I just put together a new build and have been having issues with video performance in ALL games. Day of Defeat SOURCE and The Battle for Middle Earth 2 both have graphic glitches when playing. First thing I did after installing Vista Ultimate 32 bit was install the chipset drivers then I installed the newest 4800 series drivers directly from the ATI site. Im starting to think that maybe I should have just used the drivers that came with the card.... also there is an updated BIOS for my new motherboard so maybe flashing that will solve some issues.... anyone here have any thoughts or suggestions?
