I have recently been attempting to upgrade my stream to 60fps, as somehow I now have quality options on twitch and I'd like to take advantage of that. And when I click on OBS and have the window on top, there is no problems, works great.
However as soon as I click back into the game, it drops, hard. into the high teens and mid twenties. Not dropped frames from bandwidth issues. When I lock my framerate in game to 60, or anything enough to lower my GPU usage. it goes back to 60fps and there's little issue. However, whenever there's any kind of GPU spike from the game, like a lot of explosions or whatever it may be, OBS drops back to that 20fps range.
Before I have been streaming at 30fps, and even if my GPU usage was maxed, or my game dipped below 30fps. OBS was still solid at 30. I am using NVENC so it would make sense that performance would be affected by other things using the GPU. however, the same thing happens when using X264 or any other encoder.
OBS settings:
I am using OBS classic
Encoding - NVENC encoder, 5000kbps
Video - Resolution 1920x1080, downscaling none, FPS 60
Advanced - process priority high, scene buffer 700, encoding preset high quality, profile main, 2pass off
System Specs:
GTX 970
I5-3570k
16gb ram
If there's anything information I did not provide in this post just ask and I can add it.
Here is this post in video form letting you see it for yourself (when it's done prossessing) https://youtu.be/nK4yLVyQIUs (YT: OBS dropping framerate when game is selected.)
