app causes game lag issues

I have an issue while launching games (wow,d3) from the app. With both wow and diablo I get 700-1200ms latency when launching from the app, but when I launch the games without running, I get normal latency ranging from 20-70ms. Anyone know why or know a fix for this. Quite annoying to have to type password and keygen on every game launch, since the app render the games unplayable.
