Hello, I tested the minecraft 19w07a snapshot
except that the foxes are very well made (except for the eyes) there is a problem
rather serious (this is also the case in 1.13.2

I have a computer with an i3 7100, 8GB of ram DDR4 and usually I never have RAM overconsumption problems, usually minecraft only eats 1.5gb of RAM, but its eats me 2.5GB of ram and 80% of my processor, in 1.12.2 I had no such problem at all.

I think it's really a game problem and not mine.

thank you for your answer

hold this little comparison
