my GPU usage (and thus hashrate) has always fluctuated like a small sine wave from 99% - 90% , after this patch, they all stay a straight line 99% , so that's way more than a 3% increase in hashrate for me.
What's weird, mine went from 90%-96% to 96% straight but the added performance adds 1.5C to the temperature, I might have to clock down a bit to get tot he previous 90C stable line, which means I am forfeiting the benefits of the above optimization. At least I use less energy, the Earth will thank us all...You're still being more efficient and saving money by using less energy. His optimization made your load a constant 96% instead of 90%-96%, so your GPU has less time to cool. You should still get as many hashes as you did before, if not more, plus less energy
