- Added parameter to enable or disable driver-specific optimizations on Nvidia GPUs. Use -nvdo 1 (the default is 0) to enable the optimizations. This won't change hashrate (or will change it only slightly) but can make the cards more stable depending on the concrete Nvidia driver.
What driver version or versions was this coded for? What are the driver settings the optimizations affect if you dont mind dropping some knowledge? What ever they are they seem to work for stability.
