VIVID 100 - unusable for FPS due to latency spikes

I have VIVID 100 with an Xbox One on a wired connection to a Superhub 2. FPS games such as Battlefield 2 and Rainbow 6: Siege are unplayable competitively because of lag spikes. This is something that has become a feature of our connection over the last few months. It wasn't perfect before, but now it has become a major issue. Here's a recent graph BQM

My speed tests put our connection pretty much on the average performance for a VIVID 100.

Is our experience typical of VIVID 100 or is there something spectacularly awry? If there's a problem, does anybody have a useful way to approach addressing it with VirginMedia?

Looks more like something is actually wrong rather than just congestion, since you don't usually see the green area jumping around so much.

You need too raise this issue on Virgin's own forum and wait for a rep to get onto it, something is physically wrong with your connection, latency should be constantly up and down like your's is.

This is what mine looks like with light upstream congestion

Keep us updated!

yeah looks strange, call or contact virgin, possible fault.

i thought i had recent problems as you suggested same package 100mb speeds fine but like you now and recently getting intolerable pkt loss latency treacle effect in FPS games i am getting a phone call monday from tech vm i will post but ive been test and monitoring this for weeks it definity has changes=d in last month prob due to december over sellingQuality Monitor on Virgin Media with rise in average latency and jitter at peak times for me now even when idle as in my graph this should be flat it was up to December
What is very telling now is the wide variation in the quality monitors recorded by Virgin Media customers now, perhaps highlighting local optical node issues (maybe affecting a couple of thousand in an area) through to routes onto the national core congesting. In short there appears to be no single overriding cause and that means even if DOCSIS 3.1 arrives to solve local DOCSIS based congestion more work and money will need to be spent on upgrading core infrastructure links and better peering.

how do you post & generate nice BQM link without the long code from thinkbroadband ??
