An example is i can say live chess is now easier to login, and is more stable then msn messenger. :)
Live Chess - Less lag, better connection?

No lag for sure. No disconnections, but need to play more games to know for sure.
Thanks erik. Keep up the good work.

great to hear!

Just played a game of blitz whilst downloading in the background, no appreciable lag and the pieces were moving nice and crisply.
Opponents clocks still running backwards sometimes in non-delay games.
Ha ha ha, you can't understand this, can you? In spite of countless explanations.
About the original question, it appears to me that piece movement is different. I can't explain, but my eyes get tired with the new animation/piece movements. I find it quite bad, the old one was just perfect.

DISCONNECTS!
I played a 30min+5 live game today and got several momentary disconnects, as did my oponent. I haven't played much before the change so I can't comment on any differences.

It seemed better yesterday but today it looks like it's going back to normal. We'll see in a few more days.

Played a few games last night...It seemd much faster and stayed connected....Much much better, now it is usable! Thanks chess.com, i might start playing live chess a little more now!
Great work!

I agree with Funandnice. http://www.chess.com/forum/view/help-support/site-is-too-slow
Seems like normal... then again, I've never been d/c before, so that's not saying too much. At any rate the chat rate does seem faster. Thanks.
