Latency issues? It's not your hardware, so what modes were you playing, and does the lag appear to go away in widescreen or widescreen windowed?

They'll need more info to help you. I'm running an old computer from 2000 so it may be something network wise and not hardware related.

Please Help.
Thanks !

I didn't find the right solution from the internet.
