We are working on native ARM support for Windows.
While there is no definite date for the release of the native Windows ARM version of FL Studio, the changes to the FL Studio code base we did to support native Apple Silicon (also ARM) processors will help to speed things along.
Until then x86 emulation on Windows ARM is excellent in terms of comparative performance with Apples Rosetta 2 and also has good reliability with FL Studio as tested.
