Question / Help Drastic FPS drop when streaming SC2

Hello,

I've trying to stream some Starcraft2, but I can't seem to fix the FPS drop problem I'm having.
Anything else than SC2 streams at the desired rate (i.e. 30 FPS by default), but as soon as I'm ingame OBS shows a drop to 9! FPS, making it pretty nasty to watch.
I've fumbled around the settings hoping to find the right ones for my setup but this just doesnt make sense to me, as my PC is showing relatively low CPU usage, and FPS ingame are around 150+ with Extreme Graphics Details.

What am I doing wrong? Any ideas? Thanks in advance!

Log attached (using the settings that work "least horribly" for me right now).

It's because of your graphics adapter, the 2xx geforce series stalls too much. It really needs an upgrade.
 
Hmm so... its sufficient to run several games at once, on 3 screens, on ultra / high details but.. not to stream one single game with more than 9 FPS? Seems odd. ;(
 
Yep, because (IIRC) it mostly bypasses the graphics card when you switch on QSV.

I'd also say that you're drastically overstating the 285's abilities, unless those games on ultra/high are from the (very) early 2000s. Especially as a single 285 can't drive three displays as far as I know (nVidia cheaped out on the RAMDACs... again), only an SLI'd setup can swing that. And SLI screws up how OBS uses the graphics card as well, anyway. And your logfile doesn't show an SLI setup, either.

Yeah, I used to have one too. The 2xx series specifically are known to have weird problems all over the place. You really need an upgrade.
 
Hey,

You're def. right about the fact that 2xx is getting old, but I assure you I'm running SC2 on Extreme at 1920x1080 and reach 150 FPS ingame without any problem! The most recent games work just fine too on mid to high settings.

Also, there are only 2 screens plugged to the gefocre, the third one is plugged via HDMI into my motherboard - thats probably why it now works a lot better than via the 2xx.

And youre right, I need an upgrade :)
 
A GPU being able to play games and a GPU being able to do what OBS demands are two different things. Your GPU has to have fast VRAM to handle all the texture copying that OBS does, and the 2xx series is notorious for having slow VRAM. So you may be able to play games alright, but OBS will suffer.
