What is Mouse Acceleration?

Mouse Acceleration adjusts the speed of your cursor based on how quickly you move your mouse. Faster movements result in the cursor covering more distance on-screen, while slower movements yield more precise control.

How long has Mouse Acceleration existed?

Mouse Acceleration has been around since the early days of graphical user interfaces (GUIs), with implementations in operating systems like Windows and macOS dating back to the 1980s. The concept was introduced to enhance user experience by making cursor movement more intuitive and efficient. Over time, the feature has evolved, leading to tools like Custom Curve that offer more advanced and customizable acceleration settings tailored to individual preferences and gaming needs, which has been around for around 5+ years.

What is the difference between Windows Mouse Acceleration and Custom Curve?

Windows Mouse Acceleration offers terrible and uncustomizable acceleration settings, while Custom Curve allows for precise customization of the acceleration curve, giving you more control over how your cursor responds in different gaming scenarios.

Is Mouse Acceleration recommended in competitive FPS games?

Mouse Acceleration, when properly customized with Custom Curve, is highly recommended for competitive games like Valorant. It provides players with a personalized aiming experience, improving precision and increasing the aim skill ceiling which are both crucial for high-level play.

What are the advantages of using Mouse Acceleration in FPS games?

Using Mouse Acceleration with Custom Curve enhances precision and consistency. It lets you fine-tune acceleration to match your gameplay style, resulting in better aiming accuracy and control during fast-paced action.

What is Custom Curve, and how does it improve aim?

Custom Curve lets you build a personalized mouse acceleration profile – you control exactly how cursor speed scales with hand movement. Instead of a one-size-fits-all setting, you shape the response to match your playstyle, which translates to more consistent crosshair placement in any FPS.

Is Custom Curve allowed in competitive games?

Yes. It was developed in collaboration with the FACEIT Anti-Cheat Division and is safe to use in Valorant, CS2, Fortnite, Warzone, Halo, Tarkov, Roblox, Call of Duty, and every other major title. It modifies your mouse input at the driver level – no game files are touched.

Why choose Custom Curve over Windows mouse acceleration?

Windows applies a fixed, non-configurable acceleration curve that most gamers find unpredictable. Custom Curve replaces it with a fully adjustable graph where every point is under your control, so the response feels natural rather than fighting against you.

Does it work with any mouse?

Yes – any USB or wireless mouse works. The acceleration curve is applied at the software level, independent of your mouse brand, sensor, or DPI setting.

Can I create different profiles for different games?

Absolutely. You can save multiple profiles – a fast, aggressive curve for arena shooters and a slower, precision-focused one for tactical games like Valorant. Switching between them takes one click.

How does a custom acceleration curve compare to raw input?

Raw input gives you a fixed, linear response. A tuned acceleration curve adds a dynamic layer: slow movements stay precise for micro-adjustments, while fast flicks cover more distance. Many players find this raises their effective skill ceiling once the curve is dialed in.

Does mouse acceleration work outside of FPS games?

Yes. Players use it in MOBAs, battle royales, and even desktop productivity. The curve adapts to any scenario where you want precise low-speed control and fast high-speed traversal.

What makes Custom Curve different from other acceleration tools?

It offers the deepest graph editor on the market, live preview of your curve while you play, per-game profiles, and a community of 50,000+ players sharing their settings. No other tool gives you that combination of precision and community support.

How do I get started?

You can experiment with the graph editor yourself, or save time by purchasing personalized settings above – we'll build a curve matched to your sensitivity, mouse, and the games you play.

How does the converter work?

Drop your Custom Curve file onto the converter. The format is detected automatically. Click convert and your new file downloads instantly. Nothing is stored on our servers.

Is this converter free?

Completely free, no limits, no account needed. We built this because we needed it too.

Will my curve feel the same after conversion?

The converter preserves your sensitivity curve shape in both directions. That means the core feel of your aim stays the same. However, any advanced settings that are exclusive to one version will not carry over. For example, Custom Curve 4 settings like per-point weights or hand modulation are lost when converting back to 3, and any Custom Curve 3 specific metadata is replaced with defaults when converting to 4.

What is Custom Curve 4?

Custom Curve 4 is a complete overhaul. You get per-point weight control for smoother curves, left and right slope modes, hand acceleration modulation, independent horizontal and vertical sensitivity, angle snapping, output smoothing, bias curves for diagonal movement, and a built-in polling rate override. Everything Custom Curve 3 can do, plus a lot more.

Can I convert back to Custom Curve 3?

Yes, the converter works both ways. Keep in mind that Custom Curve 4 exclusive features will be lost when going back to 3, since Custom Curve 3 does not support them. Your core sensitivity curve is always preserved.

Is my data stored anywhere?

No. Your file is processed in memory and discarded immediately. Nothing is saved, logged, or tracked.
