Just another observation… I lowered the max temp even further to 72 degrees Celsius using Afterburner and now the GPU utilization is about 75% when flying around and the fps went from about 30 to 22. Strange, with a higher max temp it is used at 100% all the time, lower temp decreases it to 75%??? At ground it goes up to 100% though. Seems like a mystery, you would need the source code to be able to explain that.
