Hey,
Settings that I used:
No CBR
Quality banalce 6
Max bitrate 1500
Buffer size 1500
Resolution downscale from 1920x1080 to 1280x720
Filter Lanczos
Fps 48
Process priority class set to above normal (? not sure what its about tho)
x264 cpu preset set to faster
Link to recorded stream:
http://www.twitch.tv/irs0osooom/b/383807640

In fast movement scenes it goes a bit blurry.
Anything that I can change here ?

Re: Need some help with quality balance/process priority/x26

Even with the preset set to faster, your frame rate is set too high for the bit rate you've specified. I stream at a similar bit rate (1600), and i find that you don't really want to go above 30 frames per second for 1280x720.

Re: Need some help with quality balance/process priority/x26

So I should keep all the settings above,but to change only the fps from 48 to 30 ?

Re: Need some help with quality balance/process priority/x26

I should change your fps to 30 that's high enough for your stream and use cbr.
And if you can try to increase your bitrate to 2000.
What's your upload speed? (try speedtest.net to measure your speed)

Re: Need some help with quality balance/process priority/x26

As Helixia said, 1500 bit rate is kinda low for 1280x720, especially for a shooter with higher motion. Have you tried bumping it up to 2000? Is your internet able to handle it?

Re: Need some help with quality balance/process priority/x26

I think it can handle it,but I'm getting lag spikes,even with minimize latency impact.
What about the settings besides the max bitrate on my first post?

Re: Need some help with quality balance/process priority/x26

If you weren't happy with the quality of 48FPS and 1500 bitrate, you aren't going to be happy with the quality of 60fps and only 2000 bitrate. Also, is there a reason you enabled CFR?

Re: Need some help with quality balance/process priority/x26

To be honest?
I just asked someone who streams about his settings,and he got
3k bitrate/buffer
quality at 9
cpu at veryfast
and CFR enabled.

Why I shouldn't use CFR?

Re: Need some help with quality balance/process priority/x26

I think the most important point in this thread has not yet been mentioned:

You shouldn't be changing these settings if you don't know what you're doing. Making a thread about it doesn't help. You should ESPECIALLY not be touching things like process priority and x264 preset. Did you completely ignore the big fat warning you got when you tried to change those settings?

Click to expand...
Actually I changed the priority and preset back to its default,normal and veryfast.
Changes that Im using now:
No CBR
Yes to CFR
Quality banalce 9
Max bitrate 2000
Buffer size 2300
Resolution downscale from 1920x1080 to 1280x720
Filter Bilinear
Fps 48
Process priority class set to normal
x264 cpu preset set to veryfast.

What about delay?
With simple logic,it should help with the stream,right ?
For example delay of 1 minute,you have the time before the streams shown to people.....So,in that time,from my pc it goes to the server,and then being streamed to others. With this logic,stream should actually go smoother without hiccups? Or it just doesn't work this way ?

Re: Need some help with quality balance/process priority/x26

It doesn't work that way. You'll drop frames if you have a bad connection to the server regardless if you are making OBS buffer the video for 1 minute on your own computer.

Re: Need some help with quality balance/process priority/x26

which quality balance should I use with this bitrate? 6 or 9 ?
