Question / Help Choppy Gameplay / Screen Tearing

[zartheur]

I've been streaming my gaming desktop via a capture card on my laptop and when i look back at the vods the gameplay to me looks choppy and pixellated, and i've also noticed screen tearing. I don't know if it has to do with my connection or my laptop not being able to keep up with everything, but help would be appreciated.

Thank you in advance.

Actually, the vid. looked pretty darn good. What you can try is down scaling to 720p. Your bitrate is a little high unless you're a partner because you may lose some viewers because of their internet connection. Also, do you use game capture? What version of Windows are you running? But i think for a laptop...you need to upgrade your RAM to at least 8g if you're going to use it for streaming as well as game play.

Whenever I down scale it just looks blurry and horrible so I don't think that's really an option cause I have no idea how to improve it. & my laptop is actually just strictly for streaming, no gameplay. I use the xcapture-1 to capture what's going on on my desktop. Do you still think I'll need to upgrade my ram? & I'm running Windows 7 64 bit.

@OminousZ He's running the 32-bit version of OBS which will never report more than 4GB of RAM. Windows version is listed in the log file - 6.1 Build 7601 S - which is Windows 7.

@zartheur How are you sending data to the XCAPTURE-1? Are using using its passthrough option or cloning your primary display or using a splitter or what? I assume you have vsync enabled on the desktop PC.

Regarding image quality, if you aren't happy with how 1920x1080 looks at 3500 Kbps then you have to downscale. The Twitch limit of 3500 Kbps isn't enough to make a lot of higher motion 1080p content look decent. Downscaling is the answer.

I hooked my xcapture straight to my graphics card and cloned my first screen(which I play games on) to that. I do not have vsync enabled because I don't like how the fps fluctuates if I drop a couple of frames in crowded areas. & it's not that I don't like the way it looks I most certainly do I just would like to know how to fix some of the choppyness and screen tearing. Would using the 64-bit version help at all?

 

[Sapiens]

No, the 64-bit version of OBS wouldn't make a difference. You're most likely going to need to enable vsync if you want to eliminate tearing.
