Low fps still present in later phases with block cluster rendering on.

not necessarily a bug, but rather something that may be out of nomancracker's control. a while ago, I found that I had low fps with block cluster rendering on, and thought it was my graphics card struggaling. now, after testing it with flywheel, i found the fps to be unchanged. I decided to look at my GPU usage, and found it was less than 20% usage. then, I checked cpu usage. that was maxed out. on a ryzen 7 3700x. at least, it was maxed out on a single core/thread. because minecraft is mostly singlethreaded, the primary thread gets pegged when dealing with a lot of block clusters. but, the issue disappears if block cluster rendering is off. I am curious as to why block cluster rendering primarily on the CPU instead of the GPU.
to reproduce: summon the witherstorm in phase 5 or later with block cluster rendering on (with or without flywheel)
log: 2022-08-09-1.log.gz
flywheel: active, default configuration.
PC specs in case you were wondering:
Ryzen 7 3700x
32 GB DDR4 3400
Rx 6600
If you go to the flywheel compat config and enable block cluster instancing following a game restart, you should see a big difference. The only reason the config is off by default is because block colours such as grass appear as white.
