Lag and rubber banding - Battlefield 3

Thanks for the suggestions guys.

The only relevent tweak I found in: http://sonsofvalour.forumotion.co.nz/t687-battlefield-3-tweaks-and-fixes that I hadn't tried before was trying to disable ECN packets, never really done anything.

I had previously tried running only the required services and programs along with the minimum hardware but the problem persisted. 

Finally caved in and done a fresh install of windows which seemed to have fixed the problem, unfortunately I haven't been able to isolate what was conflicting with BF3 but I can presume it was probably software related. I'm still getting lag spikes every 10 or 20 minutes but I think that's down to the problem a lot of people are having with punkbuster, either way it's better every 10 minutes than once a second.

I have since re-installed most of my programs I had before without the problem resurfacing, so maybe it was an older version of something.. We'll never really know. Shame I had to go through the hassle of a full re-install to solve it. but yeah.
