Around May 2025, I completely rebuilt my PC to upgrade from an Intel i9-9900K. I have spent the last year fighting a frustrating issue: a heavy, disconnected "resistance" on my mouse cursor during gaming. Today, I finally found the root cause, or a major contributor.
Backstory: I initially built a full AM5 system with a Ryzen 7 7800X3D, hoping to eliminate frame drops during intense team fights. Day one was incredible. Every day after, my aim felt completely off. My cursor felt entirely disconnected from my hand.
After two months of frustration, I blamed the new AMD platform. I switched back to a fresh Intel build. Day one felt decent, but the floaty feeling immediately returned on day two.
Over the year, I tried every safe fix possible. I adjusted BIOS settings, altered Windows power plans, and tweaked Win32 Priority Separation. Nothing worked.
Today, I hopped into Apex Legends firing range and my aim suddenly felt perfect. My cursor was pixel-perfect and tracked my hand flawlessly. Then I noticed I had forgotten to turn on my wireless headset. The exact moment I switched the headset on, the sluggish, floaty aim instantly returned.
Seems my PC suffers from severe interference issues when handling multiple wireless devices. To fix it, I used an old HyperX MixAmp to convert my wireless headset into a traditional wired headset. The floaty cursor feeling is completely gone.
Disclaimer: This won’t work for most people, but if you are fighting unexplained input lag, try gaming with only one wireless device connected to see if it resolves your issue.

This subforum is for advanced users only. This separate area is for niche or unexpected lag issues such as electromagnetic interference (EMI, EMF, electrical, radiofrequency, etc). Interference of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction (ECC) latencies like a bad modem connection, except internally in a circuit. ECC = retransmits = lag. Troubleshooting may require university degree. Your lag issue is likely not EMI.
