P: Is there an optimal setting for Select and Mask? I can never get it to work efficiently :-(

I get this exact issue. 128GB DDR4 3600 RAM, Ryzen 9 3900x, 1070 nividia 8gb, 1TB m2, 2 TB SSD, x9 3.5 drives. My system is state of the art but this is unusable! What the heck is going on?

Also, adobe can you please fix the issue in select and mask were the scroll wheel zoom just randomly stops working. This has been going on since Cs6! Cannot believe I pay for this software.

Above video is a fresh reboot, fresh load of PS with single image. After working on 5-10 images it's significantly slower still.

Brush lags 1-2 seconds behind cursor, after releasing the pen there's a 3-4 seconds delay before the screen updates with the latest, often incorrect, change. It's very frustrating to use, if it wasn't for Topaz I'd be doing a lot more swearing.

The only reason I revisited S&M at all was due to the latest patch promising improvement to the CAF and masking algorithm but the speed sadly writes it off again 😞

Den, can you give specifics of what is slower?

i was testing yesterday and found that the old Refine tool is still faster than S&M! For those wanting to use it, hold down Shift and then in menu>Select>Select and Mask.

intel 9900K, 64Gb RAM, 1070GTX Windows 10 Pro, SSD work drive, SSD scratch disk, SSD system drive. Clean install of Windows and PS out of despair. Latest NVidia creative drivers.

Performance of Select and Mask workspace is unusably slow.  I'm still using Topaz Remask 5  (Not  the AI version) because the photoshop tools are too slow to use.

Same here, it's frustrating as ever. Photoshop isn't even using all my resources so it's NOT a case of my system's abilities. 

Two years later and we're still dealing with the same issue here. Using Select and Mask with any sliders set to anything other than zero is barely usable with images larger than 10mpx.
Just tested again and nothing has changed.

My machine is massive: i7 9700, Nvidia 2070, NVMe scratch at 3GB/s.

Jerry,

I tried this on my iMac and on my Windows rig, which is way inferior to yours:

• Adobe Photoshop Version: 19.0 20171103.r.190 2017/11/03: 1143799  x64Number of Launches: 4
• Operating System: Windows 10 64-bit
• Version: 10 or greater 10.0.16299.15
• System architecture: Intel CPU Family:6, Model:10, Stepping:9 with MMX, SSE Integer, SSE FP, SSE2, SSE3, SSE4.1, SSE4.2, AVX, HyperThreading
• Physical processor count: 4
• Logical processor count: 8
• Processor speed: 2295 MHz
• Built-in memory: 16354 MB
• Free memory: 9425 MB
• Memory available to Photoshop: 14420 MB
• Memory used by Photoshop: 70 %

I didn't get any delay at all on the iMac and sometimes a 1 second spinning wheel on the Windows machine, but eminently useable.

What is different about both of these to my MacBook Pro, where I get the same problem as you, is that I have two scratch disks configured on the Windows machine and three on the iMac.

Looking at the spec above, I think you only have 1 configured, as I do on the MacBook.

By rights, your Windows system should be a lot faster than mine - you have twice the memory I do and your CPU is somewhat faster as well

The other difference on the first test I did with the Windows machine is that I was accessing it remotely via RDP at the from the MacBook, so OpenGL was disabled, because it causes graphics conflicts on RDP connections. I thought that might be making a difference. So I just tried again, using Jump to access the Windows machine, which doesn't disable the OpenGL. It did make a slight difference, but in the wrong direction for the theory about OpenGL, as there are no spinning wheels at all when I use  it via Jump and the OpenGL is active.

That really only seems to me to leave the scratch disks as the main difference, between my config and yours, so you could try configuring a second scratch disk and see if that helps at all. It may not, but it might be worth a try.

Hey Paddy, yea it came in 19.1 and I have tried it. I go through the same struggle when refining the edges though. Select Subject only gets you part the way. I have given it a try, too but there is something definitely wrong otherwise. I have used photoshop for some years and it's the first time I've experienced this kind of performance when selecting. I still haven't tried re-installing with fresh preferences so keen to see what this would bring, if anything.
