The answer to which game accelerator is best isn't on a marketing page — it's in three things you can measure: latency, packet loss and route type. On the same international route, packet loss at peak hours is usually worse than in the early morning; and two services both marketed as accelerators may not travel the same path at all, because dedicated-line forwarding and a direct public-internet connection are entirely different routes. Below we take the three apart, then hand you a comparison method you can reproduce yourself.
How Latency and Packet Loss Affect Game Feel
Latency is the time a packet takes to make one round trip, written as RTT and measured in milliseconds. There is a fairly consistent set of rules of thumb for how it affects control: under 30 ms round trip is essentially imperceptible, 30 to 60 ms is acceptable, 60 to 100 ms makes the gap between input and feedback clearly noticeable, and above 100 ms shooters, fighting games and MOBAs — anything that depends on precise timing — start to suffer. These bands are rules of thumb only; tolerance differs by genre, and turn-based and single-player games are far less latency-sensitive than real-time competitive ones.
Latency has a physical floor that no acceleration method can break. Light travels through fiber at roughly 200,000 km per second, which works out to 200 km per millisecond. A one-way distance of 2,000 km means a 4,000 km round trip, so the theoretical floor is about 20 ms — and once you add router forwarding, queuing and detours, the real figure is only higher. So a claim like 5 ms from mainland China to a European server can be dismissed outright: it isn't that the route is poor, it's that physics doesn't allow it.
Packet loss is a different matter. Most real-time competitive games run on UDP, and dropped packets are not retransmitted — what you see is missing actions, rubber-banding and abilities that fire into nothing. TCP does retransmit, but the head-of-line blocking that comes with it makes latency spike, which players feel as stutter. Even 1–2% packet loss is perceptible in situations that demand continuous input, yet it often barely shows up in average latency — which is exactly why watching ping alone leads to wrong conclusions.
One more metric that gets overlooked is jitter, the amount latency fluctuates. A route that averages 60 ms but swings wildly usually feels worse than a steady 80 ms route. Measure it continuously rather than writing down a single number.
Where Accelerators and Proxies Differ
Many people treat the two as the same thing, but they differ in what traffic they handle and how much control they have over the path. A plain HTTP or SOCKS5 proxy mainly handles TCP, while games lean heavily on UDP — hit an implementation that only forwards TCP and the traffic simply falls through, which shows up as web pages loading fine while the game refuses to connect. Even when a proxy supports UDP, it usually just carries traffic from your device to an overseas exit node over the public international gateway, so peak-hour congestion is still peak-hour congestion.
A game accelerator works differently: it identifies game traffic separately, forwards it over UDP, and controls all three legs of the path — entry, cross-border segment and exit. Common protocol-level implementations include Shadowsocks, VMess, Trojan and VLESS, plus the QUIC-based Hysteria2 and TUIC. The first group solves encryption and transport shape; the last two are more aggressive about congestion control and loss recovery and tend to hold up better on lossy links — though carriers may rate-limit them as UDP, so only real measurements count. A protocol name promises nothing on its own; the path decides the outcome.
All three are sold as acceleration, but the routes below perform very differently. Use this table as a reference for what a given service is actually offering.
| Route type | Path characteristics | Latency stability | Packet loss | Best for |
|---|---|---|---|---|
| IEPL dedicated line | Fixed dedicated line from entry to exit; never touches the public international gateway | Small swings at peak hours | Low loss on the cross-border segment | Competitive matches, long-term play on a fixed server region |
| Relay | Entry → relay node → exit; the cross-border segment runs on an optimized route | Moderate, depends on relay node quality | Depends on the relay route | Everyday play, voice chat alongside updates |
| Direct | Client connects straight to an overseas exit node over the public internet | Noticeable swings at peak hours | Rises when the international gateway is congested | Occasional use, off-peak hours |
What you pay for with a dedicated line is predictability: the path is fixed and doesn't compete with ordinary international traffic for gateway capacity, so peak-hour performance stays close to what you see in the early morning. The value of a relay depends on the quality of the relay node itself — a good one comes close to a dedicated line, a bad one is worse than going direct. Direct is the simplest, but the most exposed to time of day. None of the three is universally better; it either matches the hours you play and the server region you target, or it doesn't.
Pick a Route by Game Server Region
First work out where the server is, then decide whether a dedicated line is worth it. Distance sets the latency floor; a route can only cut detours and packet loss, never physical distance.
Hong Kong, Taiwan, Japan, Korea and Southeast Asia servers
Physical distance is short, so a direct connection or an ordinary relay already delivers usable latency. What matters for these regions isn't speed but peak-hour stability: once the international gateway congests, a direct connection that worked fine shows both higher latency and packet loss at the same time. The way to judge it is to test once at peak hours and once in the early morning and see how wide the gap is. A small gap means direct is good enough and there's no reason to pay for a dedicated line.
