How to fix physics stuttering on a Ryzen 7 7800X3D?
When a crowd of enemies spawns, the physics collisions create this weird, floaty lag that is just pathetic for a high-end build. Even with the massive 3D V-Cache, the 7800X3D's clocks were fluctuating between 4.2GHz - 4.7GHz on certain instruction sets, causing physics engine delays of 20-45ms. I tried updating the chipset drivers first, but while it helped compatibility, the stuttering stayed—totally frustrating. I eventually enabled PBO in the BIOS, set the Curve Optimizer to -20 across the board, and locked my RAM at 6000MHz with FCLK at 2000MHz. A frame time analyzer showed the physics latency dropped from 25-45ms to 12-18ms. I actually blue-screened during the loading screen when I tried pushing -30, so -20 is my stability ceiling. CPU temps are between 65℃ - 78℃. I used a system snapshot tool to back up the PBO config so I don't lose these settings.
