Hello everyone

I've problems with Europa Universalis IV, it runs poorly on native. Frames dropping from 100 FPS to 20 - 15 FPS from slowest to highest speed and even paused.
On Proton the game runs flawlessly until I quit pause, it goes down to 25 FPS and doesn't goes up (unless I pause).

I don't know if I'm the only one with this problem, I searched on multiple forums for this problem but found nothing.
If anyone knows/have this problem would be nice to know.

My system specs:

OS: Manjaro Linux x86_64
Kernel: 5.7.0-3-MANJARO
