Bias contribution
Pulsar X2H (Wired)
0.08
Weighted contribution to aggregate Score from base-CPI bias. Higher is better.
Public benchmark snapshot
Gaming Mouse CPI Benchmark
temppal.gg publishes motion-capture-based CPI measurements for gaming mice. Each public record compares reconstructed physical sensor motion against raw HID reports and reports CPI bias, CPI jitter, and CPI drift.
Snapshot date: 2026-06-07. Physical mice: 10. Benchmark records: 13. Public tested conditions: 156 x 2 repeats (312 public condition runs, 1 h 44 min). Total recorded motion: 7 h 42 min across 1386 raw recordings. Raw bulk extraction is not permitted; cite this page or the mouse-specific pages instead.
Jitter contribution
Razer DeathAdder V4 Pro (MSync on)
0.41
Weighted contribution to aggregate Score from CPI jitter. Higher is better.
Drift contribution
Pulsar X2H (Wired)
0.11
Weighted contribution to aggregate Score from CPI drift. Higher is better.
Research basis
Built on Peer-Reviewed Mouse and Pointing Research
temppal.gg is not a review blog. It is a measurement site from YESLAB researchers whose prior work covers mouse sensing, pointing models, gain functions, button mechanics, aim-and-shoot behavior, and esports input performance. These papers explain why CPI fidelity, jitter, drift, and player-side tests are scientific measurement problems.
