| Random Lag spikes
2 days ago, I started getting random lag spikes in all my games, even though internet connection if perfectly fine (Multiple speed tests were at around 4 mbps, I use ATT), however in games, such as counter strike source, I would frequently and randomly have a lag spike, and in the case of css, would get a sudden rise in choke from 0 to 20ish then it drops back down to 0 (no loss to little loss during the choke psike). This also happens in games such as guild wars, where I would get frequent random lag spikes (where my ping would skyrocket from a 66 to 2000+). But then it would revert back to a non-lagging state randomly for a few seconds-minutes. I scanned my comp for viruses, but didnt find any. Although I use a router, my internet connection is not wireless. There's no problems downloading or watching videos, but it only occurs in games. I can't figure out the problem. Can any1 help me out? thx in advance. |
