Is PCIe bandwidth causing input lag in Tekken 8?
Trying to land a critical combo and feeling that slight screen tear is absolutely lethal in a fighter. The PCIe 3.0 lanes on the Soyo SY-King Dragon H510M were showing 5-12ms of scheduling latency, making the inputs feel disconnected. I tried enabling Low Latency mode in the drivers, but gaining 3 FPS didn't fix the input lag, which was incredibly frustrating. I ended up going into the BIOS, forcing the PCIe link speed to Gen3, and disabling every single onboard peripheral I wasn't using to clear the bus. Monitoring with RTSS, the frame time variance shrank from 12-30ms to a tight 8-12ms. I actually locked myself out of my keyboard for a bit because I disabled too many USB ports, but after recalibrating the boot order, it worked. Board temps stayed around 45-52℃. Input lag is finally gone.
