Photoshop 2021 slow and laggy [LOCKED]

I was having issues with PS as well so after updating all drivers and everything else, updated to the latest version of PS and then it all bombed.  I called a colleague who started laughing because he was having problems too- turning off GPU usage helps but.... he suspects it was a Windows update.

Intel Core i9-9900k, 32 GB of RAM, and Photoshop 2021 runs like garbage. Specifically- when I am using the brush or any other tool, it will freeze. I have to close my document and re-open in order to get it to work again. This will happen multiple times within minutes. I've had problems with Adobe before but now I'm seriously considering letting my subscription run out and replacing it with something else. 

I have the older version installed too and it helped but didnt fix all issues for me. Guess I just have to deal with this until the new update. Very frustrating. 

I'm having lagging issues here too, since 2020 version.
My lasso tool lags sometimes. To fix, I have to restart Photoshop AND Lightroom (I always work with both simultaneously).
Clone stamp is always lagging.
I didn't have that problem running PS2020 in my old Mac Pro 2012.  

Now I'm running PS 2021 in a custom built PC.  Ryzen 9 3900X, 64Gb DDR4 2666, X570 Asus mobo, Nvidia GTX 1080 Founder's Edition, Nvme for system and apps, SSD for cache and HDD for files.

I'm having the same problem.  The problem I'm having is with basic, simple operations, like opening a file.  I use a iMac Pro.  I open the program (with no other apps open) and hit command+O to open a file, and I get the damn spinning beachball for 3-5 minutes before the "open file" window even pops up.  This is after updating my OS and updating the Photoshop App.  Once the file is open, then the rest is pretty much smooth sailing, but getting started is completely sluggish.  It's irritating because I'm paying for this subscription and I don't feel like I'm getting my money's worth a simple operation like opening a file takes 5 minutes.

I think I might give up altogether. I've just bought Affinity Photo for £23.99. Im prettu sure it will do everything i need. I've already moved my video suite over to Davinci Resolve

I got Ryzen 3950x with 64 gigs of fastest ram available, 2x RTX 2070Supers and files run on m.2 or fast ssds. Everything is significally slower than in PS 2020, which was already slower than 2019. 2021 is unusable for pretty much anything - let alone 100+ layer composite work with huge pixel dimensions.

Adobe lets the basic functionality slip and and packs up totaly useless features like the new neural filters.

Also the memory handling is a joke, even if you allocate 64 gigs of RAM to PS, it barely uses half and preferres to write and read from scratch disk and you end up having some 30+gigs of free unused memory.

I have been running photoshop professionally everyday since CS5 and this CC-era has been total downfall of all things related to performance. IF there only was one viable option I would unsubsribe in a heartbeat.

We are currently PAYING money to be BETA testers.

I have been having issues also and wondered if it was my computer. Based on all of these posts it appears to be a PS 2021 issue. I thought I would test this theory. I still have PS 2020 on my computer so I started using it to see if it has the same issues and it does not. It is as speedy as ever. I guess I will be waiting on an update before I try using 2021 again.

Should we start blitzing Adobe on their social media with this thread link, maybe do a hashtag like #adobeScam

My desktop is Windows 10, Intel i7-9700K with 32 GB RAM and NVIDIA GeForce RTX 2070 super. After upgrading to Photoshop 2021, slow is the only way to describe performance. Photoshop 2020 worked fine for me, though I know others had problems. I've tried the performance enhancing suggestions (the driver updates, GPU, etc), reinstalled, reinstalled to a previous version, and nothing seems to work. I don't run any third-party plug-ins, so I know that isn't the problem. I can't use Photoshop on my laptop anymore because it's glacial. On my desktop, grids pop up when they should not, it takes a minute to change tools if I'm lucky, blending options take up to a minute to show preview, changing layers can take anywhere from a minute or two. When I try to move objects, nothing happens, then the object jumps into place, nowhere near where I intended. Slowly inching them to the correct position with arrow keys can take up to 30 seconds per keystroke. Shortcuts for things like undo and save do not work. Illustrator, so far, has worked just fine, but I'm dreading when it, too, tanks. I create outlines in Illustrator and move to Photoshop for color. I don't want to change to other software, but it's getting to the point I feel like I don't have another choice.
