Is PBO the fix for Frostpunk 2 stuttering on 7800X3D?
This is just unbelievable—I bought a 7800X3D and I'm actually getting frame drops in a city sim. The 3D V-Cache was hitting 0.2-0.5% latency spikes during massive particle calculations, causing frame times to bounce between 14ms and 50ms. I wasted time updating every single driver in Windows, which did absolutely nothing for the physics lag, and I was honestly fuming. I finally went into the BIOS, set PBO to Enhanced, and manually set the Curve Optimizer to -20 while locking the RAM at 6000MHz. In RTSS, the frame time graph finally flattened out to a steady 12-15ms. I tried a -30 offset at first, but the game blue-screened after 10 minutes, so I backed it off to -20 for stability. CPU temps are chill at 65-75℃. After 4 passes of MemTest86 with zero errors, the game finally feels responsive, although the 3D V-Cache still feels finicky with certain simulation loads.
