Hey guys, I dunno much about computers, but i have this spec intel G5 2.8GHz Intel Core 2 Duo 2 GB 667 MHz DDR2 SDRAM and ive bought and installed battlefield bad company 2 on bootcamp (winXP), but whenever i try to play it, even on lowest graphics, there're these horizontal lines everywhere all the time, and whenever there's ANY damage on anything, the original of it keeps flashing constantly so i can't tell if somethings destroyed or not. for example if a building goes down, the animation for it happens and the debris is on the floor, but the image of the original building stays but keeps flashing. so its so hard to play and im really disappointed right now... walls/buildings/plants all keep flashing... is there any way to fix this? i read up on something called vsync and switched it on but it didnt do anything any help would be appreciated!!
