Question / Help FPS Issues, Lag in OBS but not in game

[SwishnSteph]

Hey there, been streaming for a while, mostly with Windows 7. I had a lag issue when first starting but I adjusted a few things and got it working a-ok. I have an i5 processor and a GeForce GTX 960. I had been streaming with 1920x1080 and 60fps in my OBS Studio settings and I really had no issues no matter what game I played.
The other day I updated to Windows 10 and my first stream back I had to just go offline because every time I would click in to the game, my FPS would cut in half and keep dropping. I was hovering around 10 FPS in matches and it would go back to normal when the round would end or if I would go to full screen web cam and get out of the game entirely then the frames would stabilize. But any time I click back in to the game, even just in a start menu of the game, my frames suffer.
And OBS doesn't say I'm dropping frames, but next to where it shows you the CPU on the bottom right, I can see my FPS jumping all over.
I've been playing with settings for two days now, lowered resolutions, disabled background operations on my pc- really digging deep here- and I've been able to improve the lag, but not cure it entirely.

Here's a log file: https://gist.github.com/17c2fbd482b0414475f1165c62f74fc9

The other day I updated to Windows 10

too bad, win10 after CU update causes more problems than has benefits
I have also 6600k@4,6 + 960 and you cant succesfully play and stream 1080p60 with this cpu unless using nvenc or quicksync

anyway you are maxing your gpu. heres the cooking recipe to solve this

1. 60hz desktop refresh
2. 60 or 30 in obs
3. 60 in game if there is switch for it (like bf3, bf4, overwatch)
4. enable vsync in game
5. run obs as admin
6. make sure your gpu can do stable 60fps in game without being maxed. OBS needs some of gpu resources as well. If you enabled vsync@60 and its still maxed lower resolution and/or details.
(replace with 59,94 and 29,97 for 59,94 display like hdmi tv)
with 144hz monitor its fastest and most reliable to sacrifice 144 and follow 1,2,3,4
7. Install Afterburner (or pure RTSS+HW Info) to monitor cpu/gpu load and start experimenting with tuning resolution / fps / x264 preset. GPU/CPU load should not exceed 85-90%
