Unable to play input lag suddenly on i7 12700k with xcalibur 4000mhz, 1060 3gb, 144 hz (up to 170hz after two years)
Hello, I'm trying to solve this unusual issue that has appeared suddenly. Three weeks ago, I purchased an i7 12700k, a Z690 Gigabyte gaming GPU with DDR4, and an ASUS ROG LCE 360 water cooler. The rest of my system consisted of RAM sticks (2x8GB T-Format Xcalibur 4000MHz), a 1060 3GB SSD, and a monitor that was overclocked to 144Hz at 170Hz for two years. Everything functioned perfectly for three weeks, running smoothly and quickly.
However, without any changes to hardware or software, I began experiencing strange input lag—like playing at 75Hz instead of the expected 170Hz. The mouse movements felt sluggish, making it hard to aim accurately in games such as CS:GO, Valorant, or Overwatch. Interestingly, my FPS stayed stable across all titles, but the overall fluidity was noticeably reduced, as if I were using a 60Hz monitor.
So far, I've ruled out several possibilities: the graphics card (even with integrated graphics still performed okay), the SSD, internet usage, Windows versions, and RAM configurations. I've tested the RAM with MemTest86 for 30 minutes without any issues.
Regarding my monitor's overclocking, I removed it to check if that helped, but the input lag persisted. I'm also considering whether the monitor itself might have degraded after two years of overclocking.
For the processor, I've been running it at 4.7GHz and 4.0GHz (ECores) with 1.32V and auto VCCSA for extreme mode. Temperatures stayed below 60°C, and power consumption never exceeded 60W. I'm unsure if these settings affected my system negatively.
I've updated my BIOS to the latest version and tried it with default settings, but the input lag remains. I also reverted to an older configuration, which slightly improved the lag but not enough. I still have significant input lag issues.
If needed, I can provide a video or image of my current setup in the BIOS.
I'm not sure what might be causing this problem—whether it's the processor, motherboard, monitor, or something else. Please let me know if you can help. Thank you for your time.
