fix: Improved performance on windows (#54) (#100)

In my testing, this have no negative impact on lost input anymore (after
fix in 0.3.0).

I haven't noticed any huge impact on performance in my tests, but may
not be in a performance-limited scenario. But has neither noticed loss
of input accuracy, so this feels like a safe change.
