Use case

A gaming VPN, with the trade-offs spelled out

What a VPN can and can't do for ping, throttling, and DDoS protection. No marketing nonsense.

The honest physics of latency

A VPN cannot reduce the speed of light. Your packets still need to traverse the distance from you to the game server. Adding a VPN hop almost always means packets travel slightly farther than they would direct, which adds milliseconds.

The cases where a VPN reduces ping are specific: your ISP is routing your gaming traffic through a congested or geographically silly path, and the VPN server happens to be on a better route to the game server. This happens, but it's the exception, not the rule.

For everyone else, the goal is to add as little overhead as possible. That means WireGuard.

WireGuard is the gaming protocol

Fexyn Bolt runs WireGuard with userspace boringtun on Windows. The protocol has a small handshake, a tight data path, and stateless cryptokey routing — the technical minimum a VPN can do while still being encrypted. On a clean home connection, the latency cost over a nearby Fexyn server is in the single-digit milliseconds.

Fexyn Stealth (VLESS Reality) and Fexyn Secure (OpenVPN) add more overhead because they wrap the traffic in TLS handshakes for stealth or compatibility. Use Bolt for gaming. The other protocols are there for networks that block VPN traffic outright, which isn't the gaming use case.

Why WireGuard is fast

ISP throttling of game traffic is real

Some ISPs prioritise certain traffic types and slow others, especially on lower-tier plans. Game traffic gets caught in this when the ISP marks UDP traffic to gaming-specific port ranges as low priority during peak hours.

Inside a VPN tunnel, the ISP only sees encrypted UDP packets to a single endpoint. They can't single out your gaming traffic for shaping, because they can't tell what protocol is inside the tunnel. The trade-off is that they may then shape all your VPN traffic together. Your mileage will depend on which ISP and which plan.

The kill switch matters in competitive games

In ranked or competitive games where doxxing risks exist, a kill switch keeps your real IP from ever showing up in connection metadata. If the VPN drops mid-match without a kernel-level kill switch, the game client immediately reconnects from your ISP IP and the new session is logged that way. For streamers, that real IP can leak into voice-chat opponent logs.

Fexyn's WFP-based kill switch fires before the VPN handshake completes and survives reconnects. When the tunnel drops, the game client's reconnect attempt is dropped at the firewall layer instead of leaking out your real IP.

DDoS — what a VPN actually does

A consumer VPN doesn't make you DDoS-proof in any absolute sense. What it does is hide your real IP from the people who would attack it. If they only see the Fexyn server's IP, the attack hits Fexyn, not your home connection. The Fexyn server has upstream filtering that handles the volume; your home connection wouldn't.

The catch: this only works if the attacker only knows your VPN IP. If they already know your real IP from somewhere else (a Discord doxxing, an old game session log, a compromised friend who knows it), a VPN doesn't help.

Picking the right server

Two rules:

  1. Pick a Fexyn server near you. Distance to the VPN hop is the dominant cost in your ping.
  2. Test, don't guess. Connect, run an in-game ping check, switch servers, run again. The "closest" server isn't always the fastest because routing isn't geography-aware.

What we won't pretend

  • That a VPN improves your aim. It improves nothing about your input pipeline.
  • That every game tolerates a VPN. Some anti-cheat systems flag VPN IPs and queue you with other VPN users or kick you outright.
  • That you can use a VPN to play in regions you're not entitled to. Region-locked games check more than IP.
