Gonna be real with you I tested a bunch of popular VPNs and the numbers don't lie. On average a good VPN can add 20 to 50 ms latency which is noticeable in fast-paced games. But some claim certain protocols or servers actually cut ping and stabilize connection. The thing is those numbers depend heavily on your location, VPN server location, and network setup. I suspect the whole 'VPN reduces ping' hype is more about perception than reality, unless you find a server close to your ISP's route. In most cases it's a trade-off between privacy and performance and most gaming VPNs sacrifice speed for hiding your IP.
