hello

so, I was playing around with the /fill command and I decided to /fill an area with 20k tnt

(/fill 0 70 100 -100 70 -100 tnt) so I was filling a large area with TNT.

i then used this to ignite it all: (/fill 0 71 100 -100 71 -100 fire) 

doing this causes a lot of lag as you might expect, however, after a few seconds, it crashes to desktop. it seems to only be able to use 2 cores and 2 threads or 4 threads. it cannot seem to use all of my cpu which I'm guessing is causing the problem. 1 core will spike to 100% and then it crashes. 

my computers specs are as follows:

i7 10700k

32gbs 2400mhz ddr4

rtx 2060super 8gb

240gb m.2 nvme

1tb m.2

normally I would expect this to a standard problem with the game, however, when testing on my laptop:

i5 4310u, 

8gbs ddr3l

gt720m 

it does not do the same.  it seems to be able to use 100% of the cpu. and it does not crash. 

I'm interested to see if this is a problem with my computer or if it is a bug with 10th gen cpus or with the game?

many thanks

Lyndon
