Cloud Gaming Readiness Test

Free in-browser readiness check for xCloud, GeForce Now, PS Remote Play, Steam Link, Amazon Luna and other cloud-gaming services. Measures latency p95 with 30 round-trip pings, downstream throughput against a known-size payload, and probes the codec support that streaming pipelines need (H.264, H.265 and AV1). Each service gets a clear Ready / Playable / Poor verdict with a reason.

How to use

Connect to the network you will play on

Cloud gaming readiness is sensitive to where you measure. Run on Wi-Fi if that's where you'll play; switch to wired Ethernet if available for a baseline.

Click Start measurement

A 30-sample latency probe runs first, then a throughput payload. Total time is about 5–8 seconds depending on connection.

Read the per-service cards

Green Ready means all thresholds met. Orange Playable means one threshold is slightly missed. Red Poor means two or more are missed — try a wired connection.

Re-test if results look off

Run several times — Wi-Fi and shared connections fluctuate. Take the median across 3 runs as your real number.

Measurement

Measures round-trip latency to this origin (HTTP) and to a STUN server (UDP — same protocol as cloud-gaming traffic), plus downstream throughput. Maps the result to per-service thresholds. Run on the network you plan to play on.

Data Saver is active — your browser is throttling background fetches, so the throughput number will read low. Disable Data Saver in browser settings for an honest reading.

Service recommendations

Each service is checked against its public minimum-bandwidth and target-latency requirements plus any codec needed by the streaming pipeline.

Hardware-decode codec support

Cloud streams encode in one of these codecs. AV1 unlocks GeForce Now Ultimate; H.264 is the universal floor.

FAQ

Why does the latency seem low?

We measure to our own origin, which gives a floor — actual cloud-gaming round-trip will be higher because data centres are often farther. The p95 we show is a useful proxy because if it's already over budget here, it will only get worse against a real DC.

Why does AV1 matter for GeForce Now Ultimate?

GFN Ultimate streams AV1 to compatible browsers because AV1 is more efficient at the same bitrate, which translates to better visual quality on the same network. Without AV1 the service falls back to H.264, which is fine but lower quality.

Does this work on the Steam Deck browser?

Yes. Latency and throughput are network-level so SteamOS Chromium reports the same numbers as desktop Chrome on the same Wi-Fi.

Why is the throughput lower than my speed test?

Speed-test sites use multi-stream parallel TCP. We measure a single-fetch payload, which is closer to what a streaming codec uses. The number will usually be lower; this is by design.

Can I trust this to predict GeForce Now Ultimate quality?

It's a readiness check, not a guarantee. Real perceived quality also depends on game type, peak network jitter, and the GFN data centre you connect to. Our verdict tells you whether the network and browser can support the service at all.
