The latest update to version 0.8.1 for the T-Rex Nvidia GPU miner brings pretty good boost in the hashrate for the X22i mining algorithm used by the SUQA project with 10-20% higher performance compared to the previous release. This helps T-Rex 0.8.1 to overtake the top performance position for X22i from the CryptoDredge 0.11.0 miner that was the fastest previously in that particular algorithm. Have in mind that the skunk performance may be slower by 1% compared to the previous T-rex 0.8.0 version, but that should be fixed soon and meanwhile for skunkhash you can still use the older version for best performance. Do note that the T-Rex is a closed source miner with 1% development fee built-in. Also make sure you have a recent video driver installed (the latest for CUDA 10 support) as the binaries for both Linux and Windows are compiled for CUDA 9.1/9.2/10.0.
