hmm Stop your pron downloads (or any other) while playing PKR . For some reason it begins to lag if you dont have a free connection it seems. I ussually run torrents (for around half my broadband line leaving 2Mb free) but pkr begins to lag and risk lagging out of a hand if i dont cancel my down/uploads. I dont know if it downtrafic or up traffic thats sets it off as torrents go both ways.

Anyways I play on cake also , there it is no problem even if i almost use my full line.
