Optimizing AMD Ryzen 7 7800X3D cache for Kingdom Come Deliverance II
Absolute game changer! Switching PBO from Auto to Enhanced mode boosted my minimum frames by 20 in dense town crowds. The 7800X3D's massive cache should be a cheat code, but at stock speeds, memory latency was bouncing between 65-72ns, causing tiny hitches during complex AI processing. I initially tried lowering the RAM frequency for stability, but that actually cost me 5 FPS—a frustrating bit of trial and error that taught me timings are where the real gains are. I tightened the memory timings from 36-36-36 down to 30-34-34 and set a Curve Optimizer negative offset of 20. Cinebench R23 single-core scores went up by 4%, and the 1% Lows jumped from 42 to 61 FPS. I did get some random BSODs at idle when I first applied the negative offset, but dialing it back to -15 made it rock solid. CPU temps stay between 62-74℃. Monitoring shows the cache hit rate is way higher, and frame times are locked at 5.1-6.4ms.
