🐭 You can tune the mouse to your hardware
If mouselook feels too slow or too fast after upgrading, open the launcher → Settings → Mouse → "Raw Input Scale" and adjust:
| Your mouse DPI | Try this scale |
|---|---|
| 3200+ DPI gaming mouse | 0.20 – 0.35 |
| 1600 DPI gaming mouse | 0.40 – 0.65 (default 0.5)
|
| 800 DPI mouse | 0.70 – 1.20 |
| 400 DPI office mouse | 1.50 – 3.00 |
Lower = slower, higher = faster. The same Settings tab also lets you tune Sensitivity, Smoothing, Stick Decay, Acceleration Curve, Deadzone Compensation, and Invert Y. Press Save & Close and relaunch.
What's new in v1.1.3 (mouse-calibration hotfix)
v1.1.2 introduced WM_INPUT raw-mouse plumbing in the SDK and applied a hardcoded divide by 8 on raw HID counts to match the magnitude of WM_MOUSEMOVE pixel deltas. The premise: an 800 DPI mouse → ~800 counts/inch vs ~96 pixels/inch from WM_MOUSEMOVE → ~8x ratio. What the premise missed: Windows applies pointer ballistics ("Enhance pointer precision") to WM_MOUSEMOVE deltas, inflating them at higher velocities. Raw input has no ballistics, so the same divider felt much slower in motion than the pre-raw pixel path. Community report — "mouse very, very slow in game".
Fix: tunable cvar instead of hardcoded divider
mnk_raw_input_scale (default 0.5) replaces the hardcoded /8. Surfaced in launcher Settings → Mouse → "Raw Input Scale" so you can dial to your mouse DPI + preferred feel. Existing mnk_sensitivity keeps its previous semantics — mnk_raw_input_scale is a separate pre-stage that normalises raw count magnitude to the pixel-delta scale that mnk_sensitivity was originally tuned for.
Update path
Existing v1.1.x users: launch PlayDownpour.exe and click the pill notification at the top — v1.1.3 installs in place. Your saves, settings, and warm shader cache are preserved. After upgrade, if mouselook still feels off → use the table above to tune it.
