Performance improvements of 1.28 compared to previous version (1.27): - Bitcoin Diamond +7-8%, Hex 4-5% and +3-5% for x16r/s, x17, bitcore, c11, sonoa, etc... Other changes: - Added --no-nvml switch to disable NVML monitoring (useful to reduce load on low end CPUs) - After several tests we recommend using intensity 22 on 1080ti cards on x16r algo (and perhaps others)
