How to fix V-Cache instability in combat scenes?
The stutters are most brutal during fast dodges; it feels like the game is being pulled back in slow motion. With the 7800X3D's 3D V-Cache, if your memory clock and FCLK aren't perfectly synced during complex physics collisions, you get a sync offset of 12,0 - 18,0ms, which tanked my 1% lows from 80 FPS down to 35 FPS. I tried enabling 'Game Mode' in Windows, but that just gave me a measly 5 FPS boost while the hitches remained—totally illogical. I went into the BIOS and manually locked the FCLK at 2000,0 MHz and set the RAM to 6000,0 MHz for a clean 1:1 ratio. Using a latency analyzer, my memory latency dropped from 75,0 - 92,0ns to a crisp 62,0 - 68,0ns. I actually tried pushing it to 2133,0 MHz first, but that led to random BSODs until I backed off to 2000,0 MHz and bumped the SOC voltage to 1,2V. Temps stayed steady at 62,0 - 68,0C. After a three-hour stress test, the glitch is officially dead.
