Why does Starfield drop to 48 FPS during dense cloud traversal on AMD Ryzen 5 9600X due to scheduling?

While traversing dense clouds in Starfield, the physical engine's particle calculation caused a scheduling bottleneck, with E-Cores at 100% load and P-Cores idle. I tried adjusting the Windows power plan to Performance mode, which improved P-Core response but did not fix the E-Core physics latency. I used GamePP BIOS Load Line Voltage Adjustment Wizard to set Load Line to L3 and adjusted VCCSA voltage to 1.23V. Cinebench R23 multi-core score improved to 34200, and cloud rendering frame rate stabilized at 88-105 FPS per RivaTuner.
