Ok, so the story goes... Got vista (ultimate, x64), combined with halo and a few drivers. got my pc working comfortably. one month's hassle free gaming and now this... when i log on, or play campaign, it works fine. but online gaming allows 5 second bursts of movement. even on low ping servers. as i said, i had been playing for about a month, on my usual servers, and it worked fine. i tried the normal things; defrag, update graphics drivers, reduce resolution, kill background tasks, check router/ports/wireless; heck i even cleaned my pc physically. And still nothing. as the title says, vista has been ticking away, updating itself. oh and i ran through firewall and defender, they're kooky [ok] too. god i miss halo. somebody help! here's my dx diag stuff anyway. cheers!
