You apparently don't understand how computers and the internet work. No there is no such client nor will there ever be. Lag can be anything from data packets being dropped, memory leaks, too little ram, too little video ram....you name it. There is no "perfect" client.
You was incorrect, a less lag client prolly can be done. Prolly, it still don't exist. The point of most of your post in this topic say "You're a noob, you don't know how pc work, ram and lag and other stuff are thing you can't understand so shutup."
I hardly see something correct in this words, so, the only thing correct you've sayd was prolly the "Ther's no such client". Or at last, we don't know of anyone that have coded it for now.
You should just say what's usefull, next time, and avoid all other words that adds lots of other useless and wrong things to your posts. You'll see no one will bother you then.
now, for the Op, there are several client out there. No one optimized for the ram, but you could try the lighter one for your pc, just trying all those.
Watchout from phishing, anyway. Download only clients largly tested.
