I need help which i guess you know from the title, but my games have been lagging when i move my mouse. I've moved drivers to previous ones I've uninstalled them and reinstalled them, I've plugged my mouse into different usb slots (my old mouse broke... *frowney face*). Certain games work though like Arma 2, War Thunder and World of Tanks but most lag like Planetside 2 and L.A. Noire. All I ask is for some help, I know you guys are some really cool people so I figured that you'd help... please.
i had that issue with some games, switching to an xbox controller got rid of the problem on all of them. i spent days trying to calibrate a machine thinking there was an issue with the hardware or drivers.. i used a bunch of different keyboards/mice all plugged into different ports.. for whatever reason, the xbox controller didn't introduce lag.
the drivers have improved since 13.1, trust me.. should be running 13.5 beta 2... if some games work and others dont.. it's not your hardware, it's their game.
