AimDeltaFix

Fixes mouse sensitivity feeling slower at higher framerates in R.E.P.O.

What's the bug?

The camera smoothing in CameraAim.Update() uses Quaternion.Lerp(current, target, num3 * Time.deltaTime) in a feedback loop. At 60fps that lerp factor is ~0.83, so the camera snaps almost instantly to where you're aiming. At higher framerates like 700fps, it drops to ~0.07 per frame — the camera barely moves each frame and it feels like your sensitivity got turned way down.

How this fixes it

When camera smoothing is off and no override is active, the lerp is skipped entirely — the camera just snaps to your aim target regardless of FPS. When smoothing is on, the lerp factor is replaced with 1 - Exp(-num3 * Time.deltaTime) which gives proper frame-rate independent exponential decay.

Dev fix

The issue is on line 213 of CameraAim.Update(). Easiest fix for smoothing off is to just assign the target directly (base.transform.localRotation = quaternion). For smoothed mode, swap num3 * Time.deltaTime with 1f - Mathf.Exp(-num3 * Time.deltaTime).
