Far Cry 7 is stuttering in dense jungle areas on my Ryzen 7 9700X due to PCIe bandwidth limits. Any fix?

Using a top-tier architecture like the 9700X only to have it stutter in the jungle is just ridiculous—the mismatch between the hardware and the game's optimization is a joke. When rendering massive amounts of vegetation, the motherboard's PCIe lanes were seeing momentary voltage drops around 1.1V, creating an abnormal latency of 20-35ms between the CPU and GPU. I tried enabling Low Latency mode in the drivers, but while the input felt slightly faster, the frequency of the frame drops actually increased—a total waste of time. I ended up updating the BIOS to the latest version and manually forced the PCIe speed to Gen4 instead of Auto, while also tweaking the memory mapping. In RTSS, the frame times collapsed from a chaotic 18-45ms range down to a steady 14-20ms, and the game felt about 30% smoother. The BIOS update wiped my EXPO settings, so I had to re-configure everything from scratch. CPU temps are now 68-74℃ and VRM temps are at 75-82℃. I backed up the config, and the controller voltage is holding steady at 0.95-1.02V.
