Using GPU for preview timeline

Hi everyone

I'm using premiere Pro 2019 to make a little vacation video of 10minutes in 1080p

When I publish the video its perfect but having some difficulties to see my progress cause of the timeline preview even in 1/8. After 5 secondes of preview, it's lagging. Have to stop, wait 3 sec and play again

I know that my hardware is not made for Adobe :

Win10 on SSD

AMD A8 7600 3.10ghz

8 gb Ram

Video files on HDD

And NO GPU

Was asking if premiere use GPU for the preview or if ts only cpu and ram?

I could buy a little GPU if better

Thx for your help
