3080TI 26% gpu usage 20fps at FL350 and elsewhere (NOT hardware related)

So I have been experimenting and I realized that by putting my graphics options preset down to low end my frames went to 45fps. I put my settings back to ultra like it was before. I then restarted my sim and I then teleported back to the exact position at the exact same altitude on the same route and my frames at the same settings were at 55fps. So clearly I’m assuming this is more a performance degradation rather than a cpu to gpu inbalance?
