There are a couple of tweaks to the registry that I tried yesterday. Probably best not to try these if you are unsure of what you are doing with the registry ... and always make a backup of course
The first tweak is to set TcpAckFrequency to 1 (default is 2). This basically reduces the time your pc waits before sending a response. When I tried this it reduced my old ISP ping on our servers from the usual 44 to around 36, with a similar reduction to the new ISP ping so it worked
It is particularly useful if you regularly play on distant servers (eg USA for me) because the improvement in ping is greater with higher pings. The downside is that it also reduces your download/upload speed, so if you dowload a lot of files it might be too much hassle to keep switching the setting in the register each time you want to play In my case it reduced the dl from about 5.5 to 3.5 and tbh I am happy with around 36 ping gaming on my new settings so I will only use it if I join some online RPG based in the USA.
The second registry tweak is to set TCPNoDelay to 1. It basically stops the PC from waiting to batch small packets together into a larger batch. I use XP and I didn't have the MSMQ folder in my registry, but I tried anyway and I'm not sure it worked correctly, the register merge seemed to insert a duplicate set of folders in my registry (which I undid as soon as I saw it). It might have been my error, but I would not recommend this if the MSMQ folder isn't already there.
This is the site that I found these tweaks on (there are other hits in google with the same tweaks) http://www.sk-gaming.com/content/15500- ... ing_by_150
I wont send pm's as both peeps who were interested obviously read the forum regularly
Also I dropped the link to the original post (Sky Broadband topic) in case that was confusing things
