I think there is VPN's that people claim to be better routing for games. I guess it depends where you are compared to the server your connecting to. Like if your in the EU (UK = EU) and you are playing on a US server then some VPN's might cut down on some routing.
The only specific VPN -type of specific service for games that I've heard of is WTFast. It's been around for 5 years and has some big personalities endorsing it. I've never tried it myself so its up to you if you want to. That's the only one I know.
This is an interview that markeedragon did with WTFast creater Rob Bartlett 5 years ago:
