Should I tweak PBO curves for AMD Ryzen 7 7800X3D?
When the screen fills up with hundreds of soldiers, my FPS would tank from 90 down to 40, which was honestly anxiety-inducing. The 3D V-Cache on the Ryzen 7 7800X3D was struggling with the heavy physics load, and voltage offsets were causing the clock speeds to swing violently between 3.8-4.7GHz, choking the rendering pipeline. I tried enabling Windows Game Mode, but a 3 FPS gain doesn't mean anything when your 1% lows are still in the gutter. I eventually went into the BIOS, set PBO to Manual, and applied a -30 curve optimizer offset to cores 0-3, while locking my RAM at 6000MHz. HWInfo showed that the core voltage fluctuations were squeezed into a tiny 1.05-1.12V range, and the drops vanished instantly. I did have a couple of random restarts during idle after the first tweak, so I had to back the offset off to -20 to get it stable. Now the CPU stays between 62-68℃. After testing across multiple scenes, the cache scheduling is finally optimized. All system parameters are now set.
