OK if I start a new game, even on fresh prefix I also can reproduce the hang. If I start a new game and tick the skip intro box, it loads properly to the game without having the 'torture' intro.
The rest of the game seems to work well for me, the only part where I detected the hang was in that particular moment at the starting cinematics. What is your hardware and distro?
Prior to testing I deleted the prefix and set it to standard 7.0-6 proton with no startup options as I said. I've only added `PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1 %command%` in a later attempt exactly to offset the fsync-...
Does it crash if you (all of them): - delete the prefix (or rename it, to keep the old files just in case, the savegame for example) - use standard 7.0 Proton not experimental or beta - use standard kernel instead of TKG...
When the hang occurs, one process stays at 100% CPU the whole time in the call (caught by strace): `futex(0x7fc9d3e267a4, FUTEX_WAIT_PRIVATE, 12, NULL` Using `PROTON_NO_ESYNC=1 PROTON_NO_FSYNC=1` doesn't change anything
