[x] that I haven't found an existing compatibility report for this game.
[x] that I have checked whether there are updates for my system available.
Symptoms
Out of the box it doesn't work at all due to the Javelin anti-cheat which doesn't support Linux yet.
The game can be started in offline mode if proton-cachyos (I've tested upstream Proton and -GE and neither seemed to work) is used together with a third-party exe which lets the anti-cheat be bypassed. VKD3D-proton's state cache also needs to be disabled otherwise the game either doesn't start or just goes to a black screen and it hangs there.
After all this - the game does work almost perfectly (in offline mode obviously), except for the fact that sometimes it freezes for a brief period, and for a few seconds after that, the FPS is a bit lower than usual - unsure if this is related to the state cache being disabled or something else.
The launch options which make it work (taken from protondb) are:
echo "%command%" & VKD3D_SHADER_CACHE_PATH=0 "${STEAM_COMPAT_TOOL_PATHS%:*}"/proton run "$PWD/bypass.exe" & sleep 3; VKD3D_SHADER_CACHE_PATH=0 "${STEAM_COMPAT_TOOL_PATHS%:*}"/proton run "$PWD/F1_25.exe"; pkill "F1_25.exe"
