Weird Glitch in My Racing Game Only Happens When I Use a Controller, Not Keyboard

I’ve been playing this indie racing game on my PC for a couple of weeks now, mostly with my keyboard and mouse setup. Everything runs smoothly, but when I switch to my Xbox controller, I get this odd lag where the car stutters and briefly freezes every 10-15 seconds during a race. I tried updating the controller drivers and even reinstalled the game, but the glitch persists only with the controller plugged in. I’m running Windows 10 on a mid-range gaming laptop, and my USB ports are all 3.0. Has anyone else experienced performance issues tied specifically to controller input? Could it be something with the game’s controller support, or maybe a USB polling rate issue? I want to keep using my controller because it feels way better for racing, but this stutter is killing the experience. Any ideas on what to check or how to fix it?
