Installed o3de from the deb file and it runs well. But I am having a very slow Emotionfx animation editor.
Getting only 0-1 FPS on the Render window and similar on the graph editor.

Device: PC
OS: Linux
Kernel: Linux 6.17.7-2-cachyos
Version: Arch
CPU: AMD Ryzen 7 7840HS
GPU: NVIDIA GeForce RTX 4060 Max-Q
Memory: 32GB
Nvidia Driver: 580.95.05

What can be the issue? Everything else works as expected.

Works for me on Bazzite with the same driver version. Are you on Wayland?

yeah, gnome 49.

#

Let me test on x11.

I run the engine with KDE/Wayland. Xorg might work, but QT's xcb backend works under wayland without issues too

#

When you start the engine, look through the logs to see if there are any errors/warnings. Not just in the console in the editor, but in a terminal window where you launch the editor

#

You can also try installing/running the engine inside a Distrobox to eliminate the chances that something in your base system is causing problems

Does this happen at very first run of the anim editor?

I've found that it'll start chugging if you have it open while using the editor play mode.

It happens immediately even without any animgraph file open.

Here is the Editor log

I don't have an answer currently, but I've recorded it on #1419889540105113753. There's also an older ghi that mimics your issue (mine) but for windows. Will record both of them on the thread.
