Rocket League depends on timely physics updates. A low average ping can still hide latency variance or packet loss that causes rubber-banding, delayed touches, and sudden corrections.
Run the Rocket League ping test and compare median latency, the P10–P90 range, and missing replies. PartyPing probes are not Psyonix servers; use the result to shortlist directions, then confirm with the game's connection indicators and network graphs.
Use `Recommended` for the nearest practical region. For cross-region parties, remove any direction with loss or a clearly slow member before comparing the remaining regions. US-Central, Middle East, and South Africa are shown as unsupported because PartyPing has no corresponding probe.
Default, STS, and CSTS control input buffering. They may make irregular delivery feel smoother, but they do not reduce distance or route latency. Fix loss and large variance first, then compare buffer modes under the same network conditions.
