Regarding the release 7.52, it could be useful this post: https://github.com/rigaya/NVEnc/issues/580

As of version 7.49, 3 new encoding options have been implemented. The options give an excellent result in terms of encoding quality at HEVC/h265. The options are:

--tune
--tf-level
--lookahead-level

If you want the performance before 7.49, use them like this:

--tune lowlatency or ultralowlatency
--tf-level 0
--lookahead-level 0

Lower performance is primarily due to --tf-level and --tune uhq. As of version 7.50, the default value of --lookahead-level is 0 and you don't have to explicitly set it.
If you want maximum quality, then use:

--tune uhq --> only supported by Turing+ architecture.
--tf-level 4
--lookahead-level auto
