I used to think the same thing until I tried a VPN myself while playing multiplayer games late in the evening. In my case it didn’t magically lower ping all the time, but I did notice fewer random connection drops and more stable matches on certain servers. I think it depends a lot on your internet provider and where the game servers are located. Some people mainly use VPNs for privacy while gaming too, especially in competitive games where players don’t want their connection details exposed. While reading more about how VPNs work in gaming situations, I also found some discussions here: https://toggle.org/airdrop and a few explanations there helped me understand why connection quality sometimes changes with different routes. I’d say it’s worth testing if you often deal with unstable servers or regional connection issues.
