Currently facing an odd behavior within RAGE 2 with Proton 4.11-6.
Game starts and works flawlessly, but usually freezes while loading from last save or checkpoint. The only thing that becomes available is the infamous Alt+SysRq REISUB.
I have tried a bunch of tweaks as proposed on multiple places also driver updates without luck. Also, I haven't found much relevant information in the logs.

I am also attaching steamapp logs.

Let me know what other info I can provide. In the meantime, I will keep looking if I can find something more relevant in the logs.

Thanks in advance!
