Visit the [GP2040-CE Usage](https://gp2040-ce.info/usage) page for more details. ## Performance Input latency is tested using the methodology outlined at [WydD's inputlag.science website](https://inputlag.science/controller/methodology), using the default 1000 Hz (1 ms) polling rate in the firmware. You can read more about the setup we use to conduct latency testing [HERE](https://github.com/OpenStickCommunity/Site/blob/main/latency_testing/README.md) if you are interested in testing for yourself or would just like to know more about the devices used to do the testing. | Version | Mode | Poll Rate | Min | Max | Avg | Stdev | % on time | %1f skip | %2f skip | | ------- | ------- | --------- | ------- | ------- | ------- | ------- | --------- | -------- | -------- | | v0.7.10 | Xinput | 1 ms | 0.45 ms | 1.28 ms | 0.76 ms | 0.24 ms | 98.48% | 1.52% | 0% | | v0.7.10 | Switch | 1 ms | 0.41 ms | 1.22 ms | 0.73 ms | 0.24 ms | 98.52% | 1.48% | 0% | | v0.7.10 | HID USB | 1 ms | 0.42 ms | 1.24 ms | 0.73 ms | 0.24 ms | 98.53% | 1.47% | 0% | | v0.7.10 | PS3 | 1 ms | 0.52 ms | 1.33 ms | 0.82 ms | 0.24 ms | 98.38% | 1.62% | 0% | | v0.7.10 | PS4 | 1 ms | 0.55 ms | 2.38 ms | 0.91 ms | 0.31 ms | 98.19% | 1.81% | 0% | | v0.7.10 | PS5 | 1 ms | 0.55 ms | 2.38 ms | 0.90 ms | 0.31 ms | 98.20% | 1.80% | 0% | Full results can be found in the [GP2040-CE v0.7.10 Firmware Latency Test Results](https://github.com/OpenStickCommunity/Site/raw/main/latency_testing/GP2040-CE_Firmware_Latency_Test_Results_v0.7.10.xlsx) .xlsx Sheet.
