Question / Help OBS Lagging on a high-end'ish system?

[Fragil1ty]

Hey guys, so I'm currently suffering from lag issues on my current set-up, my set-up is as follows:

CPU: i5-3570k @ 3.4GHz (stock)
RAM: 12GB DDR3 @ 1600MHz
HDD: 120GB Corsair Force 3 SSD w/ 2TB Samsung Eco Green HDD for storage
GPU: AMD HD 7850 /w custom overclock settings (925mhz/1300mhz)
Internet: 40mb/20mb

And the settings that I use for OBS are as follows:

Encoding: Quality Balance: 8 / Max Birate: 2500 / codec: AAC / bitrate: 64
Video: Resolution Downscale: 1.50 (1280x720) / filter: blinear (fast) / fps: 30
Advanced: Use multithreaded optimisations: yes/ticked / process priority class: Normal / Scene Buffering time: 400
x264 CPU Preset: faster

Now for example if I stream, my stream is lovely, it appears perfectly, there is no lag on stream what so ever, but in-game, I get lag, so if I play APB:Reloaded I go from a steady FPS of 80-90+ constantly to a low 50-58 and it feels sluggish to play with and this is apparent for most games if not all, I want to stream titles such as: APB/League of Legends/Scrolls/etc, etc but I just cannot deal with losing so many frame.

Is there anything I can do to increase this? as it's starting to become somewhat of an annoyance.

Regards,
Fragil1ty.

Post a log of a live streaming session. They're in %appdata%\OBS\logs and are timestamped with your session date/time.

Also, have you been monitoring your CPU usage and frequency stepping? You are using Faster, which the i5 may not be able to handle in conjunction with the games you're trying to play. Go back to Veryfast. When streaming, your CPU is far more likely to be the hardware bottleneck than your graphics card.

Also, run a 6MB test at http://testmy.net/upload and post the results here. This will test your constant throughput instead of averaged rate (as speedtest.net will check), which is only useful for dead-file transfers.

As you may be able to see, I did change the settings a little bit prior to the stream, but it didn't appear to be much better.

Don't use monitor capture. It is the slowest capture method on Windows 7. Use Window capture with Aero enabled or game capture instead.
