Question / Help Game capture issues black screen

[Itzems]

Pc specs. Fx 8350 8gb 1600 ram (2x4), and gtx 780. I was streaming battlefield 4 perfect with game capture and video capture for my webcam a week ago with little to no performance loss in game. Now I try to stream and my web cam works but game capture is just a black screen and sometimes even freezes my game. I down scale to 540p, use cbr, 1800 birate. Now I made obs admin and no dice. I tried reinstalling and updating all gpu and obs drivers and no dice. I tried using hotkey for game capture and it worked only once but my fps even on low settings were at 10 which is unplayable. What has happened from 1-2 weeks ago. Also could someone help me how do I get my obs to hook to my gpu. I also added obs to nvida control panel and made sure my gtx 780 was selected in video settings. Any suggestions would help slot thank you

Are you using any overlays with BF4? Things like MSI Afterburner, EVGA Precision, any sort of TeamSpeak or Mumble overlay, Fraps, etc. can all interfere with game capture. Is the problem limited to BF4 or is OBS unable to capture other games too?

 

[Itzems]

I do use teamspeak. Haven't tried another game. And I'm using full screen in bf4

I did install a asus dgx sound card three weeks ago. Idk if that could be it but than again it worked fine as of last week

says failed to inject library error code 5 thats my log from tonight

 

[Itzems]

So I clicked game capture properties and clicked the Anti cheat comp. and boom it's working. Hopefully this was the only issue but if anyone has this black screen and was working before check this fix out

 

[Itzems]

Still issues where bf4 won't show up in game capture properties. So I use the hot key but that doesn't seem to work every time

 

[Itzems]

So bf3 on all ultra while streaming I get 100-120fps in game bf4 only gets 35-50 what's the deal any help?

 

[Itzems]

There is a fix. First on game capture properties check anti cheat. Than before going in game disable orgin overlay by going in origins settings. Fixes black screen and in game lag no now stream on high settings 120fpa in game with. 720p 60fps obs settings. Boom problem solved.
