Comment (by hydra3333):

 OK.

 It is a very significant difference in file size, and unexpected for me at
 least.

 I guess I'll have to experiment with '''-maxrate''' to find the right
 balance for my use cases.

 By the way, for interest - with nothing else changed, updating to the
 latest nvidia driver 446.14 and using nvenc encoding adds some mb to the
 encoded file.
