work from March through July!

The speed issue is destroying my business - I depend on being able to upload 400 edited images to my website every 2 weeks or so

That is why I do not migrate catalogs until I sure the software is usable. And you should still have the old catalog since new ones are created and not replaced. You can also leave what you have so far in there and go back to the old good Lightroom for future jobs. Expecting to have Adobe to fix this I a timely manner is a bit of a fantasy.

You can also save the metadata of the files to the files itself and open the photos in the old LR by syncing the folders, the only thing it will ignore are new features if you used any.

The GPU acceleration is well known to slow down the brushes. Adobe warns us on that in their "notes on GPU acceleration" on this forum: GPU notes for Lightroom CC (2015)

In short, if you do not have a very high resolution (4K or bigger) and don't have an extremely modern GPU you really should turn it off as you won't see any benefit and might actually slow down certain actions. I really wish Adobe didn't turn this on by default as it is the leading cause of Lightroom 6/CC is slow concerns. If you turn it off, Lightroom 6/CC should be similar to LR 5.7 in speed. For some people this doesn't entirely solve it though but for me it is the same as 5.7.

I have several pretty recent GPUs at the office, in pretty recent HP workstations. It crawls to a stop almost with and without GPU when you have a decent amount of brushes. Just a few like to fix a few eyes and soften a skin not a Problem. But when you retouch jewelry like me, it's plain unusable.

This is the most frustrating thing I've ever experienced in my entire life. I haven't felt this massive of a problem since 1990, working on my 386...

I mean seriously.... This is asinine.

I have an EVGA GTX 1080 SC with dual 4k monitors and this input lag is MONSTROUS. I can't even begin to understand how this hasn't been fixed yet.

Why isn't this a priority!??!?

Curiously, Lightroom is one of the only Adobe apps that still doesn't have a "2017" version yet.

I wonder if a miracle update is still in the works? We wouldn't know because if Adobe monitors these forums, they certainly don't reply to anything to let us know we're being heard.

I made the "mistake" of synchronising the catalogue with Lightroom mobile.  Every time I used the brush it would eat CPU and then do a load of network traffic.  Once I stopped it syncing the CPU usage dropped dramatically.  I had to login to the web version and remove the pictures from there, telling the collection not to sync doesn't stop the individual photos from syncing.
