Last night i played Dayz on my new computer with Geforce GT 650M SLI and after a long time of game time i went offline to get some sleep. only few hours later when i loged back in and started to move around it was like the screen was jumping. Not sure what to call it since iv never had this problem before. iv tryed to change everything in the Vidio option menu and even in the Config file in documents.i even reinstalled Arma 2 and Dayz mod. but still get the same "lag" anyone had this before and is there away to fix it? Thank.
