Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

The game uses texture data format BC6 with num format Float:

[Debug] liverpool_to_vk.cpp:operator():701: Assertion Failed!
Unknown data_format=40 and num_format=7

Looks like Vulcan doesn't support such textures, is it possible to decompress such texture by hands to one of supported texture type, may be raw format? or same bc6 but Snorm, by normalizing floats (in case if raw will waste too many memory)?
beside it this sony-exclusive game runs smoothly

Reproduction Steps

Just run game and wait

Expected Behavior

No response

Specify OS Version

Windows 11
