fps drop at low gpu/cpu

[dizzy321]

hi i have a problem,
i have a little patch that only reaches 10%cpu and 40% gpu load max. the java process running praxislive however reaches well over a 100% and only runs on a single core. strangely, the less animated squares i have (adjusted by p2d-2 property amt) the lower the fps drop. at 30 squares i get the expected 60 fps.

there could be a compatibility issue with relatively new hardware and linux, but i have no clue.

amd ryzen 5 7600
geforce rtx3060

does anybody have an idea?
here is the patch
