This only happens to me on cod4 and civ5 and I don't know why and I couldn't find anything on the internet that helped. I don't know if its my graphics card or not but i thought this would be a logical place to start. I'm running an r9 280x(driver 15.12), 8gb ddr3 ram, i5 4460, win 10. The games in question will sometimes artifact for a split second, probably a few frames at best, and sometimes will stop the display for 3-5 seconds.
