Why does my Far Cry gameplay stutter in dense jungle areas?

Exploring the jungle felt broken because rendering stuttered constantly. I tried moving the RAM to a different slot, but it caused a system hang, which was frustrating. I used the GamePP BIOS Load Line Voltage Adjustment Wizard to raise voltage from 1.20V to 1.25V and set timings to 16-18-18-36. MemTest86 showed zero errors over 6 loops, and GamePP sensors confirmed stable 3200MHz operation at 45-50°C, fixing the lag.
