In my case dropping down to 1440p w/o DLSS and letting my TV do the AI upscaling allows me to also raise my T-LOD to ~300. What is most interesting is that my system runs best with my monitor @60hz, MSFS vsync on at 30fps and rendering at full 4k with all settings at ultra and T-LOD at 300 I like hardly ever get a studder over 500ft. It’s like my PC goes into total zen mode and everything is buttery smooth. If I turn on DLSS, it becomes a studdering mess and sometimes crashes (on SU9).
