Game suddenly running on low fps (Kingom Come Deliverance) with Heroic Game Launcher

Hi there.

I am using Heroic (flatpak version) to play Kingdom Come Deliverance. Laptop is a hybrid Intel i9 with RTX 4080 and the game run 100% fantastic until yesterday. Today I’ve only accessed openSUSE Slowroll (KDE) without even trying the updates and, weird, the game runs at 11 fps.

Do you have any idea to troubleshoot this?

So far I’ve tried:

  • rollback to yesterday’s snapshot
  • import the game again in Heroic
  • rebooted many times by using sudo prime-select boot nvidia (also tried the offload since it was simply working automaticly)
  • tried to enable “automatic detect dGPU” and “AMD FSR”
  • do the system updates
  • try to run the game in X11 and Wayland, both are running at approximately 11 fps (yesterday was at least 60fps on Wayland)
  • did a chkdsk /f of my NTFS partition with Windows

On Windows, the game is running OK, so I feel like wanting to exclude that dGPU is broken.

I am also sure that Nvidia is at least working since my external monitor and audio work. Please feel free to request more info if needed and I’ll provide.

Thanks in advance.

Since I installed Heroic with Flatpak, I found out that the config files of it were under my home, in .var.

I uninstalled the flatpak, cleaned the folder, even went to my home folder, under the wine prefix files, and cleaned it as well just to be sure.

Re-installed via flatpak again (Discover), imported the game again, worked like magic. And I am 300% sure that I didn’t touch anything. Welp, at least it is fixed.

Enable timeline snapshots using snapper for home dir, you can do a diff or rollback in the future to narrow down the issue. :leaves:

Nice, I was thinking the same. I should only think about it and see if it’s also worth it to Not doing it! Otherwise I’ll just look for the command and enable it.

It’s quite easy:

sudo snapper -c home create-config /home
# edit /etc/snapper/configs/home to enable timeline snaps
