Question / Help Can someone explain this log to me? 60fps issues.

Streaming Path of Exile at 720p/60fps and it doesn't look quite that smooth to me. It seems to be visibly hitching/micro stuttering at times. Is this an OBS/Twitch issue? I see a lot of "buffer full" and p/b-frame dropped stuff in the log, not sure what that's about.

I watched a couple minutes of your VOD and it looked fine, do you have any specific examples of this stuttering? Like a timestamp in the VOD

Near the end of the video, when I'm in the Lower Prison. Maybe the last 8 minutes? I am just seeing a lot of micro-stutters, but it may be because I am not a Twitch partner and not allotted proper bandwidth. I know I can definitely handle 60fps, so I am confused as to why I'm seeing buffer full and frame drops.

Glad to hear that. As a note, frame drops occur when your connection can't handle what you're trying to output. Could be your connection just being too saturated for a quick moment. You have a really low amount of frame drops though, so it's nothing to be worried about.

With 10mbps up, I would assume that I could handle a measly 3k bitrate/buffer. I had it at 3500 before, but decided to drop it because I don't think I need that extra 500 for 720p.

Even if I do have p/b frame drops, as long as they're very low, that's okay? I may experiment more with a slightly higher bitrate for more clarity in the picture, but I don't think I'm going to move it from Quality 8. I doubt I'd see much improvement at all.

Yeah, if they're really low, that's fine. 378 frames dropped out of 276216 is very very little. My guess is that something might have caused your network connection to slowed for just a moment, and while that happened you dropped a few seconds worth of frames, and that's it.

Video isn't 60 FPS in some places (drops to low 50's, mid 40's), but other than that I don't really see any problems.

I suffer the same kind of thing sometimes; don't know why; I just assume it's a congestion issue with the streaming service.

I also can't do 1080p60 for some reason despite my CPU/GPU never maxing out; sometimes not even being close. Network connection isn't maxing out either. Just another issue I can't figure out the cause of.

Yeah, it's odd, isn't it? I've checked my logs for my connection and it's not even close to being maxed out. I think it's an unfortunate issue of streaming. You're going to run into issues without any explanation or fix.

Personally, I blame Twitch.

I really don't understand the full buffer stuff. It's not my connection at all.

I'm supposed to have 10mbps upload. What's up with this? When I upload Youtube videos it's super fast. Is this actually telling me I have 3mbps upload? I have a Netgear WNDR3700v4 router with the latest firmware.

I ran it again and this looks much better.

Well, the first shaper probe test was to a server in the UK, the second one was to a server in Kansas City. This likely explains the discrepancy. Anyway, as long as you are streaming the the NYC or the Ashburn servers, you shouldn't have network congestion issues.

edit: oh, I see your last log was indeed to the Ashburn secondary. Very odd. It could just be something over the last couple of days, both Ashburn servers are generally quite amazing. You should try one of the other NA servers whenever you have network congestion issues, though. You never know when a server is gonna have a bad day

So long as it's nothing on my end, I'm content with minor issues sometimes. I usually switch off from VA/VA Secondary. NY doesn't ping well for me.

I just ran another Shaperprobe and it gave me a 1.5mbps upload. What's the deal here? Is this my router not doing its job?

Edit: Ran it again, 1358kbps up. lol. I guess I have to return the router.

As you can probably see, the shaper probe tool uses a different server every time, so you have to be aware of the location it's using in these tests as well.

The important bit you are looking for is "No shaper detected" which means "your ISP is not lying about the speeds you are paying to get". Obviously, true network throughput is affected by distance.

That's a good point. I guess I won't go through the trouble of switching anything. The buffer stuff concerns me, but it could have nothing to do with things on my end. It doesn't happen every time either.
