EN) When particle effects come into view in dungeons or flashy effects in battle scenes, the FPS drops very low. It becomes difficult to safely pass through various traps.
JP) ダンジョン内でパーティクルエフェクトが視界に入ったり、戦闘シーンでの派手なエフェクトが発生すると、FPSがとても低下する。各種トラップを安全に通過するのが難しくなる。

I updated my system, including the Nvidia driver (555 now), and things broke, invalidating my previous report. Proton 6.3-8 became a crashy mess, but I depended on that version to fix dungeon trap and battle system lag and needed a new solution.
- I switched to 9.0-2 and used
WINE_CPU_TOPOLOGY=1:0
. There can still be some lag/fps reductions, but I found the level acceptable. You can turn off Battle FX in game to help reduce lag further (I generally felt okay leaving them on, some issues). - The dxvk.conf file with
d3d11.disableMsaa = True
as its contents is still necessary to fix background texture scrambling. - Videos are still audio only.

DXVK_CONFIG_FILE="/path/to/dxvk.conf" %command%
After downgrading Proton, I had to go to controller settings (I use a Switch Pro) and switch from default to Enable Steam Input, then manually enabled Controller 1 in the game's settings.
The background in cutscenes and during dungeon crawling is scrambled, and the battle screen is similarly bad, rendering the game in a state where you essentially cannot see where you are going but can view cutscenes.
I fixed this by creating a dxvk.conf
file with d3d11.disableMsaa = True
as the contents, and adding DXVK_CONFIG_FILE="/path/to/dxvk.conf" %command%
to the launch options.
After this, there was severe lag in battle and near traps in dungeons. Switching to Proton 6.3-8 fixed this.
Videos do not work. You can mash past them. Converting the video to VP9/Opus allowed me to hear the audio, as well as running steam with steam steam://unlockh264/
, but this stopped working after switching proton versions.
Let's hope nothing changes between now and when I finish the game :) Game was a pain in the butt to get working.
