what is the temp of your card? download the latest catalyst drivers from ati. i think you are seeing artifacts, do you have your card overclocked?
my system is a dell dimension 8400 3.2g pentium 4/ht 1 gig ddr2 ram (533mhz), abit radeon x700 pro 256mb pci express graphics card , dell 19" flat panel display. i have recently started seeing "dots" on objects in some of my 3d games, all of which ran fine at one time. ihave had the abit graphics for about a month and haven't had any problems until about the last week or so. can anyone tell me what this is and how do i fix it?
