Use the same mouse DPI in both games
Convert Siege horizontal sensitivity to Kovaak’s cm/360
Use a Siege-to-Kovaak sensitivity calculator
Match Siege FOV to Kovaak’s FOV if the calculator asks for it
Enter the calculated Kovaak’s sensitivity into Kovaak’s hipfire sensitivity
If using ADS in Siege, convert each ADS multiplier separately
Keep Windows pointer speed at default and mouse acceleration off
Verify the result by checking if a 360° turn in Kovaak’s matches Siege
Adjust only if your DPI or in-game FOV differs between the two games
