I'm interested to know if anyone else has experience a decrease in photoshop performance in the most recent versions.
I used to be able to open dozens of 146MB TIF files and work on each without any performance issues. Now I can't open more than 25 without experiencing the following;
- laggy performance in tools i regularly use (spot healing brush, magnetic lasso, clone stamp)
- tools like spot healing brush don't show results until some other action is taken (eg zoom out)
- glitchy artefacts left on the screen around the image but within the boundaries of the toolbars (see image attached)
- clunky stepped zoom in and out (used to be smooth animated)
I haven't changed any settings within Photoshop but nevertheless tried all the performance improvements recommended in other forums/posts with no improvement. The problems specifically arise when more than 25 images are opened. Open 26 and the problems are there. Close one image leaving 25 open and they go away.
My system details are;
Processor: Intel Core i9 11900K 8-Core
Memory: 64GB Corsair Vengeance LPX
Windows Drive: Samsung 970 EVO Plus NVMe SSD 500GB
That looks like it might be a driver issue. (I noticed that NIVIDIA's last driver release was back in mid-February.) If you turn GPU acceleration off (via Preferences > Performance > Graphics Processor Settings), does that help? (Also try Preferences > Technology Previews > Deactivate Native Canvas.)
