Hello

This is my first time trying to stream so please bare with me.

I am trying to stream 3 games I play mainly, Arma 2(Dayz) SC2 and WoW.

Literally read thru a couple guides and I've been playing with settings.

Specs
AMD Phenom 2 X4 955 (OC to 3.5GHz)
8GB Ram
Nvidia 660 Ti Power Edition
I get about 56 down 10 Up for my Internet speed.

OBS Current settings
Quality 7
Max Bit: 3200 (Buffer the same)
Base Resolution 1920 x 1280
And I've Downsacled it to 1.75 (1096x730)
FPS: 30

So first off I've literally only ran it a while and ran around in game with it while live streaming.
Didn't notice any In-game FPS lag, but I did notice that the stream just didn't seem idk smooth, And would only get a possible spike here and there.

I just wana know if anyone recommends completely different settings? Literally no idea what I'm doing and I just want to be able to stream with 720p and Good Quality without hindering Performance for myself and the viewer.

Any Information would be Greatful, And if you need anything logs more information just ask!

Wow, So A huge thing I already notice is that speedtest.net shows my upload at 10.1 This website shows me at 3.6. But I see a lot of settings you have I don't have enabled or setup that way.

So I have my Base Resolution at 1920 x 1080 With a downscale of 1.5 to get me 720p

However I did not understand what you meant by Lanczos filter I google'd it and read the article but still unsure how to apply it here? Again sorry for the newbie stuff :(

****Update****

So I copied the settings, However Now I get even more of a stutter during a live stream. This happened when I was playing with it earlier and turned on CBR but not sure what the heck could be causing it. And I've already dropped 75 frames from 3 minutes of testing :(

0.66% isn't all that bad really. I mean, at 48 FPS, 75 frames is roughly 1.5 seconds... total, over a period of 3 minutes. That is not all that bad. But to get rid of it completely, just keep dropping the bitrate in steps of 50 Kbps. So, 3150, 3100, 3050, 3000... I'd imagine it actually not dropping a single frame around 3000 for you.

Awesome, For sure will test tomorrow ( going to bed now ) I'm assuming this would correct the screen randomly stuttering?

If it's stuttering in-game, for you... no, dropping the bitrate would not solve that. If you're talking about stutter on-stream, it probably would resolve that as well, yes. The local stutter tends to imply your CPU and GPU having a bit of an issue with the task at hand. So, if that keeps up you could consider dropping the in-game settings a bit, just to free up some CPU and GPU time.

Hey! So I set my Bitrate at 2800 and It cleared up a lot of the Stream stuttering. In game I almost see no effect on my computer so thats good.

So I did turn off CBR cause it was Giving me MAJOR stutter both on stream and in game. Is this normal?

Also how do you suggest slightly increasing quality without making it stutter?

Thanks again I bet this isn't the easiest thing to help me with :D

Well, with 2800 Kbps being stable, you could just run a higher quality setting for VBR. Given the fact CBR isn't working out for you. Oddly enough. You did not set a custom buffer size, did you? Because that's the most common reason for stutter when using CBR.
