Shadow’s stream adapts to available bandwidth. Run a test while playing a lightweight game or moving the mouse rapidly to see if latency spikes.
| Myth | Reality | |------|---------| | “1 Gbps internet is overkill for Shadow” | Bandwidth isn’t the bottleneck—latency and jitter are. A stable 50 Mbps fiber connection often beats an unstable 1 Gbps cable connection. | | “Speed tests are always accurate” | Many ISPs prioritize speed test traffic. Shadow’s test bypasses this by using the actual streaming protocol. | | “Low ping in games means good Shadow performance” | Game ping (ICMP) ≠ Shadow streaming latency. Shadow uses UDP real-time video encoding, which is more sensitive to jitter. |
If your Shadow speed test shows poor results, try these before canceling your subscription:
If your speed test shows great ping but Shadow lags when someone else watches Netflix, you have Bufferbloat. Your router is filling its buffer queue. shadow pc internet speed test
You cannot use the default speedtest.net server set to "Auto." You must force the test to target Shadow’s specific data centers.
Here is the most common failure point: Bufferbloat.
You have 500 Mbps internet, but the moment your roommate joins a Zoom call, your Shadow stream turns into a slideshow. That is bufferbloat—your router is holding onto data packets too long. Shadow’s stream adapts to available bandwidth
The Fix: Run the test at Waveform Bufferbloat Test (free).
Shadow provides a proprietary speed test inside its launcher (Windows/Mac). Do not guess your settings—use this tool.
Step-by-step:
Pro Tip: Run the test three times. Once at 9 AM (off-peak), once at 8 PM (peak hours), and once while someone else is streaming Netflix.
It is common to see speed test results on Shadow that are lower than the bandwidth you pay for at home. Here is why:
The "Two-Hop" Problem
When you run a speed test on Shadow, the data travels like this:
Server (Speedtest.net) -> Shadow Data Center -> Your Home Internet -> Your Shadow Client | Myth | Reality | |------|---------| | “1
Because Shadow streams the video feed to you, a speed test running inside the Shadow PC is actually downloading data and then trying to push it through the stream to your monitor.
