ye i spent a good few hours looking into this i think its a bad combo of TSR, Shadows and antialias slowing down the gpu, increasing consumption (wattage) and decreasing performance. TSR is def dx12 only optimized according to devs. Im on 4k screen and i think tsr struggles with it. Heres more info.

The goal of the TSR is to be a temporal upscaler that answer the anti-aliasing need of displaying unprecedented Nanite amount of details on screen, while accommodating enough GPU performance to entire renderer by rendering lower resolution than we were before, to in turn enable as many rendering feature as possible to produce the b…

Theres too many parameters some are poorly documented, maybe a few ui bugs too. For instance i think unreal insights gives some wrong fps timing depending where the threading sleeping happens, inside or outside the render frame, but its just a visual bug.
