Question / Help Low fps in SC2 (60/10mbit, Samsung RF511 notebook, log file)

[AdamoA]

Hello everybody!

I got a little problem while I am trying to stream with OBS. Unfortunately my fps is very low after a while and I cannot find the best and balanced settings between good quality and good performance.

I check the log analyzer already plus I set everything what the Stream Settings Estimator recommended to me. Still its not okay :/

While your notebook isn't of the fastest ones out there, you should still be getting playable speeds. Few things: what are your graphics settings in sc2? What method do you use to capture your game (game capture should be used)?

Hello!

First of all thank you for the quick response!

My Sc2 settings are: Windowed (Fullscreen)
Everything Low, 2D and off

I am using game capture, however I got a little fight with until it worked :)

Disable aero, check your processor/gpu load while streaming. If it's at 100% perhaps your machine just isn't enough. Lower encoding quality: bitrate, resolution. Make sure you're not watching your own stream/not running any flash.

meh your cpu is actually an i3 sold under the name of an i5 :/ but it should be able to get 720@25 in my opinion and 5ms render time for an weak notebook cpu isnt bad either but since you run into problems you might downscale a bit more

but i've also heared that several people have problems with sc2 lately if they are playing for quite a time because blizzard changed something essential

Re: Low fps in SC2 (60/10mbit, Samsung RF511 notebook, log f

Thank you all for the response!

I did tests and always checked my CPU usage.
Actually I got a pretty good FPS in SC2 but sometimes (I dunno why) OBS.exe's CPU usage jumps up above 50% for 2-3 seconds and then the FPS in SC2 drops down below 15 :/
I set the bitrate to 1000 but it did not helped, it was the same. It is not constant... but jumping.

I am not sure about the following thins:
- CBR is helping or not (I think yous cos VBR requires more CPU works afaik)
- CFR is helping or not
- key interval should be 50 afaik but it doesn't let me to set. Kayframe interval (seconds, 0=auto) could be between 0-20 actually. I check the Custom x264 Encoder Settings and write keyint=50 but I am not sure it is working like this.

Thank you again!

Re: Low fps in SC2 (60/10mbit, Samsung RF511 notebook, log f

you set a simple 2 in the key interval because thats changed and stands for seconds so instead of the double frames per second you just chose 2 seconds since you had to set a command for it before.

also bitrate doesnt really do much with cpu usage its about the preset and the resolution+fps you try to encode

Thank you, now I can see the problem! :) I set it to 20... but not it is 2. However the problem is still around.
I set the CPU preset to superfast from veryfast... and as far as I saw it was better... can the quality still be good with higher bitrate with superfast CPU preset? Or it is not working like this?

Re: Low fps in SC2 (60/10mbit, Samsung RF511 notebook, log f

well if you go with an faster preset the price you pay for less cpu usage compared to the bitrate needed with the default preset (veryfast) is pretty crazy but your cpu gets quite a lot more headroom

but actually for a 1280x720@25 stream even with superfast preset you should be fine with a 3000bitrate shouldnt be that bad tho
