Guys, I really need help as I'm getting sick of this. My PC recently started having a very bad input lag (mostly mouse) without any reason. The thing is, at first it's ok, then the more the game goes on, the laggier it gets until it gets nearly unplayable, because my mouse responds soo slowly. The thing is, I did notice this being a thing before but it would get only A BIT laggier and then stay that way. Now, it gets so laggy it's unbelievable. My PC is beefy enough for games like BF3 yet there is such a bad lag it's killing me. I've tried it all, even Windows reinstall several times with different drivers. Temps are ok, nothing is throttling, nothing is overclocked. Commands like "disable platform clock" and such help only with the mouse smoothness, but lag is always there and gets worse as the game goes on, it's driving me crazy and I can't understand what's going on. Is my hardware going bad? Thanks.
