Last night I played battlefield for about 3 hours straight and in the map rotation we came to a new map I had not played yet. After a few minutes I noticed some long black lines coming out of doorways and extending out from players bodies... I figured uh oh my card must be getting hot or something so I checked temps in GPUz which was running in the background and my maximum temps were only 75c. I did some searching online and found that almost all 560ti users had some artifacting (although with those cards it was MUCH worse see the youtube videos). Is it possible that this is an in game glitch/bug? The card was nice and cool and after I reloaded and played for another 2 1/2 hours I never saw this again (although I didn't come across that map again either). I have everything set to ultra and with the 7970 oc'd I get very smooth fps and no artifacting before or after this event. Should I be concerned about my card? Also if you have noticed this please chime in.
