How to solve 3D V-Cache scheduling lag on AMD Ryzen 9 9950X3D?
It's honestly ridiculous—using a flagship 9950X3D and still feeling stutters in Valhalla's towns. The 3D V-Cache is a monster, but this older game's threading is a mess, causing the OS to dump threads onto the non-cache cores. Latency jumped from 40ns to 110ns instantly. I tried using third-party software to lock the cores, but the system became unstable and BSOD'd every ten minutes. Pure frustration. I eventually went into the BIOS, enabled PBO Enhanced Mode, set the Curve Optimizer to -20 across all cores, and dropped my RAM from 6000MHz to 5800MHz just to ensure the FCLK was absolutely stable. OCCT ran for 4 hours with zero errors, and my 1% lows in towns jumped from 42 FPS to 68 FPS. I tried a more aggressive -30 offset at first, but that led to random restarts while idling. Backed off to -20 and it's golden. CPU temps are 62-74℃ with a 175W peak. Exported the voltage curves to my motherboard profile, and the game feels incredibly snappy now.
