Hi community

So i have a little problem here i just got simcity 5 for Christmas but when i use WASD to move around i get this blurry line starting in the bottom and goes to the top of the screen then resets to the bottom and does the same thing again. So i searched for it on google and found a forum where someone said it was a overheating or dying GPU (not my post on the forum), but i highly doubt both things because as far as i know my GPU isnt overheating and i bought my PC back in june so i dont think i have a dying GPU either. When i first got my PC there was some problems (crashes in games) but they got fixed after they gave me a new GPU.

i've also had this problem in some other games but not as much as in simcity

Specs
CPU: i5-4670K, 4 x 3.40GHz (Haswell), 3.80 Ghz Turbo
GPU: MSI GTX 660 TwinFrozr 2GB, OverClocked
PSU: Cooler Master G 500W PSU, 80 Plus Bronze

i really hope some of you can help me if you wanna know more specs just ask:)

Have you tried re-installing the video drivers? You should also get something like occt or furmark and run a stress test to see if there are any artifacts, which would let you know its a defective GPU. Is that blurry line something that is visible in every game or just Simcity5?

if you turn on something like v-sync in the game, does the lines go away?

what games does it happen on and what games does it NOT happen on.

The differences might help you find out why.

Artifacts in video can be a sign of overheating or malfunction, and something like Furmark would forces those things to appear, because they challenge the video card, while something like SimCity5 might not do it all the time.

if the lines are only happening when you 'move' the screen, your GPU might be putting out frames faster than your monitor can refresh them and that's why turning on something like Vsync might have a different effect.

when i turned on v-sync in simcity it only happened more often i think im gonna try again though.

The line appears in: simcity, BF3, DayZ the standalone, FC3 blood dragon, Garry's Mod, Planetside 2, Skyrim, Borderlands 2, Batman: Arkham city, Amnesia: The dark descent. (the line is almost not present in some of these games Example: FC3 - BD and Garry's Mod,

The line doesnt appear in: Minecraft, BF4, CSS. TF2, Hitman: absolution, Portal 1 + 2, COD 4

I think its interesting that it doesn't happen in ALL the Source engine games and yet BARELY happens in GM, which is...a Source engine game... :/

what are your display settings for BF3 versus BF4? do you know those off hand? If BF4 is on Medium settings and BF3 is on High or Very High those might be clues.

ok im here with a little update:)

when i jumped into a game of simcity i couldnt mke the line appear and the same in DayZ, so i havent recorded it yet. I just found my old Battlefield: Bad Company 2 and i started playing it because let's be honest...it works better than BF4. I didnt seem to have any problem with the game until today where a tiny little blurry line appeared over the screen when i moved the mouse. I think its because i changed some settings in RivaTurnerStatistics but i didnt confirm them so i dont know if thats the case, all i did was changing framerate limit to 60.

i hope some of you will still help me if so i will try to keep you as much updated as possible;)
