Another open-source fork of ccMiner called supminer (source) is now available, an optimized version from the operator of the Suprnova mining pools that promises up to 10% better performance than the recently released nevermore ccminer fork. The supminer ccMiner fork comes with with no developer fee, but you can show your support by mining Ravencoin (RVN) on Suprnova’s RVNCoin Pool. There is an official 32-bit Windows binary release available compiled with CUDA 9.1, so make sure you have up to date video drivers on your mining rigs. The code is compatible with Linux as well, though you will need to compile it yourself (make sure you have CUDA 9.1 installed to compile from source).
In theory the supminer should be faster than the other available ccminer forks with X16r support, but you should test and compare the different releases and see what works and performs best on your hardware. Feel free to report hashrates and stability on your mining rigs and how supminer compares to the nevermore and enemy miners. When comparing hashrates make sure you compare on the same algorithm, because hashrate varies depending on the currently switched to algorithm. Do note that the performance optimizations should not work only on the X16r algorithm, but should also help improve performance on other chained algorithms supported by ccminer.

VDN (vDinar) is a relatively new regional-oriented crypto currency that has been getting more attention lately. It was CPU-mineable up until recently, though it seems that there is a ccMiner fork available (source) supporting the vCrypt algorithm that the coin uses for mining. The vCrypt algorithm is not entirely new mining algorithm, it is more like a variation of the Scrypt-N algorithm, though you are not able to mine vDinar with regular Scrypt-N miners.
Unfortunately there seems to be no binary version of the ccMiner for for Vcrypt, because it seems that the GitHub source of the Veles miner fork of ccMiner is incomplete and many people are having trouble compiling it by themselves. That is why we have compiled a 32-bit Windows binary of the miner with VC2013 and CUDA 8.0, it supports Compute 3.0, 5.0 and 5.2 and should work with pretty much any more recent Nvidia GPU. Do note however that the vCrypt algorithm is pretty heavy on the CPU, so you may have trouble achieving maximum hashrate if you have a slower dual-core CPU like the commonly used Intel Celeron processors for GPU mining rigs.
Performance wise you can expect something like 900-950 KHS from a GTX 1080 Ti, 700-ish from GTX 1070 Ti, 450-500 from GTX 1060, but that is only if you have a high-end CPU. With a slower processor such as Intel Celeron G3930 for example you might be getting just a fraction of the actual hashrate, because of the slow processor performance and the miner maxing out the CPU usage. You can try running multiple instances of the miner for better results and also feel free to play around and experiment with different launch settings to see if this might improve the situation with performance and share your findings, but again, have in mind that to get good performance with vCrypt on a multi-GPU mining rig you will need a really high-end CPU.
Raven (RVN) is an interesting coin that has been under the radar for many people up until recently when it got hyped and the interest in it has grown seriously in the past days. Initially the coin was only CPU mineable, then a ccMiner version with support for the X16r algorithm used by the coin was introduced for Nvidia miners by tpruvot however that miner has been a bit troublesome for many users due to power spikes and mining systems rebooting, so people had to reduce TDP or downclock and suffer performance loss in order to mine stable. Fortunately there is a new improved miner available now – ccMiner Enemy 1.03 that offers better performance and more stable mining with higher TDP and clocks (still depending on your hardware).
The ccMiner Enemy 1.03 fork for Raven (RVN) mining is available only as a 32-bit Windows binary for the moment and is compiled for CUDA 8, it supports the X16r algorithm used by RVN as well as X17. For better performance the latest 390.xx drivers from Nvidia are recommended, so make sure you are up to date. If you are mining Raven (RVN) or had plans to do so, but were set back by the problems from the initial miner you should definitely try the new release as it should handle much better. AMD miners are still unable to mine Raven as there is no compatible X16r miner available yet, though there is a substantial bounty for anyone willing to make one.
