Question / Help OBS Studio dropping framerate when tabbed into game.

So I'm just trying to stream some good old Heroes of the Storm, I got a new computer the other day with a much better CPU. I tried to stream today only to realize that if I'm tabbed into the game, my framerate will drop to 22-28 (variable), and when tabbed into any other window/program it stays at 30 or 60 (whatever my limit is set to).

I've never had this issue before, I've tried running OBS as admin, i've lowered bit rate, and i don't know what the solution is. To iterate, it is the OBS program itself losing frames. The preview is choppy and so are the green audio bar things. The stream, and OBS, would run at 30/60 FPS if im not tabbed into the game.

Thanks ahead of time.

No streaming in that log.
You have W10 Anniversary Update. Have you disabled Game DVR?

"Game DVR has been turned off by your organization" so I suppose so.

10:24:08.122: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 166 (44.4%)

Encoder preset: change to superfat or ultrafast.
You can also reduce bitrate to 1800 (in this case, don´t use ultrafast : mre pixelated streaming)

You are rescaling in Video settings. Don´t rescale again in Output settings (Uncheck rescaling in Output)

You can try NVENC encoding. Copy profile, edit new one to try this.


===========
My case: (Core2Quad Q6600 and GTX750TI):
- VIDEO settings rescale to 1280x720x30 fps Lanczos https://gyazo.com/71bed7ef37a62c40131eed1a636dc471 (ESP)

- OUTPUT settings NVENC NO RESCALING, profile high, lowlatency high quality https://gyazo.com/58b7a27753b843f4a525cc8b7d4e4640 (ESP)

A quick test with these settings: https://www.twitch.tv/jlbgamer007/v/103002091

(Note: dark colors maybe produced by choosing YUV 709 and color full. Back to 601 and partial (previous test were not so dark -ADVANCED settings-) Previous test: https://www.youtube.com/watch?v=cW_wtT-kxH8
YUV full: https://gyazo.com/1c7c8815d0d6126872bfd52d302ab5e8
YUV partial: https://gyazo.com/9fe315b23684e3cce6e665c4ab0b551b

This should work fine for you.
Better quality: rise bitrate to 3500
