If you mine RVN from Nvidia cards, i suggest you try ares miner - https://github.com/MultiMinerAres/AresminerRebuild/releases/tag/1.1.0

Today try him and for my small rig 5x3080Ti got the results - 283 Mh/s.
But i dont test miner for amd video cards.

If you can try mine from amd - write here pls.
