In fact, apple can't fix interface lags and jerking arrows, input delay, delay in drawing the interface in the new macbooks pro 16 inch from the moment of their release - it is unacceptable that the device for so much money can not peform normally - any cheap laptop does not have input delay and cursor jerking/stuttering - if you switch to discrete graphics all problems disappear - well, apple is indifferent to these problems, it has long ago turned into a money making company - since the release of this laptop, everyone I know who has the same laptop has the same problems with it - the tone of the reports is open about this problem - and still there is no fix and apple does not want to recall these broken laptops - then that it earns money and does not care. The problem is actually in the video card intel hd graphics 630 - when you do not do anything with the interface - its frequency is 0 - and when you open a new window or print a video card does not have time to increase the frequency from 0 to 300/400 mhz - apple need not lower the frequency to 0 - but they can't do it because then the autonomy will suffer - hence the conclusion - there is a design error of a new macbook or an unoptimized ui which at the moment requires a lot of resources - there are no such problems in windows via bootcamp. But, it's not really our problem we paid a lot of money for a properly working device.

yes, the interface ceases to slow down when switching graphics - well, the question is why should I pay for the laziness of the developers with the laptop autonomy by using radeon videocard

the cursor stuttering bug is still not fixed for MacBook 16 inch BIG SUR 11.2 - Apple doesn't seem to care about us - it hasn't been able to fix the bug since the macbook pro 16 inch was released

I have tested MacBook Pro 16 inch on Big Sur 11.2 - only the release date is 2020 november (my laptop 2019 december) - and it has no Slow UI, input, cursor stuttering lags - . Apple must replace such notebooks - but instead - the authorized service center said that everything is fine all the tests pass
