Why R6 Siege and Fortnite numbers differ
Rainbow Six Siege runs on AnvilNext 2.0 and Fortnite on Unreal Engine 5. Fortnite numbers are 1.03× larger than R6 Siege numbers for the same hand movement, because Fortnite turns less per mouse count.
The in-game slider only takes whole numbers, so round the converted value. Aim-down-sight sensitivity is set separately.
Why does my converted sensitivity feel different?
- Field of view: a wider FOV makes the screen appear to move slower even at the same cm/360.
- Scoped and ADS aim: this matches hipfire only. Fortnite shows sensitivity as a percentage. Targeting and scope sensitivity are separate percentages on top of it.
- Mouse acceleration: if Windows acceleration or a mouse app adds it, the same movement turns a different amount depending on speed. Turn it off.