Europe and North America servers
The distance is long, so the latency floor is high to begin with. Take roughly 10,000 km one way from mainland China to the US West Coast: a 20,000 km round trip puts the theoretical fiber floor around 100 ms, and forwarding and detours add more on top. That means Europe and North America servers can never be low latency — what you can do is push packet loss and jitter down so latency sits steadily where it belongs. This is where a dedicated line earns its keep, because it avoids the queue at the public gateway.
Middle East, South America and Africa servers
These regions usually have no direct route, and a public-internet connection tends to go halfway around the planet. A relay is close to mandatory, and it needs to sit in a sensible location — otherwise the extra distance from the detour pushes real latency well above the theoretical figure. The way to judge it is straightforward: look at which regions the route hops through. The more detours, the further real latency drifts from the floor.
Check the server first, then the route
The same game may run Asia, Europe and North America servers at once. Confirm which server you're targeting before switching anything, or the numbers you measure before and after aren't comparable and changing routes tells you nothing.
A Comparison Method You Can Reproduce
Most hands-on tests published online can't be reproduced because the variables weren't controlled. Follow the order below and you'll get comparable results of your own.
- Fix the variables. Same device, same testing tool, same local network. Numbers taken after switching devices or Wi-Fi can't be compared directly.
- Test in separate time windows. One round at peak hours (roughly 20:00 to 23:00), one in the early morning. The gap between the two is the route's resistance to congestion.
- Watch three metrics. Average latency, jitter and packet loss. Throughput only matters when downloading game updates and has little to do with how play feels.
- Cross-check. A speed test reports latency to the test node, not to the game server. Compare it against the in-game latency display or a system ping; a large gap means you picked the wrong test node.
- Log at least three days. A single result is heavily influenced by temporary congestion; only a continuous record reveals the pattern.
In practice, these few habits help you avoid the most common sources of error:
- ✅ Run three tests in the same window and take the median, not the best-looking one.
- ✅ Record packet loss separately instead of staring at average latency.
- ✅ After the numbers, play an actual match. How it feels is the final verdict.
- ❌ Drawing conclusions from a single speed-test screenshot.
- ❌ Comparing numbers from different tools and different nodes.
- ❌ Assuming peak hours are fine because the early-morning test looked good.
A speed-test node is not a game server
Many speed-test tools pick the nearest node by default, so what you measure is latency to your local carrier's facility — a good-looking number with no reference value. To test a game route you have to select a node in the target region manually, or simply use the in-game latency display.
When it's actually worth turning on
Not every game needs one. If you only play on servers in mainland China, or you play single-player and turn-based titles that aren't latency-sensitive, the benefit is close to zero. The cases genuinely worth considering: you play long-term on international servers and peak-hour packet loss already affects your inputs; the game depends on a long-lived connection where a disconnect is expensive, such as dungeons, ranked matches and team fights; or you run voice chat and streaming at the same time and need game traffic separated from everything else.
Conversely, if you only log in occasionally for a reward, or your local network is already dropping packets, fixing the local network is the better investment. No route can rescue an unstable connection — swapping accelerators just moves the problem somewhere else.
On cost: the ¥9.9 monthly plan with 60GB is a reasonable way to try it for a month; heavier players can look at ¥18 with 250GB or ¥28 with 500GB; and if your usage is irregular, data packs start at ¥158, last until used up and never expire, so there's no end-of-month reset to worry about. All three monthly plans reset their data monthly on the activation date, and mid-term upgrades are prorated by remaining days — see plans and data packs for the full comparison.
Order of judgement: first where the game server is, then how bad peak-hour packet loss is, and only then price. Distance sets the floor, the route sets stability, and price only means something once the first two pass.
A few common traps
DNS leaks misroute your server region
The proxy is on, but DNS queries still go to your local carrier, so resolution comes back based on your local location. In games this can mean the launcher assigns you to the wrong region, or updates download from an unsuitable CDN node. The fix is to let the client handle DNS resolution, or enable full traffic capture in a client that supports TUN mode.
Global proxying can be slower
Push all traffic through a single route and games, voice chat, system updates and video fight over the same bandwidth. The sensible approach is split routing: game processes over the accelerated route, voice and updates direct, matched by domain or by process. Most clients support rule mode, the setup cost is low, and the difference afterwards is obvious.
Traffic capture differs by platform
On Windows it's usually a TUN virtual adapter capturing all traffic, which covers UDP and is the friendliest to games; Android captures through the system network service API and requires authorization; iOS and macOS use system network extensions with a different configuration model; consoles (PlayStation, Xbox, Switch) generally need it done on the router, or a PC sharing its connection with the console. The same subscription can behave differently across platforms, so re-test after switching.
Pick the wrong protocol and newer isn't steadier
QUIC-based protocols have an edge on lossy links, but some networks rate-limit or interfere with UDP. If you find things slower after connecting, switch back to a TCP-based protocol for a comparison rather than concluding the route is bad. A protocol is just a tool; whether it works depends on how the network you're on treats it.
Bottom line: which game accelerator is best depends on where your server is and how much packet loss you see at peak hours, not on the adjectives in the marketing copy. Use the same device, test in separate time windows, and log latency, jitter and packet loss for three days — the answer surfaces on its own.
