What a response curve does
A curve maps your mouse speed to stick deflection. With Linear, deflection equals input — move the mouse at half speed, the stick sits at half. With any shaped preset, the mapping is bent: the same mouse movement produces a different stick position depending on where on the curve you are. This matters because the game's aim assist is tuned for stick behavior, and the curve decides how smoothly your input passes through the aim-assist zones.
Inputize ships five presets, each defined by five control points (input→output at 0, 25, 50, 75, 100 percent). They are not marketing names — here is exactly what is stored in the engine for each one:
The presets, honestly compared
| Preset | Control points (input → output) | Feel | Best for |
|---|---|---|---|
| Linear | 0→0 · .25→.25 · .5→.5 · .75→.75 · 1→1 | Neutral, 1:1 | Baseline; aim assist engages untouched |
| Aggressive | .2→.45 · .5→.72 · .8→.92 | Fast launch — small moves, large stick | Snappy tracking, higher-DPI mice |
| Smooth | .3→.08 · .6→.35 · .85→.75 | Gentle start, slow build | Fine, slow aim; holding angles |
| S-Curve | .2→.05 · .5→.5 · .8→.95 | Calm center, strong edges | Popular pick for most shooters |
| Exponential | .15→.02 · .4→.12 · .7→.45 | Very slow center, explosive finish | Sniper-style micro-corrections |
Reading the table: Aggressive reaches 0.45 output already at 0.20 input — a quarter of your mouse movement buys almost half the stick throw. Smooth is the inverse: 0.30 input produces only 0.08 output, so the stick barely moves during small mouse travel. Exponential is the most extreme sleeper — the first 40% of input yields just 12% output, then it rockets to full.
Which one for which game
Warzone / CoD: S-Curve or Aggressive. CoD's aim assist is strongest near the stick center; aggressive launch keeps the assist engaged without overshooting the target bubble. Start with Aggressive at lower intensities if the default feels twitchy.
Apex Legends: S-Curve. Apex rewards controlled tracking over instant deflection; the calm center of S-Curve minimizes the assist-thrashing that happens when you exceed the stick zone at speed.
Fortnite (controller builds): Linear or S-Curve. Fortnite's assist is sticky; shaping it aggressively can double-stick when the helper pulls one way and the curve another. Linear is the honest baseline, S-Curve if you want a slight boost at the edges for build-fights.
Snipers / careful aim: Exponential or Smooth. Slow center means tiny mouse corrections produce tiny stick moves — the crosshair makes micro steps instead of the coarse jumps you get with aggressive launch.
The honest caveat
Curve choice interacts with the smoothing preset and with your mouse DPI, so nobody can hand you a 'correct' curve. The method that works: pick S-Curve, play one session, note whether you overshoot (switch to Smooth) or undershoot (switch to Aggressive). The response-preview graph in the app shows the actual input→output line while you drag, so the mapping is visible before you ever queue into a match. And remember: Linear intensity is locked — a 1:1 curve has nothing to adjust, by design. When you switch presets, your sensitivity number meets a different response — the DPI and sensitivity guide covers how to retune in the right order.
