JUST small example of bad transition and chunky animation. I really do not have so much time now to explain and to make a longer video.
That is just from first 20 sec of the gameplay video, the game on this stage is full with this, skipping frame, bad animation logic, and speed .. parasite movements that make the game to feel chunky.
There are a LOT even worst looking examples that I can give you but again.. now I do not have time to watch all PES 2020 videos and to make CHUNKY compilations. Maybe another day.
I know that are just Alphas and Betas builds, and maybe I'm just too critical but... I don't know.... the best PES ever.. can't have chunky animations, since once they prove us, that they CAN make animations right.
In PES 2018 the transitions and logical players movements were spot on.. so natural, it's gone since then. It's hard to explain you just... feel it.
