I have seen this problem about on the internet but i cant seem to fix it. I have tried downloading and reinstalling the drivers and that didn't work. I have tried inserting the graphics card and making sure the power connector is plugged in correctly and that didn't seem to work either. As well as the flickering there is also a quiet buzzing sound which starts and stops immediately after a enter and exit the game. I am running a i5 6600k and Gigabyte GTX 1060 6GB displayed on a Benq XL2411Z.
