The caveat with try_files is it means nginx has filesystem access to
check the existence of the file and an additional stat call (or more)
- it can be in the open file cache, modern systems it's not a huge
deal, etc, etc.

But it won't help if you're fastcgi_pass to a remote server that nginx
does not have the same path to the file (or have access to the php
file) at all.
