AHK runs slow in win10

[just43go]

I just recently upgrade my OS from win7 to win10, and my ahk run speed drop dramatically.

My script was just using PixelGetColor and if color matches, then click on mouse.

pixelgetcolor, X5, 170, 1025
if X5 = 0x73DFD6
{
sendinput, {0}
sleep, 150
}


When I was using win7, I disable the desktop composition, which helps a lot. However, I wasn't allowed to disable desktop composition in Win10.
it was excuting the script every 150ms in Win7, and now it's like every second in Win10 which causing a big problem.
Does anyone knows how to increase the speed?
Thanks
