It happens to me in BF4 (because it's the only shooter I play). After some search in google I found that, while it is not that frequent, it might occur in some other shooters too (planetside 2 for instance), so it's not a specific problem of a single game. As you can see in the BF thread, it happens with some other mice too. Some people said they fixed it by updating/reinstalling their mouse drivers, others fixed it by switching to another mouse (which I'd prefer to avoid). Now, given that Xornet hasn't his dedicated drivers, I honestly don't know what to do. All I know is that the game is unplayable this way. Do you have any suggestion/fix for that? It's kind of frustrating
