My computer was originally installed with other desktop environments, in fact, they work very smoothly, which means my computer has no problems But when I impulsively switched to kde, the frames kept dropping Whenever I open or close the software, it freezes Or by dragging the software to move or zoom in and out of the window, I can clearly see through the frame rate viewer that the lowest drop can be over 20 I really like KDE, but lagging is a bit bothering me. May I ask what the problem is?

Same here. It may be something with the nvidia

This could be a whole range of issues. Having the version of KDE Plasma you’re on and distribution you run might help narrow it down. It also could be specific to computer hardware, so specifying stuff like the computer and graphics card can help too, plus what driver version it’s on.
I won’t go into too much detail, but on one of my computers with an MSI motherboard had stuttering issues when using an NVMe SSD through the DMI link. (Esentially what I/O goes through outside of PCIe on Intel systems, AMD’s equivalent is the UMI.) Once I switched the drive to an M.2 slot that was directly connected via PCIe lanes to the CPU the problems went away. Never dug too deep.
From what I understand (and I’ll be corrected if wrong) this is due to cache being read/written to disk by the window manager. So anything that causes interruptions with the disk can affect it.
This can also be fixed by creating a tmpfs mount point to link ~/.cache effectively making your computer read/write from RAM for cache. That was my temporary fix until I changed the location of my drive. Would not recommend this if your system has less than 16GB of RAM.
This is similar to bug 487043, but in my case was due to hardware interactions causing the slow IO, and was happening after 6.1.

hi, welcome.
i see a lot of posts like these where KDE is under performing and the user has tried to add the plasma desktop to a non-KDE distro like it were any other application, expecting it to work out of the box.
this can work, but the effort required on the user end is often overwhelming due to how complex and deeply integrated the plasma desktop is with the rest of your system.
there are entire teams of ppl who’s sole job it is to ensure this integration goes smoothly and all the moving parts are working in harmony… even then, they get it wrong sometimes.
my suggestion is that if you really like the KDE plasma desktop, that you switch to a distro with a dedicated team of ppl behind it making sure it works for you.
kubuntu, fedora KDE, opensuse, tuxedo are all good choices.
otherwise i’m sure there will be plenty of suggestions here about what to try and fix yourself, if you are motivated.
for my input, i would look at what swapon has to say since that’s often a choke point.
