Ummm nope ping is caused not just by the net it can be caused by a lot of thing's. and last i heard pc was locked so dont kill the fucken messenger
Ping is the latency between your computer and a server. More specifically, how long it takes for the server to send packets to your computer and for your computer to respond. Ping isn't caused by the net. It's affected by it.
And no the fps is not locked on PC. You can use a simple program like fraps to prove that.
