Question

What determines performance of the AI remove tool?

I've been loving the new AI remove tool in 24.5, but I do find it quite slow often.

 

I've tested it with Windows Task Manager running, and when I get the spinning icon telling me it's working, I do see an increasing in CPU, RAM and GPU load, but not by a big amount. Nothing is anywhere near maxing out. As it leverages cloud technology, could my internet speed be a factor?

 

I'm running a Core i9 13900K, with 64GB DDR5 RAM and a GeForce GTX 1060 6GB. Yes I know my GPU is old, but when using the tool, my GPU utilization % is not very high (20-50%).

    I was fairly sure this tool doesn't need the internet, as it comes with what seems a hefty "AI download." I'll only know for sure when I update and "pull the plug"...  [I see Trevor already confirmed it.]

    Mark I have an almost identical system, but with an RTX4080, so can we compare somehow?  Click to expand the image below, and copy and paste into Photoshop.  I used a 50 pixel fully hard preset for the Remove tool. Touched down on the left and shift dragged to the other end of the black line.  You can get the time from the task bar, but I like to have it turned on in the Info panel (via its Panel Options).  You can see it took my system 6.0 seconds.

     

    I don't know if the Remove tool needs an Internet connection Generative Fill does.  I suspect not, but for FWIIW I am rural NZ and have VDSL2 with 72Mbs down and 12Mbs up.

     

    I have Image Processing options set to More Stable The above test was slightly faster with that option set to Faster

      I have tried a couple more times, and got 5.6 and 5.4 seconds.

      BTW I did ask a friend to compare Gen Fill performance because she has gigabit Internet speeds.

      This is one of those new AI-powered functions that rely heavily on the GPU.

       

      Adobe officially recommend an RTX 3060 or higher/newer:

      And, as pointed out, the key to a fast system is a balanced system. A GPU to go with that i9 would be RTX 3090 and upwards.

        Thanks for the link. I hadn't seen that recommendation before! I guess it's time for a GPU upgrade then.

        Hi,

        How slow is it on your computer. I'm on a 3-year old Surface Pro 7 Plus with integrated gpu and having no problems with it.

        It can take sometimes 5-10 seconds. Occasionally it is only 1-2 seconds, but usually slower.

        Hey, @Mark-Hazeldine. I did some light research, and the combination of GPU & CPU you have are leagues apart & some online bottleneck calculators suggest up to 80% graphics bottleneck.


        The GPU is too weak to keep up with what the CPU can achieve. If possible, borrow a recent GPU from a friend or colleague before upgrading to test the difference. I am at the opposite end with a CPU weaker than the GPU.

         

         

        Let me know if you notice an improvement. Thanks!

          I am aware it's unbalanced. I recently built a new PC, but decided to keep my old GPU for a bit to evaluate the performance and see how much I needed to spend on a GPU. A YouTube channel called Tech Notice said that photographers don't need a very powerful GPU for photo editing, as Photoshop is mainly CPU driven, but he said that before this new tool came out. I suspected that my GPU might be the bottleneck but the Windows 11 Task Manager seemed to say it isn't. Why do you think Task Manager would show a low utilisation and low memory usage if the GPU was holding things back?

          So, after a bit more testing, the speed has now increased back to what it was a few days ago, last time I used it. I then spoke to my Dad, who was in the house and watching something on his smart TV and asked me if I had experienced the internet being slow earlier. I actually had because I had a Twitch stream playing in the background and it was playing at a lower resolution automatically. So, it seems to me that internet speed can really affect the speed of the remove tool, but a LOT. When the internet is working fine, it'll remove an object in say half a second, but when the internet is going slow, it can be 5 or even 10 seconds.
