Is memory frequency the cause of input lag in F1 25 on G.Skill?
When taking a corner at 300 km/h, there was this roughly 0.1s delay in steering response—absolutely fatal for a sim racer. My single-channel 8GB G.Skill Trident Z DDR4 3200 setup was hitting 92-98% bandwidth utilization during physics calculations, forcing the CPU to just wait for data. I tried killing all background apps, but that only gave me a 2% improvement, which just made me eager to try something more aggressive. I pushed the frequency to 3600MHz in the BIOS and tightened tRFC from 560 down to 480. In RTSS, frame times converged from a jittery 16-32ms to a tight 9-14ms, and the steering finally feels connected to my hands. I did get one BSOD during a stress test after the overclock, but bumping the voltage from 1.35V to 1.4V made it rock solid. RAM temps are now 48-54℃. Switched the performance mode in the motherboard center, and the 9-14ms frame time is holding steady.
