I just bought a GTX 770 thinking that would surely eliminate my problems but no.
I was playing Tomb Raider this morning on max settings beautifully. Then some Metro 2033 with some screen tearing but not bad. Then I play sleeping dogs and I get horrible drops in frame-rate and overall laggy/ juttery performance. I went back to Tomb Raider to make sure it still played well and it does. WTH?
My rig is:
8GB 1600 DDR 3 RAM
MD Phenom II X6 1090T Black Edition Thuban 3.2GHz Socket AM3 125W Six-Core Desktop Processor HDT90ZFBGRBOX
