So every time I enter a red lighting condition in Terraria, such as the underworld and blood moon, these odd lines appear and wig out my screen. My screen is somewhat fine in normal conditions(it'll do this once in a while on normal conditions) They constantly flash in and out when i'm moving and make me lag a little. I have an fps counter and while this is happening, it seems im staying at the same fps, but I still get stuttering. When I go to the retro lighting, it fixes it. However, the retro lighting looks ugly and i'd rather have the regular lighting enabled. I have sli, but even when I turned it off, it still had problems. I turned on vsyinc, thinking maybe it was a display issue, but that still didn't work. I have every setting in my gpu config set for high quality. Also, multicore lighting on Terraria is set to 8, but changing that didn't fix it either. Any ideas?

Specs:
Mobo: Asus 970 pro gaming Aura
Psu: EVGA Supernova 850 G2
GPU: gtx 760 sli
CPU: Amd fx 9370
RAM: Corsair vengeance 2x8 gb

Did you try running the game with a single gpu? If that happens in other occasions as you say i suspect that the main card (the one the monitor is connected) is having some issues. You could also try plugging the monitory to the other card and see what happens.

Yeah, like I said in the post, I disabled SLI. I could try the other connector thing, but it may not work. If it makes any difference, im using a tv as a monitor. That's why I turned on VSync. I've used a tv as a monitor before and didn't have these kinds of issues , however.

I actually solved it myself, I found out it was Hialgo boost. Terraria does most of it's lighting on the cpu, so I guess Hialgo Boost interfered with its cpu work. When I disabled it, the lines stopped appearing, as soon as I enabled it, it was back to glitch city. Luckily, Terraria is almost nothing on my hardware, so I don't actually need it.
