Engine Architecture, Yaw & FOV Comparison: Deadlock vs Fortnite
| Specification | Valve Deadlock | Fortnite (Ballistic & Battle Royale) |
|---|---|---|
| Game Engine | Source 2 Engine | Unreal Engine 5.5 |
| Horizontal Yaw Constant | 0.044° / count | 0.5555° / count |
| Competitive Field of View (FOV) | 100° (Third-Person Source 2 Camera) | 80° (80° Locked (BR) / 103° (Ballistic FPS)) |
| Server Tick Rate / Polling | 64Hz Sub-Tick | 30Hz–60Hz |
| ADS / Scope Scaling Rule | Deadlock uses 2× Source yaw (0.044°/count), meaning Deadlock sensitivity is exactly 0.50× your CS2 sensitivity. | Fortnite percentage sensitivity (e.g., 6.5%) uses 0.5555° per percentage point. |
Frequently Asked Questions — Deadlock to Fortnite Conversion
How do you convert Valve Deadlock sensitivity to Fortnite (Ballistic & Battle Royale)?
To convert Valve Deadlock sensitivity to Fortnite (Ballistic & Battle Royale) at the same mouse DPI, multiply your Deadlock sensitivity by 0.079208 (or divide by 12.625000). This derives from the exact engine yaw ratio: Deadlock uses 0.044° per mouse count (Source 2 Engine), whereas Fortnite uses 0.5555° per mouse count (Unreal Engine 5.5).
What is 1.1 Deadlock sensitivity in Fortnite (Ballistic & Battle Royale) at 800 DPI?
At 800 DPI, a Deadlock sensitivity of 1.1 equals 0.0871 in Fortnite (Ballistic & Battle Royale). Both settings produce an identical 23.62 cm (9.30 inches) physical 360-degree turn on your mousepad.
Does FOV difference between Deadlock (100° (Third-Person Source 2 Camera)) and Fortnite (80° (80° Locked (BR) / 103° (Ballistic FPS))) affect converted sensitivity?
Converting by yaw ratio (0.0792×) locks your 3D 360-degree physical rotation distance (23.6 cm/360°) for consistent gross arm/wrist muscle memory. However, because Deadlock renders at 100° (Third-Person Source 2 Camera) and Fortnite renders at 80° (80° Locked (BR) / 103° (Ballistic FPS)), micro-flicks near the center crosshair may feel slightly faster or slower on screen depending on camera focal length.
