How do I fix the input delay on Ryzen 7 7800X3D in Tekken 8?
During high-stakes matches, I noticed that even though my frames were locked at 60 FPS, there was this infuriating 'sticky' feeling to my inputs. The 7800X3D's V-Cache should theoretically crush this, but HWiNFO showed my clock speeds were bouncing wildly between 4.2GHz - 4.8GHz, which felt like a scheduling nightmare. I started by disabling every single background service in Windows, but the response time only improved by about 1ms—basically a waste of time. Frustrated, I dove into the BIOS, enabled PBO, and set the Curve Optimizer to -20 across all cores to stabilize the boost clocks by lowering the voltage. Checking RTSS frame time graphs, my input latency tightened from 12-18ms down to a rock-steady 7-9ms. I actually tried a more aggressive -30 offset at first, but the system rebooted three times right on the loading screen, so I backed it off to -20. Now temps sit comfortably between 62℃ - 68℃ with an even load distribution. Verified the voltage curve in Ryzen Master and the settings are finally sticking.
