Return of Reckoning

I try to play this game on Linux. I use CachyOS. I installed it through Lutris, as recommended. And game "works", with GE-Proton-10-29. Launcher works. I can launch the game from it, and join the server. But after a very tiny bit of playing, game just freezes permanently. I always forces me to close it by force, through Lutris. Does anybody know, what I could do to fix this? Just in case, here's my laptop's specifications:

CPU: Intel(R) Core (TM) i5-8250U (8) @ 3.40 GHz
Integrated GPU: Intel UHD Graphics 620 @ 1.10 GHz
Discrete/Integrated GPU: NVIDIA GeForce MX150
RAM: 8 GB

I have a similar, older Xiaomi Mi Notebook Pro laptop, and everything works fine under Windows 11. However, even on minimum settings the performance is not enough (50-90 fps in half-empty zones). I play mostly solo, and if warbands start gathering in the zone, I get 20-40 fps and constant lag. However, critical freezes happen very rarely, after frequent zone changes during flights due to memory leaks. Frequent reboots help a weak PC, especially after changing the active zone.
