Lets re-visit this: This is directed at ESET Devs.
Fact: Something in your AV program ( 7.0.302.0 ) is causing serious lag in games and slow responses; Gamers are dropping ESET for other products because you are not LISTENING. They don't have time to deal with your company if your not going to listen, they are just moving on to the dozens of other products on the market.
Let take the latest Battlefield 4 on PC for example. The Battlelog will not even freaking loadup and a webpage. Why would a basic AV only program prevent that without any warnings? Why?
As a customer of Eset ( AV only ) of 12 years, I am highly pissed to see the lack of responses. This forum alone is littered with issues with games.
