Bug Report Black screen with cursor @gamecapture

[jakob558]

Hi community,

Out of nothing, I got a problem with OBS. I recently reinstalled my NVidia drivers, since my HDMI output was not working anymore.

I have an Asus N55SF-1194 with an i7 2670, GT555m and 8 GB of RAM.
I was streaming with a lot of joy at 720P@60fps w/o any problems at all.

But after I reinstalled my NVidia drivers (did it properly with sweeping the older drivers first), I cannot get Gamecapture to work. All I get is a black screen with a cursor. It does show the right cursor (it changes ingame) but it is not showing the game. I tried a lot of solutions, I am running Win7 Ultimate 64bit with 32bit OBS (32bit can capture League of Legends, 64 cannot :)). I run OBS on my GT555 and not the Intel graphics thing. I run OBS in admin mode.

I really do not know what to do anymore. It is really weird because it used to work with my laptop. Maybe you guys can think of something I did or that happened that is causing the problems. Here are my logs:

I know you said that OBS is already running on the nVIDIA, but is Leage of Legends running on it as well? Currently, both OBS and the game need to be running on the same GPU for game capture to work.

 

[jakob558]

Oh, I still forgot some info ;)

Yes, both OBS and LoL are running on the nVIDIA chip. I see that on the nVIDIA chip, an DVI output is running as well. I am using only one screen, but it is an extern screen on HDMI, with the laptop screen turned off, I don't know if that has something to do with it btw.

 

[jakob558]

Oke, this is really weird. I do not know how, but apparently I fixed the problem. I see my game on OBS now. Maybe it has something to do that last time I tried, I was using the screen that is in the laptop, wich does not use the nVIDIA chip as its primary GPU. I am going to test it on my laptop screen now. The optimus thing is really complex, that's one thing I learned the last couple of days ;)

Ah yeah, that nVIDIA Optimus thing is known to cause trouble with OBS, glad it worked itself out though. :)
