For most games, DXVK will try to load a configuration file into the directory where the logs are located, the directory where the game’s EXE is located most of the time. But this is not true for all games. If this doesn’t work with a dxvk.conf file in the directory where the EXE is located, try the following:
Place your dxvk.conf file in your user folder:
/home/xxx/dxvk.conf
Replace xxx with your username.
Add an environment variable:
DXVK_CONFIG_FILE=/home/xxx/dxvk.conf
On Debian, edit the etc/environment file and add the line above.
Note that this will automatically load the configuration file for all games under DXVK .
Restart the system.
These explanations are partly taken from the DXVK project:

This is by no means a stable method to fix an Nvidia driver problem and will never replace an update by Nvidia in order to fix it permanently. Nevertheless, I tested this method on about ten games, and it always worked. It is possible that it does not work on some games, not having had the centuries necessary to test them all, but if you are in this case, I hope you will keep your heart for a future optimized driver.
