Why Fortnite and R6 Siege numbers differ
Fortnite runs on Unreal Engine 5 and Rainbow Six Siege on AnvilNext 2.0. R6 Siege numbers are 1.03× smaller than Fortnite numbers for the same hand movement, because R6 Siege turns more per mouse count.
Fortnite shows sensitivity as a percentage. Targeting and scope sensitivity are separate percentages on top of it.
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. Check R6 Siege’s own zoom settings.
- Mouse acceleration: if Windows acceleration or a mouse app adds it, the same movement turns a different amount depending on speed. Turn it off.
