I have the standalone and my ping is great. When I double tap W to sprint my guy goes about half the speed as anyone else and looks like hes running in slow motion. I was well fed and hydrated and could not figure out the problem so I killed that character off and started a fresh spawn with the exact same problem. After that I uninstalled the game 2x and still had the same problem with brand new characters on default settings. I've found that this bug has been around since 2012 from what I can tell. Does anyone have any insight here? I did delete the dayz folder in my documents when I reinstalled FYI. Thanks.
EDIT - I have fixed this after several uninstalls and reinstalled grfx driver and deleting all dayz files from my PC.
