Question / Help Blackscreen/lagg on while playing Gothic 2

[Ixrey]

Hey guys, im not quite sure if i should pack the problems together but yea...
i noticed laggs when playing Gohtic 2 while im streaming with obs classic so i tested out OBS studio, which doesnt cause laggs but the stream remains black. so i dont really care wether i use obs or obs studio as long as it works for me.

my pc specs are
Intel core i5 - 3570k cpu
8 GB RAM
Nvidia GeForce GTX 670

here are my OBS Studio logs: http://pastebin.com/8Jw3GqnF
and heres my OBS log: http://pastebin.com/wDHmX2fA

dont disable aero?
enable vsync
is game running in fullscreen? it should
side note on your settings: 1080p30 will not look good with 3,5k bitrate. consider scaling to 720p30 on video tab in studio. check my signature

i enabled aero again (i used to stream my desktop here and there, that why i disabled it)
i forced the game to enable vsync via my control panel and the game is in full screen still got the black screen.

okay thanks i scaled it down

 

[Ixrey]

so any other ideas?

 

[Mroczny_Gustaw]

just tried and game capture doesnt work as you describe. display capture works well

 

[Ixrey]

yea i cant stream in display capture at all... its always laggy no matter which game i tried

 

[Mroczny_Gustaw]

yes this is general rule with display capture but in this case it works really smooth 60fps no lag - I recorded few minutes with x264 and QSV. consider win8.1 or 10. win7/vista aero likes to lag

for custom resolutions use this

im using windows 7 and as i mentioned earlier i already had disabled aero for display caputre and even tried to stream it... and i already have my resolution so it would appear properly on stream, but it still laggs

 

[Mroczny_Gustaw]

yes , i didnt express myself clearly. I was trying to say that display capture on win8.1 / 10 aero works probably better than win7 non-aero

 

[Ixrey]

so you dont got any further ideas?

nop sry, it worked for me perfectly smooth 1080p60 with display capture on win10 with x264 and QSV
I also just recorded some QSV dead space2 with sweetfx on display capture, same resolution and effect is equally good, VERY minor negligible hiccups when compared to game capture, Id say perfect
another benefit would be easy use of your QSV. I had some trouble using it on win7 like making fake monitors and extending desktops which wouldnt work well for some reason resulting in obs lockups with qsv. on win8.1/10 it just works after enabling in bios and installing driver
