Question / Help Artifacting with sc-512n1-l/dvi

[Hate]

Capture card arrived from japan today. I was very excited to get it up and running only to find out the stream shows terrible horizontal artifacting.

I am using a 2-pc setup. I have tried connecting straight from dvi into capture card with a cable I know is good. I also tried graphics card hdmi out to dvi and graphics card dp out to dvi all returning the same results.

The log doesnt show the details of my gaming pc but its a 3930k with a 980ti(only one dvi-out). Latest nvidia drivers.

Video examples:

The log output.

Any help would be greatly appreciated.

This is screen tearing. It happens when you run with vsync off. Gsync does not work, as the SC512 does not speak that particular proprietary method (no capture card does at present; due to 'proprietary nVidia technology').

Turn vsync on. A capture card is just like a direct digital webcam... it's only going to be able to capture what you hand it, and if that's torn frames, it'll capture torn frames.

I understand it will tear. I am having issues with the horizontal artifacting. Take a closer look at the videos and you can see the artifacting starting out low then going to the top of the screen.

I'm not seeing horizontal artifacting. Can you point out a specific timestamp? The only thing I'm seeing is massive amounts of screen-tearing, starting at the bottom and slowly moving up as the sync rate between the display and capture is very slightly off (which is normal). Again. Turn on vsync.

Tearing = horizontal line of misaligned/delayed frame. Your videos show very visible tearing, starting at the bottom and moving upward.
