Question / Help Need help with Quick Sync

I'm not sure if this is normal but I get huge fps drops while streaming with Quick Sync, which I thought the appeal of Quick Sync was to make your games run without the typical streaming lag. As well is there any way to use game capture or am I stuck to using monitor capture? Using monitor capture pretty much makes my games unplayable due to brightness(my monitor needs negative brightness on desktop to look reasonable), also the FPS drops from playing in windowed mode itself(which is not too bad compared to the drops from Quick Sync streaming).

In a place where I would get around 200 fps normally it drops to about 100 while streaming with QS. While streaming without QS I don't drop nearly as much albeit with a lower fps of 40. I'm hoping ShadowPlay becomes Twitch enabled soon to solve my streaming woes

My Setup:
Intel 3570k @ 4.5ghz
HD 4000 with memory set to maximum(1024 I think)
GTX 770 ACX
ASUS VG248QE 144hz

My Settings
1920x1080 I've tried this default and downscaled 1.25-1.5
FPS 50-60(runs with no frames dropped and the stream looks great)

Any response would be greatly appreciated!

Yeah, it kind of sounds like QSV wasn't set up properly or something. It really should result in practically 0 performance impact on your game.

Hopefully you're right and that I can fix it, or that it's something silly that I've overlooked.

Er, well don't use Monitor Capture for one, it's the slowest capture method in Windows 7. QSV seems to be performing fine, but I can't really recommend 1080p60fps. Between flash player not handling it well, and the steep bitrate requirements (on top of the extra you need for QuickSync) it's not going to be a great viewing experience.

Turn Aero back on, use Game Capture, and go down to 720p if you want 60fps, or 30fps if you want 1080p.

"As well is there any way to use game capture or am I stuck to using monitor capture?"

Unfortunately I haven't been able to use game capture with QSV like I normally do, searching with google I found at least another person who had the same problem(actually how I figured out how to fix it using monitor capture instead).

edit: To be more clear, when I use game capture it just comes up as a black screen while the audio still works.

That's...odd. It absolutely should be working. Window Capture with Aero enabled usually breaks with the Intel iGPU enabled, not game capture. I'm not sure what else to suggest, tbh. I'll point the quicksync dev, Palana, in this thread's direction. He should know more.

edit: Oh wait

That means OBS is running on the Intel GPU, which it shouldn't be doing. Did you change the selected adapter in Settings>Video? It should be your desktop GPU, not the Intel one.

Thanks a lot for the help! I originally thought that the Intel HD4000 had to be selected, but that wasn't working out too well. So I tried it with the Nvidia selected but when I had that and QSV checked I was getting an error(only with the Nvidia selected), so I figured my first thought was right and that something else was done wrong. I just went back and tried it out with Nvidia selected and I didn't get any errors and the stream ran better than ever!

I appreciate all the posts, so once again thank you.
