I think i fixed my issue. I am now getting 43-65 FPS flying low over new york city @4k ultra settings, LOD at 400, no DLSS, TAA, no frame gen, all traffic settings maxed out. With frame gen turned on with TAA i get 80 to 130ish FPS.
I adjusted 2 settings in the bios and one in Nvidia control panel. However, I believe the nvidia setting was the big hitter. I set low latency mode from auto to ultra in the MSFS profile.
In the bios i changed my cpu overclock mode from auto to profile 2 and i set the intel velocity thermal mode from auto to on. Now my asus bios spash screen displays an overclocked graphic. I think these changes probably didnt make much of a difference. My CPU was hitting 5.5ghz and now is hitting 5.7 and sometimes 5.8 (5.8 is the advertised OC).
I noticed on the flight sim fps counter my latency is now low teens vs 35+. My GPU utilization is hitting 99% vs before it was sitting around 25%. It still will sometimes drop to around 60% at times depending on the scene.
