HELP Please, flickering black lines and squares!

[aries12]

When I start the game there are flickering black lines and weird polygons. It happens only when I start the game and only in rooms like houses, not in roads or in streets, especially near the light of lamps or televisions (but the effect is on all the screen). After 5-10 minutes of playing, these flickering lines disappear form everywhere and the game is perfect even if I return in those rooms. Why??? These flickering lines and squares also disappear when I turn reflection details down.
My Pc is all new (I bought it on March 2017): AMD Athlon quad core, Nvidia GTX 1050, 8 GB Ram, monitor Philips 5 ms 1920x1080.
Sorry for my english, I'm Italian.

Sounds weird. Have you tried turning on and off certain visual effects and tweaks in the game? Perhaps some odd incompatibility with your drivers or hardware?

Thanks for the answer. Yes, I have, the only option that changes something is "reflection details". If I turn it down, the squares disappear but not the black lines. The game is perfect after a period of gaming, after 5-10 minutes.
Those strange effects are only in apartments, not outdoor, not in the city (only 1 time I have seen that outdoor).
I'M FURIOUS BECAUSE THIS IS MY FAVOURITE GAME. I HAVE WAITED FOR THREE YEARS TO PLAY SAINTS ROW 3 BECAUSE MY OLD COMPUTER HAD A BAD FRAMERATE. NOW I HAVE A SUPER PC, AND THESE THINGS HAPPEN ONLY IN SAINTS ROW 3, NOT IN THE OTHER GAMES. 3 YEARS!!!

I can confim I too have this exact same issue, I am not so sure about black squares but I do see flickering black lines every where, and only in interiors. My set up happens to be simular to yours.

16 GB RAM DDR3

NVIDIA GTX 680

AMD FX 8-core

Monitor: AOC also @ 1920x1080

Perhaps it has something to do with resolution? I would like to have some answers as well.

@aries12 "I'M FURIOUS"

Well look at the bright side, it only happens in interiors but you spend most of the game outside.

[aries12]

yes, you're right ^_^. Thanks for the answer bro!
But after 5-10 minutes even the interiors are ok. It's an annoying thing when you start the game only.

Yup, just noticed that too. Oh well, older game I suppose.
