Can ClashX be used for gaming?

Yes, but you must enable TUN mode. Games use UDP protocol, and system proxy mode can only proxy TCP traffic, unable to cover games. TUN mode works at the network layer and can proxy all traffic including UDP.

Will game proxy increase latency?

It depends on node quality. Using IPLC/IEPL dedicated line nodes, latency increase is only 5-15ms, almost imperceptible. Regular relay nodes may increase 50-100ms. It's recommended to use url-test to automatically select the lowest latency node.

Can ClashX accelerate Steam downloads?

Yes. Add Steam-related domains to proxy rules and downloads will route through proxy nodes. Note the bandwidth limits of proxy nodes; it's recommended to use nodes supporting large traffic. Domestic Steam doesn't need proxy.

Do Genshin Impact/Honkai Star Rail and other HoYoverse games need proxy?

Domestic version doesn't need it. International versions (Asia/US/EU servers) need proxy if playing from mainland China. Configure split routing rules to route international server domains through proxy while domestic server domains connect directly.

Why is the game still laggy even with proxy?

Possible reasons: 1) Node latency is high, switch to IPLC/IEPL dedicated lines; 2) TUN mode not enabled, game UDP traffic not routed through proxy; 3) DNS resolution is slow, configure game DNS for direct connection; 4) Node bandwidth insufficient, switch to higher bandwidth node.

What's the difference between IPLC and IEPL?

IPLC is international dedicated line, IEPL is ethernet dedicated line. Both bypass public internet, offering low latency and stability. IEPL typically has larger bandwidth, suitable for gaming and video. Price-wise they're similar, both more expensive than regular relay.

ClashX Gaming Acceleration Setup Guide [2026] Complete Low-Latency Proxy Configuration

Why Games Need Dedicated Proxy Configuration?

Games have completely different network quality requirements compared to regular internet usage:

Latency Requirement

< 80ms

Packet Loss Rate

< 1%

Protocol Support

TCP + UDP

Regular system proxy mode can only proxy TCP traffic, while games heavily use UDP protocol (such as voice chat and real-time position synchronization). This means system proxy is basically ineffective for games, and you need ClashX's TUN mode to achieve true global proxy.

Common Gaming Proxy Scenarios

Playing overseas servers from mainland China (LOL US server, Valorant, PUBG international), playing domestic servers from overseas (Genshin Impact domestic, Honor of Kings), Steam/Epic store acceleration, cross-region multiplayer matching.

TUN Mode: Essential for Gaming

Gaming acceleration must enable TUN mode. Reasons:

                                UDP Support — TUN mode works at network layer, can proxy both TCP and UDP traffic
Global Coverage — Game client needs no separate configuration, all traffic automatically goes through ClashX
DNS Control — Prevents game domains from being incorrectly resolved to high-latency servers
Leak Prevention — Games cannot bypass proxy and connect directly, ensuring all traffic uses optimal route

                            

For detailed TUN mode setup steps, refer to ClashX TUN Mode Setup Tutorial.

Low-Latency Node Selection

Game proxy has extremely high requirements for node quality. Here's the gaming performance of different line types:

Node Selection Tips

FPS games (Valorant, CS2) require latency < 80ms, choose IPLC/IEPL. MOBA games (LOL) can tolerate around 100ms. Turn-based/strategy games are latency-insensitive, regular nodes work fine.

Game Split Routing Configuration

First download ClashX, enable TUN mode, then edit the configuration file to add the following rules. For detailed syntax, refer to config.yaml Complete Guide.

DNS Optimization

Games are sensitive to DNS resolution speed. Incorrect DNS resolution can connect you to remote servers, adding tens of milliseconds latency.

dns:
  enable: true
  enhanced-mode: fake-ip
  fake-ip-range: 198.18.0.1/16
  fake-ip-filter:
    # Game domains don't use fake-ip (prevent connection issues)
    - "*.battlenet.com"
    - "*.blizzard.com"
    - "*.riotgames.com"
    - "*.leagueoflegends.com"
    - "*.playvalorant.com"
    - "+.stun.*"
  nameserver:
    - https://dns.cloudflare.com/dns-query
    - https://dns.google/dns-query
  nameserver-policy:
    # Domestic games use domestic DNS
    "+.tencent.com": "https://doh.pub/dns-query"
    "+.netease.com": "https://doh.pub/dns-query"
    "+.mihoyo.com": "https://doh.pub/dns-query"

⚠️

fake-ip-filter is Important

Some games' anti-cheat systems detect connection IP. If using fake-ip, games may detect abnormal IP and disconnect. Add these game domains to fake-ip-filter to ensure real IP usage.

Performance Tuning Tips

1. Lower Tolerance Value

Set url-test node group tolerance to 30ms (default 150ms), making ClashX more aggressive in switching to low-latency nodes:

- name: "🎮 Gaming Acceleration"
  type: url-test
  tolerance: 30  # Switch if latency difference exceeds 30ms
  interval: 120  # Test every 2 minutes

2. TCP Fast Open

Some proxy protocols support TCP Fast Open, reducing handshake latency. Enable in node configuration:

proxies:
  - name: "🇯🇵 Tokyo-IPLC"
    type: ss
    server: jp.example.com
    port: 443
    cipher: aes-256-gcm
    password: "your-password"
    tfo: true  # Enable TCP Fast Open

3. Disable Unnecessary Rules

More rules mean longer matching time. For gaming, simplify the rule list, keeping only necessary game domain rules and fallback rules.

Latency Testing Methods

                                ClashX Built-in Speed Test: Right-click ClashX menu bar icon → Benchmark, view each node's latency
In-Game Latency: Most games show latency/Ping in settings, enable for real-time monitoring
Terminal Ping Test: ping -c 20 game-server.com to check average latency and packet loss
ClashX Connection Panel: View actual latency and traffic for each connection in Dashboard

                            

Frequently Asked Questions

Q: Can system proxy mode be used for gaming?

A: No. System proxy only proxies TCP traffic, games heavily use UDP. Must enable TUN mode to proxy game traffic.

Q: Do domestic games need to disable proxy?

A: No need to disable. In split routing rules, set domestic game domains (tencent.com, netease.com, mihoyo.com) to DIRECT connection, ClashX will automatically route domestic traffic directly.

Q: Game suddenly disconnects mid-play?

A: Likely caused by automatic node switching changing IP. Solutions: 1) Use manual selection (select) instead of auto-test (url-test); 2) Increase tolerance value; 3) Use fallback group instead of url-test.

Q: Steam download speed slow?

A: Steam downloads use CDN, can configure separate high-bandwidth node for Steam download domains. Or temporarily switch to direct connection during downloads.

Q: Can't connect to Valorant server?

A: Valorant's anti-cheat Vanguard is sensitive to proxy. Ensure: 1) Add Riot domains to fake-ip-filter; 2) Use TUN mode instead of system proxy; 3) Node IP not blocked by Riot.

Q: Which region's nodes are best for gaming?

A: Depends on game server location. Asia servers choose Japan/Hong Kong/Singapore; US servers choose Los Angeles/San Jose; EU servers choose Frankfurt/London. Choose node closest to game server.
