Okay guys, I have this issue, and have had it for quite a while. I get weird stuttering when using a mouse to control my fps games. If I plug an xbox gamepad in, it completely goes away, most of the time. It happens when I turn, or circle strafe while focusing on an object in game. It gets a jittery/stuttery feel and does not turn smoothly. If I have a gamepad plugged in, smooth as silk. Someone suggested trying another mouse, and I have finally found my old mouse recently and decided to test it out. I normally use a Logitech mx518 wired mouse, so I hooked up this old, ball style mouse to see if it had the same issue. I used crysis 2 for the test, as this is one of the games the gamepad seems to perform admirably on. I fired it up and whoa, the stuttering is much worse with this old mouse than my logitech. I have already disabled mouse pointer precision and any kind of mouse smoothing in any game that has the option. I just can't figure it out. I want to use my Keyboard/mouse controls. Any PC gamer knows this completely trumps the gamepad in fps games. It gives the illusion my game is running poorly, though. Does anyone have any clue as to why this is happening? Also, the old mouse is ps2 connected, and the new mouse and keyboard are both usb. There has to be some kind of underlying problem with my PC. I'm pretty sure my little test has eliminated my mouse. Could it be that using the mouse and keyboard together is causing some kind of interference with one another? Any help would be appreciated.
