Hey Optiminer, any chance you could fix the Windows miner to allow for multi-GPU configs (nVidia)? Currently it completely saturates the CPU, and ends up crashing the rigs within minutes...

Principally it should work with multiple NVidia CPUs. I suggest to try running it on Linux.
Fixing the high CPU usage will require rewriting the kernel in CUDA which is a major change, so will take time.
The miner only supports stratum mining at the moment.
