Question / Help FPS Stutter in CSGO

[Wolf1944]

Hello,

I'm having a bit of an issue streaming CS:GO. When I'm not running OBS, I get 130 to 180 FPS in-game, but it drops a little bit when I stream. The game is still playable, but it's not ideal. I'm able to stream other, more intensive games like GTA V with no issues. Firstly, my specs:

CPU: AMD Phenom II X6 1090T (6 physical cores, 3.2 GHz)
RAM: G.Skill Ripjaws 8GB (2x4GB)
Video: EVGA GeForce GTX 560 SC 2GB
Motherboard: Gigabyte GA-970A-D3

I built the computer almost 3.5 years ago, so I know it's not the best by today's standards. That being said however, I will also say that my CPU is not throttling as my usage never goes higher than about 55% to 60% with both the game and OBS running. Also, my system uses less than 4GB on average. Now, my OBS settings:

Here are some things that I've tried:

• I started out with 3500 bit rate, so I decreased both to 2800.
• Downsized the stream from my native resolution of 1080p to 720p.
• I started out with 60 FPS, dropped it down to 30.
• Set "process priority class" to high. It didn't make a difference, so I set it back to normal.
• Unchecked CFR. It didn't make a difference, so I rechecked it.

Things I didn't try:

• Increasing the x264 CPU Preset to anything higher than "veryfast."

Here's my internet. I wish my upload was higher, but it should be enough for OBS I think. I'm not dropping any frames, and I'm not lagging in-game either.



Also, I'm not sure if it matters much, but here are my launch options in CS:GO. I play on 1280x960 stretched.

• -novid -console -threads 6 -high +cl_updaterate 128 +cl_cmdrate 128 +cl_interp 0 +cl_interp_ratio 1 +rate 128000

And for those who are interested, a preview. The stutter is most noticeable when I switch weapons. Apologies in advance for the background microphone noise. http://www.twitch.tv/mm_wolf/b/668713160

Thanks in advance for any help I get. I can live with it, but if there are any settings that I can tighten up to get rid of that stutter, I'll give them a go.

Charter spectrum, sounds like Wyoming. Should be able to do 1280 x 720 at 60fps, try that as your custom resolution and not downscale.

no this cpu is not by far close to be able streaming 720p60 since he has fps issues streaming 720p30 anyway

it looks like you have some razer tools installed, if it is synapse or anything with some sort of overlay function to display your fps or whatever then please make sure to disable it.

other than that you could try enabling aero and keep using game capture

another option would either using the superfast preset (not recommended) or downscaling a bit further csgo can be streamed in 540p without looking bad.


also make sure to set +fps_max 150 so the source engine has a set limit within reach
