The reason why you shouldn't play on 1.16 is because it will generate huge mc logfiles while standing near spawners.
I recreated the problem myself to show you what i mean.
While i was near my mobfarm for 10seconds i generated 8.000 info and almost 14.000 warnings.
When we look into the logfiles (can be found in %appdata% -> Roaming -> .minecraft -> logs) we can see that minecraft will write logfiles that goes into the GB sizes and your C driver capacity will slowly drop down to 0Byte.
To fix the problem just switch to version 1.14 (you will even get more fps)
