Insane Ping spikes (fix?)

So for the past week, I’ve been getting ping spikes between 60-220ms in Marvel Rivals on the Frankfurt server. It’s super laggy and stutters constantly, making Spider-Man basically unplayable.

I’ve tried everything—changing DNS, resetting my router, all that—but nothing works. What’s weird is that other people seem to have no issues playing on the same server, and all my other games run perfectly fine with no lag.

Is it the server? My connection? Something else? I’m out of ideas.
