Question / Help Optimize stream for CS:GO

[Blank]

I'm trying to get the stream to look smoother without going down to 480p, while being able to maintain about 90 - 100 fps in game. (without streaming I get about 90 - 140 fps, fluctuating. while streaming i do fps_max 120. CS:GO is at minimum graphic settings)

What should I be changing? 720p/60 fps made in game feel laggy, while at 720p/30 fps the stream didnt look fluid.

I used the analyzer:

If you are having problems and are using a laptop, see this thread for advice.

If you are using SLI or Crossfire, you may need to disable it for compatibility with OBS.

1 issues found (0 major, 1 minor).

I've checked NVIDIA settings to make sure OBS 64-bit is using the NVIDIA GPU. In my OBS however, there are two identical GPUs to select from in the dropdown.

Intel Core i7-3630QM @ 2.40 GHz
Nvidia Geforce GT 650 M
Intel HD 4000 (Optimus)
8 GB RAM

Current settings:

CBR: On
Max Bitrate: 3500

Base Resolution: 1920 x 1080
Downscale: 1.75 (1096 x 616)
FPS: 60
Aero Enabled

Multithreaded Optimizations: Ticked
Process priority class: Above Normal
CPU Preset: Veryfast
X264 Encoding Profile: High
Use CFR: Ticked

Its always Green for me at 3000 bit rate or 3500 bit rate while streaming, no dropped frames. the testmy speed is quite a huge difference tho

Test video at current settings: http://www.twitch.tv/blankshotx/b/480839551
About 70 - 80 fps in game.

The only way to lower the impact on game performance is to lower your stream quality. If you can't stand a 30fps stream, then you'll have to downscale hard, or lower your x264 preset to superfast or ultrafast. Alternatively, you could give QuickSync a shot.

This is why people build a second PC as a dedicated streaming/encoding box.

I'm reading the quicksync threads and most have a [1] [2] monitor setup in the monitor settings area as a fake monitor.

Would there be any difference for me since I'm using my laptop connected to a 1080p external monitor? If I were to add the 'Intel HD - Try connecting via VGA' it would be the [3] monitor.

My current setup is to 'Show only on 2' and my laptop screen [1] is blacked out.
