Hi guys

I'm a moroccan streamer and I have recently upgraded my laptop. Before I had i5 2.4 Ghz (2cores), nvidia gt 520mx, 6 gb of Ram. I could stream using quicksync with a downscale resolution of 720p.

Now my new computer (bought 1 week ago) specs are (resolution downscale to 720p). I'm streaming league of legends very high settings.

- Intel® Core™ i7-4710HQ (2,5 GHz)* ->> Turbo mode 3.50GHz
- NVIDIA® GeForce™ GTX 860M
- RAM : 6GB

I have the latest graphic card driver, windows 10.

First using quicksync best quality, my stream went off after 2hours.
So I changed it to best speed, in case. I'm udner the impression that my laptop is really strugling handling this.
I changed from quicksync to nvenc, when I watch my past broadcast, I notice some lags in the stream.

Guys, what's wrong? Is it windows 10 messing up with obs? My computer is new there is almost no software in it.
I'm so disapointed, is my laptop not powerfull enough to handle League of Letgends (very high settings) while streaming??

Thanks a lot for your help !
 
While I can never recommend a Laptop for the purpose of streaming, in general your system should be capable. The logs show some late/duplicated frames though which explain the lags you mentioned.
I have to say the reason is a bit unclear though. What you could try is see if lowering your graphic settings in LoL helps, and you could try using the standard x264 encoder instead of a hardware encoder.
Personally I also always keep an eye on my cpu usage and system resources using Process Explorer to see if I run into a limit.
 
Normally the standard x264 requires even more ressource from CPU. It is going to be more laggy if I check this option.
I am going to add some RAM though (switch the 4GO of Ram from my old laptop to the new one) because I see in one of the two logs that the available RAM is ridiclously low.

I know that laptops are not good for streaming. But I can't believe that in my previous laptop (obviously far less powerfull), I never had any lag using QuickSync (Best Speed) + League of Legends (low settings). And the laptop was 3years old running in windows 7.

And Seriously, League of Legends was never supposed to require a good computer. I mean I'm not trying to stream CS Go or the last Battlefield. I am convinced there is a problem of optimisation somewhere or Windows 10 is really not synergizing well with OBS.

This is really not normal and I would really love more investigation from the Staff if possible. I can provied additional logs, or performance scaners or anything else if needed.

Many Thanks.
 
The problem is the missing optimization for Windows 10.
A lot of people expirience the same problem of high CPU usage while using OBS on Windows 10 machines.
Your laptop simply cant keep up with the current settings under windows10, but would be able to do so while using 8.1.

So far we got only 2 small fixes for Windows 10, but only for that stuff that was broken completly, no optimization yet.
Thats a big problem, but the only thing we can do is providing feedback and keep the request alive and on top, so people would actually look at it.
The only thing that is strange - this started pretty late, somewhere around build 10240 of windows 10, before we had the usual CPU usage from OBS, pretty much the same what we saw on windows 8.1 on the same rig.
 
You are assuming it's missing optimization for windows 10, but noone knows why some ppl have less performance and some ppl don't.

Anyway, @transatlas the log you posted was on 0.654b and league of legends seems to be using memory capture, pls post a log from 0.655b
 
First of all why do I read this.
"20:17:08: Physical Memory: 4095MB Total, 2569MB Free"

I have 5.9GB in total (just checked in task manager), why can't OBS detect my total amount of RAM?
 
Because a 32-bits application can't use more.
Btw, that is a log from yesterday using 0.654b, do you have 0.655b installed?
 
I have asbolutely no idea why there are 2 versions (64/32 bits) of OBS installed in my computer.
Well I have to guess that I launched yesterday stream on the 32 bits 0.654b version.

I streamed monday on the new version and 64bits though. Here is the log : http://pastebin.com/wnUNAsch
 
Well after reading some threads, I think there is a problem with quicksync and windows 10. When I use quicksync, after 1/2/3 hours my new laptop freezes, blue screen with an error "video encoder" or I don't know.
I'm just going to use x264 and I have one question concerning this. I want to stream 720p (resolution downscale from 1920*1080p) with x264 ultra fast, what's the minimum bit rate needed? I want to put the lowest bit rate possible without affecting too hard the quality because Twitch takes time to give me the multiquality option. Many of my viewers have low internet speed connection.

Thx guys !
 
If you want quality with a low bitrate - keep the preset slower. Ultrafast would look pretty bad if you try to do 720 with ~2000bitrate. Try veryfast, if your CPU cant keep up - go 1 step faster.
 
Well I was using 2000bit rate with quisync/NVENC. It didn't look bad.
Normally x264 (even in ultra fast) is better anthan quicksync/NVENC (even if high quality preset is used) so I could even lower the bitrate?

Whats is the minimum bitrate for x264 (ultrafast) and x264 (very fast)? Any website or benchmark or statistics on this question?

Thx !

This is just how it always has been, on this pc these drivers work perfectly, and on the next nothing works right. Silicon is a very feisty woman.
