Question / Help Problems Streaming with OBS

[meteora]

Hello!
I have recently had some problems streaming with OBS and was wondering if you guys could help me out with it.
I've already streamed a game called "Unturned" with a little bit of lag, however when I try to stream other games such as
Project Zomboid, I lag a lot both in game and on stream. I find that a bit ridiculous considering I CAN stream a 3D FPS but not a 2D top down RPG.
I currently don't have the best PC and I'm building a better one soon, but I figured I would ask for help before giving up and waiting to stream until I get my new PC.
Specs:
Dual Core CPU
4 gbs RAM
Zotac GeForce GT630 Synergy edition 3gb graphics card
Windows 7 64x
My monitor is natively at 1600x900 but I play at 1280x720 in windowed mode.

I also have a ~30 mbps download and 5.4 mbps upload rate.

Here's a log from my most recent stream:

Any help would be greatly appreciated.

That is not a log from a stream, that is a log from a preview where encoding was disabled. We'll need a log from an actual stream.
