P: Photoshop 27.10 and Beta 27.11 open and save image files over 50% slower than the previous version on Windows 11

Issue

Photoshop 27.10 and Photoshop Beta 27.11 have a significant performance regression when opening and saving image files on Windows 11.

System

- Operating system: Windows 11 Pro, build 26200
- GPU: NVIDIA GeForce RTX 5060 Ti 16GB
- NVIDIA driver: 616.56
- Displays: two monitors, sometimes used in Extend mode

Steps to reproduce

1. Open the same image files in the previous Photoshop version.
2. Open the same files in Photoshop 27.10 or Photoshop Beta 27.11.
3. Compare opening one image, opening 10–20 images, Save, and Save As.
4. Repeat the workflow with one monitor and with two monitors in Extend mode.

Actual result

- Opening image files is more than 50% slower in Photoshop 27.10 and Beta 27.11.
- Opening 10–20 image files is also significantly slower.
- Save and Save As are significantly slower.
- Photoshop feels less responsive when using two monitors in Extend mode.
- Rolling back to the previous Photoshop version clearly improves the opening and saving performance.

Expected result

Photoshop 27.10 and Beta 27.11 should perform at least as well as the previous version on the same computer and with the same files.

This appears to be a performance regression introduced in the recent Photoshop updates. The issue affects both the regular release and the Beta version.

      I am curious if someone that is seeing this slow down could try two things to see if it makes any difference:

      • Does turning off the Multi Threaded PSD Reading from the Preference->Performance panel?  Help or no?
      • Try loading just JPG images? Still slow?

      Needs more than a second to open a tiff or jpg. Horrible when opening more files. Went back to 27.9 and it worked well. Mac ist m1 Max with lots of Ram and free space running Sequioa 15.8.

      Same Problem on Mac. Thougt it was a Finder Problem, but it seems to be Photoshop. 10 Tiffs (1,1GB) need 10 seconds to open on a M1 max Mac.

      I'm having exactly the same problems with the same version. 
      File: TIFF + JPG
      Downgrading to 27.9.1 solves the problem

      Rolled back a version and all is well again.

      Experiencing similar issue - opening multiple 330mb tiffs and noticeably slower; definitely not for a lack of pc spec. Was looking for a solution and found this.

        True, the speed is noticeably faster on the older version.

        Files opened almost instantly previously.  Now like I’m in Win95. Is it the awfully poor AI tools slowing everything down while it loads in?

        What is the file type and if PSD/PSB were they saved with image compression or with no compression?

        Hi Dave,

        Thanks for asking.

        The files I tested were mainly JPEG images, as well as PSD/PSB files. The PSD/PSB files were saved using Photoshop’s default compression settings; I did not intentionally disable compression.

        The slowdown affects:
        - Opening a single JPEG or PSD file
        - Opening 10–20 image files at once
        - Saving and Save As

        Using the same files and the same computer, the previous Photoshop version is more than 50% faster than Photoshop 27.10 and Beta 27.11.

        My system is Windows 11 with an NVIDIA RTX 5060 Ti 16GB and NVIDIA driver 616.56. I sometimes use two monitors in Extend mode.

        Please let me know if you need the exact file types, file sizes, or Photoshop System Info.

        Best regards,
