Question / Help Issue with Stream, not at 30FPS

Hey,

So I had used OBS for a while to stream a few games a while ago(about 45 days or so) and it seemed to be working fine, but now it seems to be having issues. My AFK(Overlay) Scene is run fine at 30FPS, but my ingame is shown by OBS to be at around 18FPS ( I have it set to 30). I am wondering what the problem could be. I am attaching the log file here. I am using it to stream StarCraft 2.

I used the log analyzer and it tell me about 30% of my frames were late. Wondering what is happening there.

Your GPU is ancient, and it's choking your system. I suspect your CPU may also not be up to snuff for using the Faster x264 preset, either. Downscale way more, and lower FPS to 25 or so, but really you need some hardware upgrades if you want to stream properly.

Yeah. I was thinking it might be my GPU. I dont play a lot of GPU intensive games and SC2 was running at 100+ fps at medium just fine, but might have to change it now. Do you think a 650ti or AMD 7790 would cut it? I dont want to get a higher end GPU because I dont play a lot of high end games, and I'm fine with medium settings at 1080p, game quality over video quality! :)

Both those GPUs should be fine for streaming. You might want to wait a few days, on the 17th, I think, Nvidia is coming out with new video cards at a price point close to what those ones currently sit at.

Ok, but for whatever reason, that log omits which CPU you're using, which as Krazy mentioned could also be a bottleneck for you.

The desktop itself is pretty recent. Its a AMD FX8350, with about 16GB of RAM, just haven't updated the GPU in a while, didn't have a reason to. Hopefully it wont be a bottleneck.

Ok, cool, the FX8350 will be more than enough for what you want to do. That GPU will be a huge upgrade for your OBS performance.

Well, unfortunately that is an extremely low upload rate that you're not going to be able to do much with. You'll want to stick to 480p30fps or lower. You should be able to lower the x264 preset to Fast or Medium with that CPU to get some additional quality, but bitrate is going to be an extremely limiting factor for you.

480p30fps with medium preset should work with 600 bitrate right? and Audio at 96. Trying to get a better internet connection, but this will have to do till I can get fiber around here. I have 16 down, but only 700kbps up :(

That's extremely tight, being that close to your cap. Are you playing internet games? You might be ok with single player games (or a local lan party), but if you're playing an internet game then you need to leave some bandwidth for it as well. And people rarely get their full theoretical bandwidth (although some people get even more). You'll just have to experiment to zero in on your best bitrate, worry about the resolution, fps, preset once you have that figured out.

You *might* be ok. But you'll really have to tweak bitrate settings until everything is right

Got the 260x today and the FPS was fine at 30FPS constant, but having other weird issues with SC2 instead. Off to blizzard for support help now! My SC2 performance is worse now. At medium settings barely manage 40FPS mid game (got 70+ with the 9800GT)
