Well my frame rate issue has returned. It only seems to happen when I have been flying for a couple of hours. I have been monitoring CPU & GPU rate and my GPU never gets above 25%. The CPU averages 60%. I've looked up reasons for this but nothing seems to fit. I have altered power settings to Ultimate. I am perplexed. Why isn't FG utilising the GPU there is plenty of CPU.
Forgot to say when I quit FG and then restart my FPM goes back to 60. When I first started using this computer I was getting FPM of 120+.
