A small toolkit.
A better gaming session.
Simple inputs, visible formulas and results you can understand. These tools run in your browser without an account.
Download and upload Mbps, idle ping, jitter and loaded latency.
Mouse sensitivity converter
Convert linear sensitivity using DPI and verified game yaw scales.
FREE BROWSER TOOLRefresh cadence test
Measure animation callback cadence in your current browser.
FREE BROWSER TOOLMouse event rate test
Observe mouse events delivered to this browser during movement.
FREE BROWSER TOOLPacket loss result calculator
Interpret sent and received packet counts from a test you ran.
FREE BROWSER TOOLMeasured bottleneck comparison
Compare repeatable FPS runs before and after lowering resolution.
FREE BROWSER TOOLUpgrade value calculator
Compare entered benchmark gains against your real upgrade cost.
eDPI calculator
Keep a sensitivity record within the same game.
DPI × sensitivity. Identical eDPI across different games does not guarantee the same rotation: each game can use a different scale, input mode and FOV.FPS → frame time
See the time budget behind your frame-rate target.
1,000 ÷ FPS. This is frame duration, not total input lag. Rendering queues, your display and input devices add other delays.Inspect a real frame-time CSVGame download planner
Plan a download around your next session.
GB × 8,000 ÷ Mbps. A theoretical transfer time at constant speed. Launcher limits, decompression, disk writes and changing bandwidth add time; installed size can differ from download size.Reaction warm-up
Activate the pad when it turns green. Mouse, touch and keyboard all work.
Five most recent successful attempts appear here.
Uncalibrated browser practice. Display refresh, browser scheduling and input delay affect the result. This is not a medical, esports ranking or hardware latency test.Small measurements beat random tweaks.
Write down your mouse settings before changing them. Translate a frame-rate target into its frame-time budget. Estimate the download window before starting a large install. Then check whether a single change improves the same repeatable session.
These calculators don’t predict FPS, lower ping or change your hardware. They help you plan and compare. Use official launchers, hardware settings and publisher instructions to apply changes.
