Horrible Lag

[kat truewalker]

ok

i'm using a Dell XPS Laptop on a home network wireless connection. I have Windows 7 and use the desktop launcher...the laptop is high spec with plenty of memory. The problems only occurred tonight and everything was fine this morning,

The lag tonight is the worst I have ever experienced....I have all the latest up to date drivers but I dc when i fight dark hart with graphics issues - it freezes and resets and i then dc...

I have heard someone mention that it may be a problem with my intel drivers?

i contacted live chat who couldn't really help so does anyone have any ideas?

Thanks...
