Lines on in-game movies

Hello and welcome to the forums
Can you post a screenshot please ? is V-sync turned off ? if so then turn it on and check whether it helps or not

I can't seem to get a screenshot of it. The in-game movie shuts down when a press any key. I've tried both the windows 7 driver and the new ones from nvidia but it's the same. If the game doesn't have v-sync in the options menu could that cause the problem?

download fraps from www.fraps.com and take a screenshot with that it should work fine

"Problem, you have a ati crossfire setup and you get 40-50 fps according to fraps, but it feels like 20-30? It's a vsync problem. Forcing vsync in CCC 9.6 doesn't help. Go to the CoJBIB settings in Vista:

C:\Users\[yourname]\Documents\Call of Juarez - Bound in Blood\Out\Settings

To the file video.src and change this:
!VSync() // enable vertical sync
to this:
VSync() // enable vertical sync

It enables the ingame vsync and will give you the fluid gameplay you expect from 40-50 fps! Don't change the gfx settings too much ingame afterwards as it will overwrite your vsync change somehow."

Test this method and see if it helps you or not
