Boolean faster in blender 2.79 is there some settings i am missing?

I just tried a boolean difference operation involving a cube with 4 subdivision level on a simple text as a cutter and i got 24 fps showing in the viewport.

I then did the exact same setup in blender 2.93 and i barely have 8 to 9 fps, how come?

I used the fast algorithm to make it on par with 2.79b.
