Slow mouse move even with Settings.MoveMouseDelay=0

-Im on java 11 java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
-MacOS 10.13.6
-1.1.3 SikuliX

Even with Settings.MoveMouseDelay=0 mouse movement is slow.
If i change Settings.MoveMouseDelay=3 its working and goes slow as it supposed
but with 0 its not fast.

When it was going fast, with 3 points of region was super fast... I mean it was making a blur the cursor....now i can see the points it goes...

I run it from ide and from export jar... still the same..

any suggestion?

the simple test:

Settings.MoveMouseDelay = 0

ao = Region(304,159,1,1)
a1 = Region(294,406,1,1)

while True:
    ao.click()
    a1.click()
