FPS drop from 60 to 30

Hello, Today I installed manjaro plasma desktop but when I have a maximazed window, fps drop from 60 to 30 fps. Or when I’m doing nothing fps drop. I can only get them up if I open the Konsole. What can I do?

Welcome to Manjaro! :smiling_face_with_three_hearts:

  1. Please read the information behind this link. It will help you to post necessary information.
  1. Please press the three dots below your post and then press the :pencil2:
  • If you give us information about your system, we can see what we’re talking about and make better suggestions.
  • You can do this by using inxi in a terminal or in console.
sudo inxi --admin --verbosity=7 --filter --no-host --width
  • Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
  • Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.
  1. Copy the output from inxi (including the command) and paste it into your post.
  • To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.

Have you already :mag: for your problem in the forum ? (Wisdom lies in asking → listening → reading :wink: )

Have you installed nvidia-settings ?

Yes, I still have the same problem.
I had the same problem on Arch Linux, but I couldn’t fix it

It is problem with 545 Nvidia driver. Add to your .bash_profile this:
export KWIN_X11_FORCE_SOFTWARE_VSYNC=1
