what is screen tearing? what causes it?

post #1 of 7
Thread Starter 
So I judt got Bioshock infinite and started game play. Not far into the game (the row boat) I notice screen tearing. So I tried turning the graphics to the lowest settings and they still show up. So I put the graphics back on High and I'm still getting a solid 45-60 FPS. But the same amount of screen tearing. They look like little folds that just appear when they want. Or if I move the camera too fast.

Build:
Cpu: AMD Phenom ii x4 965 BE, 4.02 GHz, 1.4 volts
Cooling: water (closed loop) temps stay at 45c on full load
MOBO: Gigabyte ga-lm3-s2p
Graphics card: Zotac 550TI AMP!, Clocked at 999 MHz, Memory clocked at 2197 MHz. 1.2 volts temps stay around 60c

Screen tearing is a visual artifact in video display where a display device shows information from two or more frames in a single screen draw. It occurs when the game frames isn't in sync with the display's refresh rate. Enabling vsync will fix the problem
if you like playing with vsync on... i dont.

screen tearing happens when the frames that the video card outputs aren't in sync with the display device, this usually happens when the fps is faster than the refresh rate of the monitor. you could try enabling vsync, like boinz suggested and have you turned off the framerate lock in the game that might let the frames go for a solid 60 instead of dipping into the 40's.

go to

C:\Users\*********\Documents\My Games\BioShock Infinite\XGame\Config
open:
XEngine.ini
and change to
[TextureStreaming]
PoolSize=400

just a bit of warning, BI is really really flonky with a graphics card that has less than 2GB of Vram. i know mad.gif

edit: also DISABLE the ingame V-sync! (lock frame rate) if you want to use v-sync use "adaptive" in the NV control panel.

I too have been having issues with BI. Are you saying that this will cancel the terrible stuttering (as it transitions areas) and reduce the horrendous screen tearing?

Sorry, OP. Not stealing your thread but I would like some help on this too redface.gif But what everyone is saying about V-Sync is true. It's because your GPU is having issues synchronizing with a monitor's refresh rate and causes a tear in the screen.
