Question / Help Laggy Games Whilst Streaming

[MattGoesLive]

Hey all,
So my new GPU arrived today (ASUS GTX 770 [ Its a BEAST! ] ) and I have been having a go at streaming all sorts of games. However I seem to be getting a few problems in these higher end games and even (surprisingly) Minecraft. These problems were there before the new GPU as well so I am not sure if it is this which is the problem.

The very second I press either "Preview Stream" or "Start Streaming" on OBS, Minecraft seems to just go into spaz mode and act as if it is going at 15-20 FPS however looking at the F3 Menu (And fraps) it shows I am still getting between 150-300 FPS. Any ideas on a fix for this.
My machine specs are

i5-2400 @ 3.1Ghz

ASUS GTX 770 2GB OC edition

8GB Kingston RAM 1333 Mhz

2TB HDD 7200 RPM

My x264 CPU Preset is set to veryfast

I was using a cracked version of xSplit for a long time and managed to do a full 24 hour livestream with less than 100 dropped frames and no in-game lag. Then I decided to be lawful and come across to OBS, it just lags the hell out of me when I start it up.

Thanks in advance guys,
Matt

Please post a log of a live streaming session. They're located in %appdata%\OBS\logs and are timestamped.
Could be a CPU bottleneck issue potentially; can try using the Set Affinity option of Task Manager's processes tab to restrict OBS and your game to separate cores.

Also, if you're using Monitor Capture? Don't. It's the slowest of all capture methods, and I've noticed that it can cause in-game slowdowns as well (Mark of the Ninja cutscenes especially).

Additionally, mentioning any illegal activity whatsoever (even in the past) is strongly advised-against. Along with being a pretty stupid thing to do in general.

If not Monitor Capture then what? It actually seems during League of Legends if I go into game capture and fullscreen my game, it tends to lag a bit more than Monitor Capture. Also I've heard Monitor capture and Window capture are generally the same thing.

use game capture and lol in borderless mode

Incorrect. Game and Window capture have close to the same performance if Aero is enabled; if not, Window Cap is slower. Monitor capture is the slowest of all, causes lagged frames and other unpleasantness.

For LoL, you need two scenes; a Window capture for the launcher/out-of-game menu, and a Game Capture for the in-game client. Fullscreen borderless windowed mode is recommended for a few reasons; not the least of which to allow easier alt-tabbing to adjust things in OBS.
