I agree with Frant.
For the vast majority of cases if you can see a noticeable lag to a game, no 3rd party software will make it noticeably better. It might make it 'measurably' better by using different routes, as in take a slighter better route if your lucky, and give you 10% less cumulative route lag. But if your in say the 400+ ping range, does dropping to 360+ ping really help?
In the rare case that its a specific node in the route you are taking, using it MIGHT help if they happen to go a different route from you to the game that isn't using any of that same path. But usually that 'bad' route node will be corrected, routed around, etc eventually by just the the way the very natures of internet works(or should work in a perfect world): The ISP will see consistent issues with it for all uses and blacklist to go around it or it will be offline by its providers/hosts to be fixed and auto routing will find you a new one).
Very rarely is huge lag issues not on either of the 'unavoidable' source or target end of the connection (Your ISP's chain out, or game servers in). As if unless you are using a totally crap ISP, or live in a place that only has one 'main out' of the entire region, it will load balance to the best routes it can find between you and where you want to go to.
