Whenever I try to start the game without VKD3D_SHADER_CACHE_PATH=0 with a populated cache, it crashes as soon as the intro starts loading.

The game uses the Javelin anti-cheat, so it needs a bypass for it to start at all.

The way to make it run is to place it in the game's directory, and running it before the game starts. Full launch options to make it run are the following:

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"

Log files

For some reason generating a log with PROTON_LOG=1 makes it go past the intro.

The attached log is from a bad "run" with VKD3D_CONFIG=vk_debug VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation VKD3D_DEBUG=err,info,fixme,warn,trace

does VKD3D_SHADER_CACHE_PATH=/tmp work?

Same thing happens.

Well, don't think we can help with games that require bypassing DRM/anti-cheat. Most likely game is just detecting any file system behavior like this.
