My problem dates back to 03/20/2015, after the purchase of gtx 970, I have spent one year with this problem ( Pixelated Shadows,Texture Pop Ins,Low Draw Distance in all games ), even the color was less clear, after I have changed my graphics card gtx 780 ti and the two first samine this problem has disappeared, after he returned but with 50% less than before is my situation improve, I plan in the future to buy a gtx 1070 or r9 490 with a gold 2k monitor 4k to eliminate the 50% artifact is left, because I have apersu that when I use the dSR 2k picture becomes sharper and aliasing is less visible.
