There is a new official release of tpruvot’s ccMiner fork version 2.2.3 available (source) with new algorithms supported and additional improvements. The latest version brings support for Polytimos algorithm as well as support for the KeccakC algorithm, along with an optimized Keccak support for SM5+ GPUs, based on alexis78 improvements. The official Windows binaries for the new version are compiled for SM 3 Nvidia GPUs and CUDA 9 only (require driver version 384.xx or newer) and are available in 32-bit as well as 64-bit version.
After a quick test of the KeccakC support we can suggest that you might want to try increasing the intensity over the default value for your GPU for some improvements in terms of performance, though even then there is still a faster fork of ccMiner with KeccakC support. If you are interested in mining CreativeCoin (CREA) that uses the KeccakC algorithm with best performance you might want to check out this ccMiner fork for optimal performance.
