Na, it doesn't but 14.4 seems to be the best option. What really helped to steady the frame rate a little bit is the same fix I've already used for Rage.
You have to let the game create a temp folder for texture data. Create a folder e.g. C:/Wolfensteintemp and use the parameter
+fs_cachepath "C:\Wolfensteintemp"
You can check if it uses the folder by typing fs_cachepath into the console.
This only works as an exe parameter, putting it into the config file doesn't seem to work.

Thanks for the tweak idea, was able to finally play the game without crashing.
