Hi, I tried the new physics, I love it, it's so rich and make the gameplay so far away from arcade.. well, what a job with realism these last years !
I like the fact that the ball goes more up & down considering the timing and positioning , we put it more in the net if we are not precise - which was rare in TE2013.
The accelerations now are really accelerations : we can successfully accelerate only if we have time, and when we do it really tricky for the opponent. So, the "acceleration" button will not replace the "normal shot" button anymore.
The serve has more importance than before.
Slices have nice & rich directions.
I just see one or two things stranger than before :
I'm not sure but I feel that a.i slices are very hard to catch, and often make a winner, which I rarelly see in real tennis (except Federer at Wimbledon

).
And maybe the hitbox is sometimes too large specially with defensive player, maybe it could be replaced by easier run or positioning (tonicity, auto-positioning ...) (am I clear enough?..) but it's only visual so its not so important.
One question : will the new physics & a.i be in the last TE2013 upgrades? I have a cheap laptop and I'm not sure TE4 will work on it..
Thanks !
