Question / Help New to OBS, need some help

Hello,

I've started using OBS, and the setup seemed pretty easy thanks to the guides I read here. But either the guides are missing some info or I'm doing something wrong. Why is that? Because I'm using the recommended settings (using settings estimator) and then even lower of the recommended and still my stream quality sucks.

My computer specs:
i7 870 @2.93
6GB RAM
Nvidia Geforce GTX285
resolution 1680x1050

My current settings in OBS:
Quality balance: 4
max bitrate- buffer : 3000
base resolution, custom : 1680x1050
downscale 1,5. 1120x700
the rest default.

With those settings i get an almost smooth stream, but quite bad resolution to pay for that.

Also i'm encountering another problem. I got 2 scenes, one with a background, texts etc and a dota 2 window scaled down and another scene with a normal sized dota 2 window. When I switch from the 2nd scene to the 1st the dota 2 source dissapears. This is what im talking about : http://www.twitch.tv/nedrapter/b/381061450

You shouldn't need to set your quality balance so low with that amount of bitrate for 1120x700. Try setting it to 7 or 8 for DotA2 and see if it improves.

I would suggest to use global source for your game. Maybe it works. As for the lagging thing, usually streams lag because of bandwidth/net issues. Do u experience any frame drops? I find it strange that your system cant handle the stream. So why not trying to set your bitrate at 2000 for example to check if it could work for you and then try to optimize it. You probably know this but you could use speedtest to a serrver near your streaming server to check your real upload bandwidth.

I have selected Frankfurt server @ twitch, and this is the speedtest result I get when I run it with Frankfurt selected

I have added global source for Dota 2 since start. How do I see if I experience any frame drop? What would setting bitrate at 2000 do? (set the buffer at 2000 as well?)

You could always try using CBR.

I'll try that and see what's happening (no idea what CBR initials mean tho or what ir really does :P )

It's Constant Bitrate, should help with some of the lag you experience.

Also, please post a log file if you continue to get stream lag. Frankfurt server is known to cause issues. You may consider changing to Amsterdam or London.

Okay at start changing server seemed to help, but on the 2nd stream it;s lagging a lot again. I notice that my FPS drop to 11-15 while in game and the speed changes from 600-2000. Are those normal? In the screenshot below the game is paused as well.

Also i'm encountering another problem. I got 2 scenes, one with a background, texts etc and a dota 2 window scaled down and another scene with a normal sized dota 2 window. When I switch from the 2nd scene to the 1st the dota 2 source dissapears. This is what im talking about : http://www.twitch.tv/nedrapter/b/381061450

You got any awesome ideas for that too? :D

Did you try the 2000/2000 bitrate/buffer setting? And maybe stick to 30 fps (without using CFR). When you are saying that your speed goes from 600-2000 do u mean the bitrate upload speed? The bitrate is supposed to be variable depending of the complexity of the scenes, so yes it should be this way. If you want a less spiky upload you try CBR on.
As for the "disappearing" issue. Its really very strange. I would try to play around with settings. For example using window capture without global source on etc. Unfortunatelly i cant really help you more than that. Maybe some of the obs "gurus" will have the answer.

You are getting a lot of lagged frames. You may consider limiting your in game FPS to 60 so the GPU has more room to work. You don't seem to actually be dropping frames according to your log.

If possible, could you make a fresh scene with only Game Capture, and delete any Global Sources you might have added. I've seen reports of slide show sources causing lag before. This + limiting in game FPS might alleviate most of your frame lag issues.

As for the disappearing source, I'm not really sure, unfortunately.

You are getting a lot of lagged frames. You may consider limiting your in game FPS to 60 so the GPU has more room to work. You don't seem to actually be dropping frames according to your log.

If possible, could you make a fresh scene with only Game Capture, and delete any Global Sources you might have added. I've seen reports of slide show sources causing lag before. This + limiting in game FPS might alleviate most of your frame lag issues.

As for the disappearing source, I'm not really sure, unfortunately.

How can I limit my game FPS?

When you are saying that your speed goes from 600-2000 do u mean the bitrate upload speed?

Yeap...this is the bitrate and its normal to be this way. If u want/need to be closer to the bitrate you have chosen you can use CBR on (but dont expect better quality but worse in scenes with high complexity imo). Some of my viewers had problems watching my 3.5mbit stream on twitchtv when bitrate sudently was going high so i had to turn CBR on and problems disappeared.

Enabling V-Sync should do the trick. Alternatively, download a tool like EVGA Precision or MSI Afterburner, and there are options to limit framerates.

For example, in EVGA Precision, once installed and both it and the OSD are running, open up the OSD and click the wrench icon. In the General tab there will be a "Framerate limit" line, and you can limit the framerate of things to whatever you choose.
