Genoil, the developer of the Ethminer fork with Nvidia CUDA support (source) has been actively working and there have been some othere people contributing code, so we have compiled an up to date Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 fo windows 64-bit and is for CUDA 6.5 as previous versions were compiled for CUDA 7.5, so there could be some performance differences between the different versions. The latest version comes with some optimizations that should increase a bit the performance when using the CUDA mode with the miner, however there are also some differences as you may need to manually specify the number of GPUs to use if you have multiple cards using the cuda-devices command line parameter if the miner fires only on one device. Additionally to get better performance you can try adding the following command line parameters to the ethminer:
For OpenCL:
--cl-global-work 16384
For CUDA:--cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo
The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.
