SHA-512 hash is 2.5 times slower on nvidia driver 545+

[baz]

I'm running hashcat on linux, GPU is RTX4070. I was using nvidia driver 535 for some time. After upgrading nvidia driver to 545 or 550, SHA-512 hash (-m 1700) and all hashes depending on SHA-512 became 2.5 times slower.
Running 

Code:

hashcat -b -m 1700

confirms it. I'm getting 2300 MH/s on 535 and 1000 MH/s on 545+.
Half of other hashes performance hasn't changed.
