The latest CryptoDredge Nvidia GPU miner version 0.15.0 comes with fixes for Lyra2REv3 performance, but more importantly it also adds support for the new MTP algorithm currently being used by the Zcoin (XZC) project. It is recommended to immediately upgrade to the new 0.15.0 if you are mining Zcoin (XZC) at the moment with the djm34 ccminer fork as you should be getting more than double the performance with CryptoDredge on GTX 1×00 series and more than half on RTX 2×00 series, so again worth mining even with the recent hashrate increase we are seeing. Another important thing regarding MTP support is that you need to use Nvidia graphics card with at least 5 GB video memory, however there are no special requirements for CPU and RAM, so 4 GB System RAM must be sufficient (older miners had larger memory requirements!). Also note that compared to other algorithms MTP transfers a larger amount of data to the pool, so this may be a problem for limited and slow internet connection speeds.
Do note that the CryptoDredge miner supports only Nvidia GPUs and is a closed source software that comes with 1% built-in developer fee for all supported algorithms, however the dev fee is 2% currently only for MTP mining, there are binaries available for both Windows and Linux (CUDA 9.1/9.2/10.0).
