even more bad news:

> it will not get better soon

with: canvas 800\*800 and 5000 of your ?items? ( i not read your code… )

our usual JAVA 8 Processing 3.5.3

 ![cpu_usage_processing353_newPC](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/c/c03ad5b6eb1371e79a234f3da43cb710e86b4514.png)

and now i try the JAVA11 version ( possible Processing 4.0.0 beta ) @sampottinger

 ![cpu_usage_processing400b_newPC](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/c/cedfb624d3b15b3aa71496364f58df1951eee8cf.png)

and same ( or even less ) FPS  
and i hoped it might be more ?efficient?  
( i not understand why the GPU usage value changed / 12% to 36% / )

so:

> processing is cooking on one burner?
