Controller issues

So, I’ve been using my Xbox Wireless Controller for about four years now and it’s always been reliable. However, over the last two months, every single game I play—whether it’s NBA 2K, Madden, FIFA, Need for Speed, or 2K Proving Grounds—suffers a massive FPS drop from 60 down to a stuttering 15 or 20.
Everything worked perfectly before, so I have no idea why it’s causing this much lag.
I even installed new drivers, which were completely useless, and the issue persists.
Whenever we host a game night, I bring it along; it works fine on everyone else's PCs, but when it starts acting up on mine, the night ends early.
I don't believe the controller itself is the culprit; it feels more like a USB issue. I've already tested it in ten different ports.
What should I do? I'm losing my patience.

Is it just that one controller acting up, or are the others giving you grief too?

I honestly can't recall when I had both plugged in; I didn't bother testing this second one because I hadn't realized the issue was actually with the controller itself.

I'm asking because it feels weird that the controller could be the culprit... before jumping to conclusions about the PC itself or some background process hogging resources, like a Windows Update running in the background...

As soon as I request him and switch back to the keyboard, the FPS returns to normal

Looks like you aren't the only one dealing with this. It’s like everyone who owns this specific controller is hitting the same wall... I’ve seen plenty of threads online about it, but honestly, nobody seems to have actually fixed it yet.

So, are you running this on a laptop or a desktop? What kind of specs are we looking at?

A10, 12GB of RAM, GTX 760, and a 240GB SSD.
But frankly, those specs are irrelevant if the entire system was functioning perfectly just two months ago.

Any news on Windows updates or Logitech drivers lately? A bunch of people have been linking this to the PC slipping into some kind of "halfway" sleep mode... one guy even mentioned he’s fine while he’s moving his mouse, even if it's just idling while he plays Mortal Kombat on a controller, but the second the mouse stays still for a minute or two, his FPS absolutely tanks 🤷

Maybe dig through your sleep mode or power saving settings to see if anything looks "off"

Impressive diagnosis; I certainly wouldn't have thought of that. Now we have to dig for a solution, given that all sleep modes and power savers have been disabled—it is likely buried within some program or utility.
