Motherboard: Asus X99-A II SLI/Crossfire
Processor: i7 5820K
CPU Cooler: Noctua NH-U14S Air Cooler
RAM: 32 GB 2133 Mhz DDR4
Graphics: 8 GB Geforce GTX 1070 SC ACX
Hard Drive: 2x 120GB SSD, and Western Black 1TB HDD

Internet speed: 47 Mbps down and 40 Mbps upload.

Hello all! I'm having an odd issue atm.
So whenever I go to use obs at 48 fps @ 720p everything is fine..Until I launch a game.
The fps in the games are easily double (or more) of what I'm trying to stream,
but whenever I open a game my obs fps will drop from 48 to anywhere around 5-35fps (35 is super rare) range and stay there.
I've tried lowering the fps to a 30 cap but the frame still drop (5-25ish).
Oddly enough though my webcam runs perfectly smooth during the whole thing.
It's any game I play (or even running in the background) that the stream starts to runs at 5-35 fps on obs.
Any help would be amazing!

Atm I'm running x264, CRB on, 2500 bitrate, cpu at superfast.
I've attached my log as well.
Thanks so much all!

Also when I use shadow play it works flawlessly.
I have noticed I can temporarily fix the problem with capping frames in game,
but lets be honest. Playing csgo locked in @48 fps on a 144hz monitor isn't ideal.

Looks like your GPU is in the wrong slot on your motherboard, connect it to a 16x slot, which is usually the one closest to the CPU. Also make sure it's seated properly.
