Why FOV changes how fast aim feels
With your cm/360 fixed, a full turn costs the same hand travel at any FOV. What changes is how many degrees sit between your crosshair and the edge of the screen. Valorant shows 103 degrees across a 16:9 screen and CS2 shows 106.26, so a flick to the screen edge covers 51.5 degrees in one and 53 in the other.
A wider view packs more of the world into every part of the screen, so reaching a point you can see takes more hand travel. That is why a correctly converted sensitivity can feel slow in a game with a wider view and twitchy in one with a narrower view, even though the turn is identical.
What each game lets you set
- Valorant: fixed at 103 degrees across 16:9.
- CS2: no FOV slider. 106.26 degrees across 16:9, and 90 across the full width at 4:3 stretched.
- Apex Legends: a slider from 70 to 110, measured across a 4:3 screen, so on 16:9 you see more than it says: 90 shows about 106 degrees and 110 roughly 124.
- Deadlock: Camera FOV from 75 to 90, measured across 16:9, default 90.
- Fortnite: fixed at 80 in normal play. The FOV sliders only change the view while you sprint.
The Valorant to Apex and Deadlock to CS2 converter pages work through what those differences mean for a converted sensitivity.
The same number can mean different views
Games do not agree on how to measure FOV. Some quote degrees across a 16:9 screen, others across a 4:3 screen, so a 90 in one game and a 90 in another can be quite different views. Compare them in the same measure before deciding one game is wider than another.
